Understand The Different Kinds Of Commercial Refrigeration Equipment

The types of refrigerators that are used at home are the most typical example of refrigeration equipment that is used for keeping food and beverages chilled. However, at the same time, commercial refrigeration, which ranges from blast chillers, display freezers to fish refrigerators are also highly in demand. Following is an overview of some particular types of refrigeration options that can be used at commercial venues and their specifications.

Blast Chillers

Blast chillers are one of the common types of refrigeration equipments that are used at commercial venues. There are numerous types of blast chillers that are available for commercial use. The main purpose that these chillers are used for is to lower down the temperature of food to a great extent or to freeze food really quickly, within no time. Based on claims, a majority of chillers take around 90 minutes to lower the temperature of food from 70°F down to under 3°F. Blast chillers are specifically designed to comply with certain food safety and handling regulations. Quite a wide variety of blast chillers are available so when buying one, buyers should make sure that their chosen blast chiller has all the options they require.

Display Freezers

Display freezers and display refrigerators are also one of the most common types of commercial refrigeration option. Generally, convenience stores or grocery stores have this type of freezers and refrigerators to store food items and beverages. These display freezers and refrigerators have see-through doors so customers do not have to open them to look at the items present inside. Often no doors are included in certain types of display refrigerators.

Various food stores often have these display refrigerators in them. Food items stored in the different compartments of these refrigerators are placed within a reachable range and can be directly picked out, which makes them quite convenient. Small sized display freezers and display refrigerators are also available. These small display freezers and refrigerators are generally used for storing drinks or bottled water and can be typically found in grocery stores.

Fish refrigerators

Fish refrigerators are also one of the refrigeration equipment that is generally used at commercial venues such as grocery stores or fish markets. Basically, they are somewhat like typical refrigeration appliances, but they usually have sliding trays so that the fish can be placed over them. The size of these refrigerators should be chosen based on the demand of fish in the grocery store or fish market.

Fish refrigerators are also available in a variety of types that offer a distinct array of options. Since fish need to be kept and stored at proper temperatures, so it is important to ensure that a fish refrigerator that is being purchased will meet these requirements. Even refrigerated fish display cases are also available that make it possible to keep the fish out on display for customers while the temperature of the fishes is effectively maintained.
For those running some sort of a commercial venue where refrigeration is essential needed, these are many other commercial refrigeration options, but these were among the common ones.

Cut Air Conditioning Costs

How Air Conditioning Uses Up Energy

We all want to stay cool during the summer time. But unfortunately, the cost of air conditioning is ridiculous. How can the average citizen still keep paying hundreds of dollars per month just to support their cooling needs? It does not seem like a smart idea to keep paying that much money just for cool air. It is actually possible not to. Did you know that your air conditioner uses up more energy than any other appliance in your home? To be exact, your air conditioner burns 3500 watt-hours per watt hour of use. That is horrible compared to your television which only burns 75 watt-hours per hour of use. A regular window unit doesn't even burn that much, just 900 watts. In comparison to your air conditioner, that is not that bad.

Why the Cost of Air Conditioning is so Costly

As stated earlier, air conditioning burns 3500 watt-hours per hour. This can definitely raise the price on the power bill in only a matter of hours. The average power bill for a house of three occupants usually costs anywhere from 180 to 400 dollars a month. The majority (over half) of your bill comes from your air conditioning system. The older the system, the more energy it uses.

Types of Air Conditioners

Window air conditioners - These air conditioners fit conveniently inside of a medium size window. They typically do not use as much energy as central air conditioning units do. They usually only burn 900 watt-hours per hour.

Central air conditioning system - This is the one that costs so much money. Try to avoid purchasing this kind of cooling system as much as possible. There are other great alternatives to use that work just as effectively.

Ceiling fans - Believe it or not, ceiling fans can be a great alternative to more expensive cooling systems because they work, and are also very affordable.

Attic fans - A fan that is mounts your ceiling. It works by bringing fresh air through open doors or windows in and pushing the air out through your attic. It is also great for getting the hot air out of the attic.

Geothermal system - This is basically loops of piping installed under the ground that circulate water. It is similar to the central air conditioning unit, except that the heat is taken out of the home and put inside of the earth. This system is much more affordable as well.

How You Can Cut Costs

  1. Paint your walls a lighter color. Dark colors attract heat, while lighter colors such as olive green, beige, and white tend to attract cooler air.
  2. Install a metal roof or shingles. This works great because metal reflects heat away from the home.
  3. Plant trees around your home. The shade will keep the sun from beaming directly down onto your house and keep the heat away.
  4. Install blinds and curtains throughout your house. This will help to keep heat from coming in through the windows.
  5. Re-insulate your house. This may take some time and money, but you will be saving thousands in the long run if you put more insulation in your home to keep the heat from getting in.

What You Can Do Now

  1. Place caulk around holes and cracks that are in your home. This will keep cooler air inside of your home, and warmer air out. Not to mention that your air conditioner will not need to run as much to keep your house cool. This in turn will save you money.
  2. Install reflective film on windows. This will help to block 40-60% of the heat away from your home.
  3. Install a couple of ceiling fans. Do not worry, they do not cost much at all. They will usually run you at about $25 dollars per fan. Ceiling fans are a wonderful option because they can keep the air circulating throughout your home without having to leave the air conditioning on, and they help to lower the temperature from up to 10 degrees.
  4. Replace old air conditioner filters. Old filters tend to cause your cooling system to work harder, therefore burning more energy and costing you more out of pocket.
  5. Place solar screens on your windows. They will help to block 60-70% of the heat that travels through windows. You can find solar screens at most home improvement stores.

It is a known fact that cooling systems are very costly, but it does not have to be that way. If you really want to save some cash during this bad economic season, then you will be sure to take all of the proper precautions before summer is officially here. You will not regret taking preventative measures when you are saving thousands per year.

Refrigerated Trailers - Secrets Exposed!

We have seen a lot over the past 12 years with portable refrigerated trailers. As the name implies there really are two key ingredients involved here, the refrigeration and the trailer. We have seen some folks get part of it right while most fail at both aspects when designing and building small refrigerated trailers.

Let's start with the trailer. This is the foundation of everything we do. The regular cargo- enclosed trailer industry has changed over the years so much and they are cutting out the strength and durability we require for refrigerated trailers. It is important not to just get a trailer off the lot and try this at home like so many we see out there today.

Quality built refrigerated trailers should have:

  1. Single Piece Aluminum roof
  2. 16" O.C. steel tube walls
  3. Steel tube roof
  4. Steel tube framed rear doors (not plywood w/ aluminum skin)
  5. Triple tube tongue
  6. L.E.D. lights
  7. Sub floor for superior insulation with aluminum underbelly
  8. Load D or greater tires for better stability
  9. No wood framing or wood walls/ceiling (lighter & stronger with no mold or mildew issues)
  10. Reinforced front nose for refrigeration unit
  11. Extended tongue with mounts for generator
  12. Should be specifically built to be refrigerated trailers and built with strength and durability in mind.

Please check out how important it is to use a trailer made of steel tube instead of z-post or hat post.
We have even seen folks taking walk in coolers and putting them on a flat bed trailer. Be careful as many of these structures are not D.O.T. approved and you can be fined or even worse injure someone. Use common sense, walk in coolers are great for sitting inside or outside a building but they are not designed for the rigors of the road going up and down and side to side, they offer no structural support.

The refrigeration is just as important and you definitely want to get this part right. The ideal solution for businesses is a unit that can be used as either a cooler or a freezer. Please make sure that even if you are purchasing a cooler that the refrigeration system has a defrost capability and preferably hot gas defrost. I mention this because so many folks find out the hard way that if you want your trailer to stay at 35 degrees then your evaporator has to be 12- 15 degrees cooler than that to maintain your temperature. Well it may take 12 hours or 24 hours but eventually you are going to get an ice build up on your coil and you will need a way to defrost it or else lose your product.

Standard refrigeration units that have hot gas defrost is the most effective and fast way to defrost a system. The use of standard refrigeration will save you a bundle in repair and maintenance cost alone. We also recommend modifying your refrigeration system for transportation and do not use copper to connect the evaporator coil to condenser coil. Copper is a soft metal and will break easily. Hopefully these tips serve you well in your search for refrigerated trailers to purchase or rent.

Purchasing the Right Commercial Refrigeration

Refrigeration is an important consideration for everyone. Whether you are talking about home refrigeration for the average person or commercial refrigeration it all matters. Everyone wants to find a refrigeration system that will keep food cold and will allow the food to be healthy and safe to consume.

