CO2 Refrigeration System for the V-21

Go GREEN and help save the Ozone Layer!

Liquid carbon dioxide (R744), the environmentally-friendly refrigerant of the future, operates more efficiently than industry standard R134a refrigerant (see table below) and is non-ozone depleting, non-toxic, and non-flammable.

  • Refrigeration unit contains R744 (carbon dioxide).
  • Does NOT deplete the Ozone layer.
  • Reduces risk of Global Warming (GWP = 1).
  • The CO2 refer deck is a direct alternative to the R134a refer deck - both units are installed and operate the same way.

R744 (CO2) Refrigerant vs. R134a Refrigerant over 100 years:
