Cooling tunnels ensure controlled temperature reduction in both batch and continuous process systems. They are similar to air convention ovens, but have no heating capacity.
Industrial cooling systems and industrial cooling equipment includes air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers; ducts and/or pipes; and other devices for removing heat from a system that contains a heat source.
Industrial refrigerators are designed to maintain stored items below room temperature, but above the freezing point of water. Industrial freezers are designed to keep their contents below the freezing point of water (32 degrees Fahrenheit).