If you are in the restaurant business then you know that the quality of the food and drinks you serve to your patrons can make or break your company. If you serve food that is cold, old or stale then word will get out and your business will suffer as a result. Both food and drinks need to be stored appropriately so that they will ready to offer to customers when the time comes. What you need is to select the right commercial refrigeration system that will keep foods at the temperatures they are supposed to be at while in storage.

If you are a new restaurateur and do not have much experience with commercial refrigeration then how do you know which system wins top marks and is suitable for your eatery? It helps to talk to those who are in the same business as you are to find out what they have and what you should be looking for. Here are some other factors that you must bear in mind before you buy a refrigeration source for your establishment.

You have to decide what type of refrigerator you need. Commercial refrigerators are larger than standard ones and will make it possible to store larger quantities of foods and foods in bulk. Think about how many frozen products that will need to go into the fridge and freezer areas. When looking at oversized refrigerators you need to ensure that the storing capacity of them is adequate. You also need to consider how many shelves they contain and where you will place each other. Think of your present fridge and try to visualize the food and drink items in the new refrigerator before purchasing it.

The space in the kitchen of your restaurant where the commercial refrigeration unit will go is significant to the one you decide to buy. You need to buy one that is the right fit for the space that is allotted for it. You do not want to spend a great deal of money on a refrigerator that cannot be installed because it is too large for your kitchen.

The best type of refrigerator to purchase is one that is crafted from stainless steel. While stainless steel refrigerators do come with a costly price tag attached to them, they tend to be the most durable and also will prove to be more cost effective over a longer term. It is also less of a chore to clean refrigerators made of this material. If you do some checking you will find that a great number of restaurants, grocery stores, bars, hotels and motels have commercial refrigeration that is stainless steel for all of these reasons.

To keep customers happy and returning for more you need to buy a refrigeration system that is in excellent working condition and will do what it is designed to do. Check around and compare models before you decide which one you want to grace the kitchen of your business.

Using Refrigerated Shipping Containers For Medicines And Medical Supplies

If you work with medical supplies, transport and storage, you know how valuable and important it is that your goods are handled with the utmost care and consideration.

Medicines should be kept in cool temperatures ranging between 3-5 degrees Celsius, away from light; as exposure to heat, light or moisture can lead to a growth of micro-organisms and ultimately, a breakdown of the chemicals in the medicine. This can cause discoloration of the medicine or lead it to not be as effective for the patient. Common medicines that require refrigeration include influenza vaccines and insulin. Blood storage facilities also need to maintain a constant eye on temperature levels.

Storing supplies safely

Finding an effective, efficient and affordable method of storage for all of the medicines and medical supplies is frustrating to say the least. Most companies find themselves purchasing a number of different refrigeration units to keep varied temperatures and store vast amounts. Transport also becomes a problem - either you move the refrigeration unit with you or you have to load everything up onto a cold truck that has been specially designed for the job.

If you're looking for a better way, why not look at a refrigerated storage container solution?

How can refrigerated storage containers help?

A lot of industries are sick of expensive cool rooms and costly refrigeration trucks as their only storage and transportation options for temperature sensitive goods and produce. With their viability as a static and mobile storage option, their affordability and the flexibility in which you can move them, refrigerated storage containers are becoming a popular alternative for many businesses.

Medical supply, storage and transport companies can benefit in a number of ways from using refrigerated containers - saving time, money and working more efficiently than other storage options.

Why is a refrigerated storage container right for my company?

Standard containers come in both 20ft and 40ft sizes and are able to be custom fitted internally with any number of shelving and organizational solutions. You don't need a container for each temperature either - features like dual temperature controls mean you can maximize your use of space far more effectively.

Containers come with a number of different cooling systems. Custom insulation ensures the refrigeration system works as efficiently as possible, with either active, powered systems running off a generator or battery as well as passive systems cooling with phase-change material to add or remove heat as needed. Hybrid systems allow you the best of both worlds, saving on running costs and maintaining incredibly specific temperatures.

Take control of your storage methods and let a refrigerated container work for you. When you work with medicines and medical supplies, efficiency is incredibly important. Stop working with ineffective refrigerated storage and transport methods and make use of refrigerated container systems instead.

Commercial Refrigeration Vs Residential Units: What's the Difference?

At a given time, your home refrigerator probably holds enough food to feed you and your family for about a week. A restaurant refrigerator, on the other hand, has to be stocked every day with enough food to keep a dining room full of paid customers happy, with surplus stock just in case. That's why restaurant kitchens need commercial refrigeration units rather than standard residential fridge models.

But what's the difference between the two? Aside from the sheer volume of food that has to be stored inside, commercial refrigerators have several advantages that help them meet the high performance expectations in a restaurant setting. Whether you're a homeowner or a business owner, when your fridge breaks down, you want to hire the right person to fix it-and for a commercial model, you'll need a repair technician with the training, licensing, and specialized experience to get the job done right.

Size and Layout

It may seem obvious, but commercial fridges must be significantly larger than residential models, which are usually designed to be as sleek and unobtrusive as possible in a home kitchen. Additionally, while residential fridge models often feature an array of shelves and drawers to separate food, commercial models tend to be utilitarian inside: two to four shelves designed for easy food access and stacking. A home unit might have an attached freezer, ice maker, and water dispenser, while in commercial kitchens, those are often separate appliances.

Cooling Power

Commercial refrigeration systems are much more powerful than standard models. This is in part because they're larger and must cool more food at once. Additionally, in a restaurant setting, there are health department codes related to the temperature at which food must be stored. A commercial fridge must keep food at a consistent temperature so that all food that goes out of the kitchen is safe for customers to eat. Note that residential fridge models are often more energy-efficient than commercial units; in order to produce consistent cooling in a large space, a commercial fridge must run constantly.


Residential fridges can come in a variety of shapes, sizes, and materials. You can choose a colored exterior, a plastic finish, or a shiny metal surface, depending on your kitchen decor. With commercial refrigerators, however, aesthetics aren't really a consideration. Most commercial units have a stainless steel exterior for ease of cleaning. There are fewer size and shape options, as well, because in a commercial kitchen, form matters less than function.

Repair Considerations

Because of these differences between residential and commercial refrigerators, not all refrigerator repair technicians will take both house and business calls. In general, it's always a good idea to ensure that the appliance repair professional you hire has experience or training to work on your specific unit, and this is even more vital in a commercial setting. Delayed or improper refrigerator repairs in a restaurant kitchen can shut down the business or make patrons ill, resulting in a loss of income and possible fines from the health department. If you have a commercial refrigeration unit that's not pulling its weight, don't trust your appliance's health to a technician who's under-qualified. Call someone with experience in commercial appliance repair.

Things to Keep in Mind While Shopping For Commercial Refrigeration

Traditional reach-in refrigerators and freezers are not the only applications commercial refrigeration companies offer. Whether for practical or novelty reasons, commercial refrigeration manufacturers offer different products to suit any user's needs.

Maintain a Strong Base

They say the strongest relationships are those built on a strong foundation. Create a strong foundation with your chefs by giving them the tools they need, like a refrigerated chef base. Refrigerated chef bases are an under counter refrigerator and worktable all in one. Better than prep table, the chef base allows the user to have large food preparation equipment, like mixers, and refrigerated food ingredients all in the same place.

Chill Out

Making sure leftovers are not contaminated with harmful bacteria is no longer something to sweat about. Commercial blast chillers assure that leftovers reach a temperature below 40 ÚF before the food poses a threat to customers.

Walk On In

Why waste time figuring out how to rearrange your reach-in refrigerators to cram in more products when you can reduce the strain and triple your storage space with a walk-in refrigerator. Walk-in coolers have enough space to fit full-size storage shelves and any type of refrigerated product.

Got Milk Coolers?

The half-pint of milk is a staple to every school lunch program in the country. The only way to keep the milk properly chilled while being easily accessible for youngsters is by keeping the crates in commercial milk cooler. Milk coolers use an air-curtain-style refrigeration system to make sure that the cartons on top are just as cold as those on bottom.

Prep for the Big Game

Whether making salads, sandwiches or pizzas, refrigerated prep tables keep all of the necessary food ingredients easily on hand. With a storage refrigerator below, a cold pan well on top and a full-length cutting board, prep tables are a must-have piece of commercial refrigeration for any restaurant.

