Environmentally Friendly Subcritical Refrigeration System
Zero Zone, Inc., North Prairie, Wis., introduced the ColdLoop CO2 Subcritical refrigeration system, designed to cool food display cases and walk-in coolers and freezers without being harmful to the environment.
The new ColdLoop CO2 Subcritical System minimizes the use of HFC refrigerants in favor of CO2, a readily available refrigerant that has a GWP (global warming potential) of 1—the lowest GWP available—and is considered the baseline by which all other greenhouse gases are measured, according to the U.S. Environmental Protection Agency.
