Cascade CO2/NH3 Refrigeration
A Sustainable Refrigerating System
Food processors and distributors are under constant pressure to produce more while spending less on operations. For plant owners looking for greener and more efficient secondary refrigerants, a carbon dioxide (CO2)/ammonia (NH3) cascade system is a viable option. In addition to providing 0 ozone depletion potential (ODP) and 1 global warming potential (GWP), CO2/NH3 cascade systems offer several benefits for food processing and low-temp distribution facilities including:
Lower operating costs
Ammonia charge reduction
Constant positive pressure
Quality and throughput improvements
Frozen foods processors often seek lower process freezing temperatures to enable faster freezing, which optimizes food quality and enables increased throughput. With CO2/NH3 cascade systems, lower temperatures (and higher production yields) are achievable with less investment and less operating costs than conventional refrigeration systems.