Put the Goods on Display

No deli, bakery or meat counter is complete without a refrigerated display case. Refrigerated display cases feature a large glass window on their front so customers can easily see the products on display. The back of the case has sliding doors so workers can easily pull out a particular customer's desired item.

Raise the Bar

Bar refrigeration is an area of commercial refrigeration essential to any restaurant bar, bar in a home or college dorm. Whether you are going for the cool, clean feel of stainless steel or the sleek appearance of black vinyl, commercial bar refrigeration provides the look and function to suit your needs.

Merchandising is Where the Real Money is Made

Whether a countertop or floor model, sliding door or open air, all refrigerated merchandisers do one thing, increase revenue by allowing customers to quickly select their own products. Refrigerated merchandisers can be used to display everything from wine bottles to prepared sandwiches to bouquets of flowers. Placing the merchandiser near your point of sale will help spur impulse buys.

Settle the Duel with a Dual

Having trouble deciding whether you need a freezer or refrigerator most? Why not try both? Dual temperature refrigeration units provide the best of both worlds, a refrigerator on one side, a freezer on the other and no worries in between. Save on energy costs with a Dutch-door model that allows you to only open half of the compartment at a time and keep that cold air from escaping.

The Benefits of Good Refrigeration

There are many things to consider when it comes to your refrigeration needs. The truth is that most people won't have to ever think too much about keeping their stuff cold. There is plenty of technology already available that will work just fine. Just buy a good refrigerator from the local store and you should do just fine. This doesn't really work for any big business though. A number of businesses need to consider getting a serious refrigeration system to keep their products from spoiling while in storage.

Refrigeration engineering is the science that surrounds just about everything related to the design and maintenance of refrigerators. These are the people you should call if you want to have a special refrigerator designed for your business. They might also be able to help you decide just what you want in the end. They have years of experience in the industry and usually know what their client really needs. I would suggest that you check any one of various online databases to see if the local contractors have a good history. If worse comes to worse, you can always ask around.

This doesn't help much if you don't know if you need one in the first place. This is actually fairly simple. Your industrial refrigeration needs are dependent on what exactly you buy and sell. If you are lucky enough to have only non-perishable products, then you are in the clear already. If you do have products that need to stay cold, then you should analyze just what you really need for your day-to-day operation. It may be cheaper to just rely on a warehouse if you don't actually require much cold storage each day.

If you do decide that you need your own refrigeration, then you need to consider all the options that are available for you. One of the models would be ammonia refrigeration. Ammonia fluids for the coolant pipes are a relatively affordable option for you to consider. It works well and keeps products quite cold. The only consideration is that you shouldn't go cheap on the installation. Ammonia leaks aren't good for general business. There are other alternatives available though, so don't get too set in any one way.

Choosing your own refrigeration source is certainly a difficult process. There's a lot to pick from and a lot to consider in the overall process. The benefits certainly make some consideration worth it though.

Air Conditioning Vs Refrigeration

Having some kind of cold room or refrigerated storage option is crucial for a lot of businesses. There are a number of different ways to keep product and produce cool - what works best will depend on your business model and your needs. When you're trying to decide on the right option for you it's important to understand some of the key differences between the refrigeration techniques that are commonly used.

Air Conditioning and Refrigeration

Air conditioning and refrigeration are the two most commonly used methods of temperature control. Most people will know of and think of air conditioning because they use it in their homes. With a standard temperature of 22 degrees to ensure human comfort, air conditioners have a limited range when it comes to cooling. Refrigeration allows for much greater alterations in temperature with the ability to cool to around negative 30 and even heat to 25 degrees or more. For most cargo and produce, refrigeration is the only way to go.

How do they work?

Cold is the absence of heat rather than the presence of something else and refrigeration of any kind works by removing heat from an environment. Air conditioners use fans to project and circulate cool air into a room or container to keep temperatures low.

Refrigeration systems use a series of tubes and vents to circulate cold gases and liquids to alter temperature. Air is sucked into a compressor and recycled through the system.

Air conditioners usually have a stricter set of requirements for the air that they use for cooling. Most systems need air to be filtered and purified to ensure that no dust particles build up inside the unit. A certain level of humidity is also required depending on the type of cargo or produce that is being stored. Refrigeration systems don't have this set of requirements to maintain temperature.

What should I use?

