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:
- Low operating costs
- Low capital costs
- Ammonia charge reduction
- Reduced compliance costs
- Constant positive pressure
- Quality and throughput improvements
We’ve designed and installed 10 cascade CO2 systems to date, and even engineered the world’s largest CO2 and ammonia cascade system for a 365,000-square-foot food processing facility.
