WebJan 26, 2024 · Each system of a cascade system uses a different refrigerant that is most suitable for the given temperature range. High temperature systems use high boiling point refrigerants such as R-404A, R-507A, R-134A, propane, butane, and ammonia, whereas low temperature systems use low boiling refrigerants such as R-744 (CO 2) and R-508B. WebUsing an HFC-based refrigerant such as R404A for example, would cost $8 per pound (newer HFO refrigerants such as R448/449 can be as high as $12 per pound). But CO 2 refrigerant by contrast costs around just $1 per pound. Using CO 2 instead saved that store $10,000. CO2 ROI Summary.
