Walk-In Costs

*These numbers were figured using the $.0999 kilowatt hour cost. According to the Energy Information Administration this is the average cost in the United States for commercial electricity.

  1. This chart was created using several assumptions that can affect your actual operating cost.
    The type of insulation in the walk-in
  2. Efficiency of the refrigeration system.
  3. Inside and outside temperature of walk-in.
  4. Where the walk-in is located.
  5. the temperature and the weight of the product entering the walk-in.
  6. How often the door is opened.
  7. The age of the walk-in.
  8. Cost of electricity

This is just to name a few. Actually over a hundred factors are considered when sizing refrigeration systems for a walk in. Most walk-ins are designed to run 80% of the time or between 16 and 18 hours per day. For more information on this topic and a more accurate estimate, view our operating cost article.

Most users do not understand that they can lower the cost of operating their units if they do some very simple things. First, if initial costs are not an issue, purchase your walk-in cooler or freezer with polyurethane insulation. It is one of the best insulations in the market for walk-in coolers or freezers. Next, do some simple things such as order your walk-in with strip curtains to lower heat gain to the walk-in when loading or walking into the unit. You need to work with your refrigeration service technician to set the minimum required defrost cycles for your specific needs. Step inside the walk-in once a month and check for any light coming from around the door, refrigeration systems, electrical connections and other penetrations in the panels. If light is found, contact your local service technicians to correct the issue. Periodically check door gaskets and door sweeps for wear. If wear is evident have your dealers replace the worn part. Have regular maintenance of the refrigeration system by a licensed refrigeration technician.

International Coolers has a nation-wide service network to service their walk-ins and refrigeration systems. Call your in-house sales representative for the service dealer near you.

International Coolers believes that walk-in coolers and walk-in freezers are a must in the many markets we service. Most walk ins are purchased because they are necessary to the success of the business they serve. That is why most walk ins are not purchased emotionally but logically. Most customers purchase a walk-in wanting a certain level of quality then they look for the lowest price they can get. International Coolers has always provided the best quality walk-ins at the most reasonable pricing in the industry. You will not find a better value in any other walk in produced today. We may not always be the cheapest but at the level of quality you need in your application, you will not find a better buy.

We weigh each walk-in before shipment to get the exact weight. But you can figure an estimated weight by taking the surface square footage of the walls and ceiling times 2.4, then add the floor surface square footage if included times 3.15 add these two numbers to 220 pounds for the door and you will get an estimate of the walk-in weight. Add 130 pounds to this weight for an 8’6″ pallet and you will get an estimate shipping weight.

All International Coolers walk-in drawing are kept on file for future expansion or repair. All that is needed is the International Coolers job number for the walk-in. International Coolers customer service personnel can help you find this number.

International Coolers offers many types of the surface skins on the walk-ins we sell. The types carried at this time are the following:

  1. G90 26 gauge, stucco embossed galvanized. This skin is used for interior and exterior walls, ceilings and exterior floors.
  2. G90 26 gauge, stucco embossed galvalume. This skin is used for interior and exterior walls, ceilings and exterior floors.
  3. G90 26 gauge, stucco embossed white galvanized. Used for interior and exterior walls, ceilings and exterior floors.
  4. 24 Gauge stainless steel polished 3B. Used for interior and exterior walls, ceilings and exterior floors.
  5. 22 Gauge stainless steel 2B brushed. Used for standard interior floors.
  6. G90 20 gauge flat galvanized. Used on non-NSF floors

Coolers can be installed on ground contact concrete floors and pads but it is recommended that an insulation barrier be installed under the walls of the unit to reduce condensation on high humidity days. On coolers located on wood frame floors a cooler floor is necessity. Condensation will develop under the floor and eventually rot the floor out. On freezers, a floor or an insulated concrete floor with insulation barrier is required. Check local codes or contact an architect for concrete insulated floor plans for your area.

Doors and floors are the most used and abused parts of a walk in cooler or freezer. Standard floors are designed with a 600-LB load per square foot. That sounds like a lot of load carrying ability until it is considered that a 200-LB load on a two-wheel cart can develop a load of 50-lbs per square inch or 7,200-lbs per square foot. Usually when a ramp is requested, it is assumed that two-wheel carts carrying heavy loads will be used in the walk in. Due to this factor, International Coolers will only provide ramps with reinforced floors.

All International Coolers walk-ins are test assembled in our plant before shipment to assure that all the panels and parts fit nicely together and meet our stringent quality standards. We provide a layout drawing with each panel labeled and an installation manual with pictures to assist in easy assembly. The walk in will go together better than any other walk in on the market. Most installation problems, if any, have to do with site preparation. Taking your time and following instructions any person should be able to install an International Coolers walk-in.

Almost all non-warehouse walk ins are delivered knocked down and come with the panels equipped with cam-action locking devices. These cam-lock locking devices allow the panels to be locked together to assemble the walk in.

The cam-locks are designed as male and female versions. The male cam-lock has a hook and the female cam-lock has a pin. When the right angle hex shaped cam wrench is inserted in the male cam-lock hole and turned in a clockwise fashion the hook reaches out inserting itself into the female cam-lock and catches the pin. Once the pin stops the hook from turning, the cam action of the male lock kicks in and draws the hook toward the male cam-lock. This causes the panel edged to compress squeezing the gasket and providing an air tight seal.

