Walk-in coolers are convenient and energy-efficient ways to store perishable inventory and keep it at the right temperature. To maintain the desired temperature, walk-in coolers and freezers must have strong, durable, and reliable insulation. Depending on the type of food being stored, walk-ins may require different types of insulation, but all must be able to withstand frequent use and last for years. One of the most common materials is stainless steel, used for most walk-in construction. It is an excellent conductor of heat and electricity, making it an ideal choice for a walk-in cooler’s construction. Other materials that are common in walk-in coolers include plastic and aluminum. Many walk-in coolers offer climate control for precise temperature settings that can be set to fit the needs of your product. Some models offer humidity control for foods like fruits and vegetables or sealed products like wine. Walk-in coolers are available in sizes ranging from 10 to 150 cubic feet. Most walk-in coolers have a lift-gate delivery option.
