CO2 Cascade Rack System
Natural, Efficient, and Future-Proof Refrigeration
Product Details
A Natural Refrigerant Solution
Hussmann’s cascade rack is a low temperature subcritical direct expansion refrigeration solution using CO2, a naturally occurring refrigerant. The use of CO2 as a refrigerant reduces the HFC charge with a minimal impact on energy efficiency to reduce the carbon footprint of the system.
Unlike CO2 secondary or liquid recirculation systems, cascade CO2 systems use a vapor compression cycle similar to traditional direct expansion systems. Instead of condensing against ambient air or water, the CO2 condenses against a primary refrigerant.
