A walk-in refrigerator is a large, insulated storage space designed to keep perishable items at low temperatures. It allows easy access for employees to store and retrieve food products, making it ideal for restaurants, grocery stores, and warehouses. These units can vary in size and are often customized to fit specific needs. Typically, a walk-in refrigerator operates using a refrigeration system that maintains a consistent temperature, usually between 32°F and 40°F (0°C to 4°C). They are equipped with shelves and racks to organize items efficiently, ensuring that food safety standards are met while maximizing storage capacity.
