A cold cabinet, also known as a CHILLER, is a type of refrigeration unit used to store food and other items at a low temperature. It is typically used in commercial kitchens, restaurants, and other food-related businesses. The term 'CHILLER' is derived from the fact that it keeps items cool, usually below 40 degrees Fahrenheit. Cold cabinets are designed to maintain a consistent temperature and humidity level, ensuring that food and other items remain safe and fresh.