These locking devices come mostly in two forms. In foamed-in-place walk in the cam locks have fins that, when the panel is foamed in place, are held by the foam, which forms around the cam lock. Only the foam in the panel holds these types of cam-locks. The other type of cam-lock is a block panel fastener. These types of cam-locks are held in a strong plastic holder that is held in place by the foam and the metal skins of the walk in. International Coolers not only uses these types of cam-locks but also has them foamed-in-place to add further insulation.

Many people think it would be cheaper to build their own walk-in but find that once they add up the cost it can be like building your own car from scratch. Also, the local health departments may have issues with the walk in not meeting health regulations for cleanable radiuses and surfaces. It is a bad day when the health department tells you, you can’t use the walk in you built for your business because it does not meet minimum health standards

R-value is the resistance to heat flow. The higher the R-value the better the insulation is in a walk-in cooler or freezer. K-factor is the ability of heat to flow. The lower K-factor, the better for walk-in coolers or freezers.

R-value of any insulation varies according to age of the insulation, wetness of the insulation, type of insulation, mean temperature of the insulation and condition of the insulation.

Most companies publish the R-values of their walk-in coolers and freezers. These R-values are usually taken at the time the insulation is produced rather than what the R-value is after the unit has been in the field for one year. In the roofing industry manufactures publish a 90-120 day aged R-value at a 75° mean temperature. Even these R-values do not take into consideration the moisture content of the insulation, which can lower R-value by as much as 75%. It also does not take into account that your walk-in will operate at a much lower mean temperature.

When buying a walk-in cooler or freezer ask what the aged R-value of the insulation will be at your mean operating temperature, 5 years after manufactured and how resistant to moisture the insulation is. You will be surprised how these numbers vary from their published R-values.


International Coolers uses polyurethane insulations in our walk-in coolers and freezers today;  foamed polyurethane. International Coolers or its dealers will be happy to supply you with the correct insulation for your specific needs.

International Coolers manufactures walk-ins uses polyurethane insulation; Using this allows our company to manufacturer each walk-in with the correct insulation that best suites the customer’s needs. Since we believe that foamed-in-place polyurethane is a good insulation when it is used not only to insulate but used in an item that has many parts that need to be molded together, we use it to manufacturer our cooler and freezer doors. For cooler and freezer walls, ceilings and floors we use polyurethane.

It is always better not to include wood in walk-in coolers and freezers. Wood is a poor insulator and does not do well in the consistently damp or wet environments commonly found in walk in coolers and freezers. Some walk in manufactures actually use 2X4-inch tongue and grove edging around each panel edge throughout their walk ins. Some walk in companies use wood throughout their walk in doors. International Coolers uses no wood products in our standard walk in walls, ceilings, doors, or floors. We do use 3/4 inch plywood in our optional extra strength floors and some custom built doors.

First of all, wood is not a good insulator. Second, wood absorbs moisture. In a freezer it can then freeze and swell causing the joints to misshape and leak precious cold. Third, damp wood is a food source for mold and can cause mold to grow inside the panel and possibly cause negative health affects. Finally, wood can absorb water vapor lowering its already low R-value. This water vapor, through freeze and thaw cycles, causes water to run down and either freeze inside the walk in or run outside the walk in causing an unsafe slippery floor increasing injuries and liability issues. Therefore wood is not desirable in walk ins.

Most walk in manufacturers would say that their major customer service issue is shipping damage. Walk ins by nature are somewhat fragile when pitted against a raging forklift or crazy two-wheel cart. International Coolers  has engineered a shipping system that all but eliminates the normal damage seen by our competitors. A pallet is provided as a shipping base for each walk in. Packaging foam is installed between each panel and on long hauls plywood is installed around the outer sides of the pallet. Then everything is wrapped in plastic and marked fragile for shipping. Also we try to eliminate transfers from trucking company to trucking company to reduce transfer problems. Overall, International Coolers does all it can to see that the product arrives at your location in the quality shape that it left our plant.

Delivery is always dependent on the location that is receiving the shipment and where the shipper is located. International Coolers is located in the center of the country so the entire United States is accessible in a very reasonable ship time. Most of our orders are next day shipments meaning that if your walk-in ships today you will receive it tomorrow. Other areas take a little longer but are always within ten days of shipment. International Coolers consistently negotiates with carriers to receive the best rates, quality control and quickest delivery possible.

Dealers can call your International Coolers representative to get your tracking number or you may go to our order status page, fill out the info and get your tracking number and a link to check its location.

Go to the order status page and type in dealer telephone number and job number. You will go to your order page. There you will be able to select pro number and shipper for your order. Once you have the pro number and shipper you can call the shipper to track your order.

To reduce damage most International Coolers walk ins are shipped skidded on a skid. Once it is at your site it will need to be unloaded with a forklift or the unit will have to be unloaded off the skid piece by piece from inside the truck. This is a three to four man job not counting the trucker. Time is a consideration as some trucking companies’ charge extra for extra long unloading times.

Very. NSF stands for National Sanitation Foundation and is looked upon as the ultimate foodservice design and equipment listing agency by the local building and health departments. In many states and counties if it does not have the NSF seal it is not allowed for public use.

UL stands for Underwriter Laboratories and is well known in both the foodservice and building industries as a testing laboratory of products and materials. You will find a UL sticker on all UL tested products. This sticker will show their test results on varying items or show that it meets UL standards. Many building code professionals look for this sticker when approving electrical compliance.