For humans and animals, air conditioning systems tend to provide a more comfortable environment with a constant fresh air supply. If you are storing temperature sensitive produce and products, then refrigeration is a definite winner. You'll have more control over any desired temperature with a good refrigeration system.

Keep your produce cool with a refrigeration system. Consider a refrigerated container for more mobility and as a cheaper storage option instead of building an expensive cold room. Cool more efficiently with a refrigerated container system for your business.

Refrigeration Maintenance, Walk-In Coolers and Freezers

Most refrigerators and walk-ins seem virtually indestructible and problem free, but you'll get longer life out of yours by following these safety and maintenance tips. Clean the door gaskets and hinges regularly. The door gaskets, made of rubber, can rot more easily if they are caked with food or grime, which weakens their sealing properties. They can be safely cleaned with a solution of baking soda and warm water. Hinges can be rubbed with a bit of petroleum jelly to keep them working well. Dirty coils force the refrigerator to run hotter, which shortens the life of the compressor motor. They should be cleaned every 90 days, preferably with an industrial-strength vacuum cleaner.

Walk-in floors can be damp-mopped but should never be hosed out. Too much water can get into the seals between the floor panels and damage the insulation. A refrigerator only works as well as the air that's allowed to circulate around its contents. Cramming food containers together so there's not a spare inch of space around them doesn't help. Also try to keep containers (especially cardboard ones) from touching the walls of the cabinet. They may freeze and stick to the walls, damaging both product and wall. Use a good rotation system: First in, first out (FIFO) is preferable. Or put colored dots on food packages, a different color for each day of the week, so everyone in your kitchen knows how long each item has been in the fridge.


A walk-in cooler is just what its name implies: a cooler big enough to walk into. It can be as small as a closet or as large as a good-size room, but its primary purpose is to provide refrigerated storage for large quantities of food in a central area. Experts suggest that your operation needs a walk-in when its refrigeration needs exceed 80 cubic feet, or if you serve more than 250 meals per day. Once again, you'll need to determine how much you need to store, what sizes of containers the storage space must accommodate, and the maximum quantity of goods you'll want to have on hand. The only way to use walk-in space wisely is to equip it with shelves, organized in sections. Exactly how much square footage do you need? The easiest formula is to calculate 1 to 1.5 cubic feet of walk-in storage for every meal you serve per day. Another basic calculation: Take the total number of linear feet of shelving you've decided you will need (A), and divide it by the number of shelves (B) you can put in each section.

This will give you the number of linear feet per section (C). To this number (C), add 40 to 50 percent (1.40 or 1.50) to cover "overflow"-volume increases, wasted space, and bulky items or loose product. This will give you an estimate of the total linear footage (D) needed. However, linear footage is not enough. Because shelves are three dimensional, you must calculate square footage. So multiply (D) by the depth of each shelf (E) to obtain the total square footage amount (F). Finally, double the (F) figure, to compensate for aisle space. Roughly half of walk-in cooler space is aisle space. Another popular formula is to calculate that, for every 28 to 30 pounds of food you'll store, you will need 1 cubic foot of space. When you get that figure, multiply it by 2.5. (The factor 2.5 means only 40 percent of your walk-in will be used as storage space; the other 60 percent is aisles and space between products.)

The result is the size of the refrigerated storage area you will need. For a walk-in freezer, simply divide your walk-in refrigerator space by two. Larger kitchens, which serve more than 400 meals a day, may need as many as three walk-in refrigerators for different temperature needs: one for produce (41 degrees Fahrenheit), one for meats and fish (33 to 38 degrees Fahrenheit), and one for dairy products (32 to 41 degrees Fahrenheit). The walk-in is used most often to store bulk foods. Because this often means wheeling carts or dollies in and out, the floor should be level with the kitchen floor.

This leveling is achieved by the use of strips (called screeds) that are applied to the floor. Coolers don't come as a single unit; they are constructed on-site. The walls, ceilings, and floors are made of individual panels. Wall panels should be insulated to a rating of R-30, which means a 4-inch thickness. They come in various lengths and widths, with 12-by-12-inch corner panels at 90-degree angles. They can be as short as 71'2 feet or as tall as 131?2 feet. The most common type of insulation inside the panels is polyurethane, and the outside walls of the panels can be made of stainless steel, vinyl, or aluminum. Stainless steel is the most expensive, and aluminum-because it's the least expensive-is the most popular choice. If the walk-in is an outdoor installation, aluminum is the most weather resistant.

