Important features of walk-in coolers and commercial freezers

What sizes of walk-in coolers are available?

Coolers take up a good bit of room, so it’s important to find one that fits your space. Most cooler distributors have selections of pre-built coolers for sale, and if none of these fit your needs, you can always consider custom models.

  • Pre-made builds: Some walk-in cooler distributors have pre-made models for sale in their most requested sizes. Coolers that are 7 feet by 8 feet by 7 feet, for instance, are popular choices for residential walk-ins. Because they often have these sizes in stock, these coolers generally ship more quickly than custom orders.
  • Custom builds: If no pre-made cooler fits your size needs, you can order a custom-built cooler. Custom builds may be more expensive than pre-made models, and they usually take longer to ship.
  • Modular coolers: If you need a large walk-in cooler, you may want to consider a modular cooler. These walk-ins are built from panels that fit together to form coolers of various sizes, making them ideal for customers who need large coolers or refrigerated warehouses.

What kind of doors do I need?

Both walk-in coolers and commercial freezers need doors that seal in cool air to keep the refrigeration process running efficiently. If you plan on using your cooler to sell merchandise, you also need doors that display those products clearly without losing cool air.

  • Door seals: The most important part of any freezer door is its seal. Most coolers feature a layer of rubber between the door and the cooler body to create an airtight seal. Walk-in coolers (and some commercial freezers) are outfitted with locks and levers to put more pressure on the seal and minimize air leaks.
  • Display door options: Walk-ins and commercial freezers usually have stainless steel doors, but commercial display coolers designed to sell merchandise are outfitted with clear glass. This glass is built to trap cool air; however, they are not quite as insulated as steel doors. Some merchandise coolers also use plastic strip curtains that allow customers to reach into the cooler without opening a door.

What type of insulation do I need for my walk-in cooler?

A cooler can’t trap cold air unless it is properly insulated. Insulation’s effectiveness is evaluated by its R-value, a unit that measures its resistance to heat flow. The higher the R-value, the better insulated the cooler is. Currently, cooler insulation requires an industry standard minimum R-value of 25.

  • Polyurethane: Polyurethane is a standard insulation for freezers that, on average, has an R-value of 30-32. This type of insulation is best for freezers.
  • Extruded polystyrene: Though it does not have as high an R-value as polyurethane, extruded polystyrene is an insulation material designed to work in relatively high-moisture environments. Extruded polystyrene is best for coolers.
  • Thickness: On average, insulation is about 4 inches thick, though some manufacturers may be able to produce thicker insulation for custom orders. The insulation is surrounded by plates, usually made of steel or fiberglass, to keep it in place.

Should I buy a steel or fiberglass cooler?

Most coolers are made of either steel or fiberglass. Each material has different benefits, though options may be limited depending on the type of cooler you want.

  • Steel: Most coolers, both commercial coolers/freezers and walk-ins, are made of steel. Steel is durable and weather resistant, though it is susceptible to rust and corrosion. Steel coolers are often built in segments and must be put together and sealed.
  • Fiberglass: Fiberglass coolers are more weather-resistant than steel coolers, but they are harder to repair. Some fiberglass walk-in coolers can be made of single units, minimizing gaps in construction and air leaks.

What accessories are available for walk-in coolers?

Walk-in coolers can be customized with added accessories. Depending on the cooler’s use, some accessories may be more integral than others.

  • Shelves: Most walk-in coolers will need some shelves for food or item storage.
  • Strip curtains: Strip curtains can provide a cheap way to partition the cooler. This setup is helpful if you are storing different types of food or materials that need to be kept separate.
  • Hooks: If you plan on using your cooler as a game locker or for meat storage, hanging meat hooks are a great solution to keep meat from spoiling before it is processed.

What type of flooring do I need in my cooler?

If you’re purchasing a cooler, you do not want to overlook the importance of flooring. Making sure the flooring fits your needs is a fundamental consideration when buying a cooler.

  • Wear and weight: If your cooler gets a lot of foot traffic, you will want a floor that is fairly durable and won’t wear out. You also want to make sure the floor will support the weight of the material you’re storing. Cheaper tile tends to wear more quickly than heavier plating, but heavier plating is more expensive.
  • Traction: Installing non-skid surfaces like tread plates can give you better traction in the cooler. These surfaces are most useful in coolers that store meat or materials that can drip and make floors slippery.
  • Ramps: If you’re storing heavy goods like kegs, you may want to invest in an exterior ramp that makes transporting goods on dollies or hand trucks easier.
