A walk-in cooler is a large refrigeration unit designed to store perishable items at low temperatures. It is commonly used in commercial settings like restaurants, grocery stores, and warehouses. The cooler allows employees to walk inside to access and organize food products, ensuring they remain fresh and safe for consumption. These coolers typically maintain temperatures between 32°F and 50°F (0°C to 10°C) and can be customized in size and layout. They are equipped with shelves and racks for efficient storage and often feature insulated walls to minimize energy consumption. Proper maintenance is essential for optimal performance and food safety.