The installer will be sure the unit has interior lighting. The floor panels for walk-ins are similar to the wall panels. Load capacities of 600 pounds per square foot are the norm, but if you plan to store very heavy items (like beer kegs), a reinforced floor can be purchased with a load capacity of up to 1000 pounds per square foot. The refrigeration system of a walk-in is a more complex installation than a standard refrigerator, primarily because it's so much bigger. Matching the system (and its power requirements) with the dimensions of the walk-in and its projected use is best left to professionals, but it's important to note that a walk-in accessed frequently throughout the day will require a compressor with greater horsepower to maintain its interior temperature than one that is accessed seldom.

A 9-foot-square walk-in would need at least a 2-horsepower compressor. The condenser unit is located either on top of the walk-in (directly above the evaporator) or up to 25 feet away, with lines connecting it to the walk-in. The latter, for obvious reasons, is known as a remote system, and is necessary for larger-than-normal condensing units with capacities of up to 7.5 horsepower. In a remote system, the refrigerant must be added at the time of installation. For smaller walk-ins, there's also a plumbing configuration called a quick-couple system, which is shipped from the factory fully charged with refrigerant. This definitely simplifies installation. However, you may need the added power of a remote system if your kitchen has any of these drains on the walk-in's cooling ability: frequent door opening, glass display doors, multiple doors per compartment, or an ambient kitchen temperature that's near 90 degrees Fahrenheit.

Modern walk-ins sometimes offer a frozen-food section in addition to the regular cooler space. There are pros and cons to this concept. It may ease the load on the freezer, because it's already located inside a chilled airspace; but it also can't help but reduce overall usable space, because it requires a separate door. You can also order your walk-in with a separate, reach-in section that has its own door and shelves. Although this may save the cost of purchasing a separate reach-in, some critics claim that a walk-in is not designed to do a reach-in job, such as storing uncovered desserts. Do you really want them in the same environment as cartons of lettuce and other bulk storage items? There may be cleanliness or food quality factors to consider.

The doors should open out, not into the cooler itself. The standard door opening is 34 by 78 inches. Several door features are important for proper walk-in operation. These include: A heavy-duty door closer. Self-closing, cam-lift door hinges. If the door can be opened past a 90-degree angle, the cam will hold it open. A heavy-duty stainless steel threshold. This is installed over the galvanized channel of the door frame. A pull-type door handles, with both a cylinder door lock and room to use a separate padlock if necessary. Pressure-sensitive vents, which prevent vacuum buildup when opening and closing the door.

An interior safety release so no one can be (accidentally or otherwise) locked inside the cooler.
Other smart features that can be ordered for walk-ins are: A thermometer (designed for outdoor use, but mounted inside the cooler) with a range of 40 to 60 degrees Fahrenheit. A monitoring and recording system that keeps a printout of refrigeration temperature or downloads to a computer. Glass, full-length door panels (like those in supermarkets and convenience stores), sometimes called merchandising doors, either hinged or sliding. Heavy-duty plastic strip curtains inside the door. (One manufacturer claims a 40 percent energy savings with this feature.)

A foot treadle, which enables you to open the door by pressing on a pedal or lever with your foot when both hands are full. Three-way interior lighting, which can be turned on from outside or inside the cooler, with a light-on indicator light outside. Inside, the light itself should be a vapor-proof bulb with an unbreakable globe and shield. When space is at a premium, think about whether it is practical to install an outdoor walk-in unit. This is an economical way to add space without increasing the size of your kitchen, and you can purchase ready-to-use, stand-alone structures with electricity and refrigeration systems in place. They come in standard sizes from 8 to 12 feet wide and up to 50 feet in length, in 1-foot increments.

They range in height from 7.5 to 9.5 feet. Look for a unit with a slanted, weatherproof roof, a weather hood, and a fully insulated floor. Outdoor walk-ins cost about half of the price of installing an indoor kitchen walk-in, so this is a money-saving idea if it works in your location. If your demands for walk-in space are seasonal, consider leasing a refrigerated trailer, available in most metropolitan areas on a weekly or monthly basis. They can provide an instant 2000 cubic feet of additional storage space, which can be kept at any temperature from 40 to 80 degrees Fahrenheit. They use basic 60-amp, 230-volt, and three-phase electricity. Ask if the lease agreement includes hookup at your site and service if anything goes wrong.

