    ComStar Refrigerants

    Refrigerant technology has come a long way in the last 20 years — advancements in chemistry and dedicated focus on reducing global warming potential have shifted and phased out harmful HCFC, HFC, and CFC based refrigeration technologies.  The ComStar line of performance refrigerants easily replace R22 and R404a in a wide variety of applications with a significantly lower environmental impact.

The Trouble with Legacy Refrigerants & HCFCs

Traditional solutions like R-22 and other common refrigerants like HCFC, HFC, and CFC based gas chemistries have been used for decades in commercial & industrial air conditioning (AC) systems for their cooling potential & consistent performance. However, these solutions have very damaging impacts like depleting the ozone layer & contributing to global warming.
 
Governmental regulations and phase out restrictions are in place to limit the damage done to the ozone layer and mandates are in place for low GWP alternative refrigerants.  In fact, the EPA has instituted heavy regulations that have completely restricted R22 refrigerant supplies to prevent damaging potential refrigerant leaks. Maintain cooling performance and consistency and make the switch to ComStar refrigerants.

ComStar Refrigerants - RS Series

These alternative refrigerants make it easy to replace harmful and outdated chemistry used in HVAC systems like R-22 and R-404.  Browse the solutions portfolio by performance characteristics and common applications below.  View the full ComStar Refrigerants Portfolio Here ►

The ComStar Refrigerants offer the air conditioning industry a low GWP solution with all grades offering zero ozone depletion potential (ODP) for greater peace of mind.  All grades within the RS Series of alternative refrigerants provide compatibility with legacy lubricants like Alkyl Benzene, Mineral Oil & Polyol Esters (AB/MO/POE) without a required unit switch-out. Simplifying the recharge of a variety of air conditioning units with fresh refrigerant lines for long-term heat management.
