6 Benefits of a CO2/NH3 Cascade System

CO₂/NH₃ cascade systems offer food processors a practical way to increase efficiency. By using two centralized refrigeration systems working in unison to provide cooling temperatures, they maximize the effect of carbon dioxide and ammonia. The high-temperature system pulls heat away from the low-temperature system, which in turn uses recirculated liquid to cool the evaporators.

Cascade systems that use CO2 as a secondary refrigerant offer unique advantages. Carbon dioxide is nontoxic and nonflammable, and is also less likely to damage food products in the event of a release. For food plant owners, CO2/NH3 cascade systems offer six key benefits, which are detailed below.