Why is Refrigerant Leak Detection Necessary?

Experienced service technicians still find refrigerant leak detection in HVAC and RAC systems to be tedious and difficult because of the fact that a leak can be hidden from view by a component, tubing, or even an operating switch.

With the Environmental Protection Agency (EPA) regulation documented in The U.S. Clean Air Act (Sections 608 & 609), refrigerant leak detection takes on great urgency. Regulations are intended to lower greenhouse gas emissions which are very harmful to the environment. As such, the new government rules no longer give service technicians the option of adding refrigerant when the system is low due to a leak. Rather, the leak has to be found and fixed within a specified period of time.

There are numerous types of testing equipment that can be used in refrigerant leak detection, some of it automated and others acting as sniffers for onsite testing. To find the leak, service technicians have to determine the best method to use. Methods include a soap solution, a halide torch, dye interception, isolation of a component from the system, or pressurizing the system with dry nitrogen gas.

All of these methods take time and money, which can turn into a very expensive service call. A less costly alternative for companies is utilizing refrigerant management software that pinpoints the origin of a leak by either tracking service events over time to establish trends or to implement an automated leak detection technology.

One of the fastest methods which can be used in refrigerant leak detection is an electronic leak detector. These types of detectors can find leaks of hydro fluorocarbons (HFCs) and chlorofluorocarbons (CFCs). Quick identification of a leak is important because the release of these gases is heavily regulated by the EPA, with companies subject to fines if their emissions are not fixed within a certain time frame.

There is refrigerant gas management software which can help in the detection of refrigerant leaks. It provides companies with exact details on what their refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC) systems are venting, tracks performance, monitors and detects refrigerant gas leaks, provides refrigerant usage reports, and keeps accurate records on maintenance and service.

Regulations on refrigerant leak detection describe and govern the proper repair of a leak and appropriate disposal of any refrigerant system which can't be repaired. These extensive requirements are in force in the United States, as well as several foreign countries. The treaties set forth a worldwide response to improving and protecting the planet.

Quick action of refrigerant leak detection is a great importance to the environment. Refrigerant contains gases that have been identified as damaging to the ozone layer and show a high potential for causing global warming. To comply with environmental standards, many companies are investing in a refrigerant management program to monitor and track equipment usage.

Because of environmental and cost concerns related to refrigerant leak detection, many facilities with systems that use refrigerants are relying on refrigerant tracker applications. A refrigerant tracker monitors refrigeration and air-conditioning (RAC) systems and heating, ventilation and air conditioning (HVAC) systems around the clock and instantly detects the location of any leaks. Various studies confirm that industrial and commercial facilities will be able to save money every year by using leak detection monitoring systems.

Tips to Choose the Perfect Commercial Refrigeration System

Do you run a restaurant business? The reason behind the success of your establishment is the quality of food and beverages available at your restaurant. Serving cold and stale food will land you in deep trouble. The drinks also need to be cool and refreshing. You need to store the food items and beverages properly. Only commercial refrigeration system can help you to achieve this. Before you decide to make a purchase, keep these points in mind:

* Consider the size of the refrigerator first. Do you find it hard to store all the essential items in your present freezer? Commercial refrigerators are usually bigger in size where you can store enormous quantities of items. If you want to store a large number of frozen products, beverages, and other food items, make sure that it has the required number of shelves, proper adjustment system, and a good storage capacity.

* You also need to consider the space where you want to install it. If your restaurant kitchen is small, then there is no use of buying a commercial freezer that will occupy most of the space. Buy the refrigerator after considering the space available for installation.

* When purchasing commercial refrigeration, it is good to buy one made of stainless steel. Though they are little expensive but it will be beneficial to you in many ways. For example, they are durable and will save your money in the long run. Stainless steel refrigerators are also easy to clean. Most hotels, bars, restaurants, and supermarkets use stainless steel commercial refrigeration systems because of this reason.

* There are many companies in the market that deal with commercial refrigeration systems. It is always good to do some research before you buy. This will help you to know the different models and sizes of commercial refrigerator, and you will be able to know their market price so that you don't have to pay extra.
