ComStar Refrigerants

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 and HFC 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 systems for their cooling potential & consistent performance. However, these solutions have very damaging impacts to ozone depletion & global warming contribution.
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These alternative refrigerants make it easy to replace harmful and outdated chemistry used in HVAC systems like R-22 and R-404.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.

Very Low Glide -  No Required Oil or System Changes - Lowest Global Warming Potential Replacements (GWP) -  Applicable for Both Low & Medium Temperature Requirements

RS-44b Performance Refrigerant

ComStar's RS-44b is the next generation Drop-in Replacement for R-22 gas in all applications with a significantly lower global warming potential (GWP) and zero ozone depletion potential (ODP).
  • Drop-In Performance - No Oil, System or Component Change Required 
  • Compatible with Mineral (MO), Alkyl Benzene (AB) and Polyol Ester (POE) Based Lubricants 
  • Non-flammable & Low Toxicity Performance
Common applications include, but not limited to: 
Heating, Ventilation & Air Conditioning (HVAC), Commercial & Industrial Refrigeration, Chillers, Beer & Wine Cellars, Cold Stores, Refrigerated Transport, Supermarket Displays & Appliances, Dairy Chillers, and Much More. 

RS-45 Performance Refrigerant 

ComStar's RS-45 is the ideal, drop-in replacement for R-22 gas in flooded chiller systems.  Reduce the environmental impact with this Zero-ODP and Low-GWP refrigerant technology.
  • Drop-in Replacement for R-22 - No Oil, System, or Component Change Required 
  • Low Glide Performance Equivalent to R-22
  • Non-Flammable & Low Toxicity Performance

Common applications include, but are not limited to: 
Medium & Low Temperature Applications and Chillers with Flooded Evaporators

RS-50 Performance Refrigerant 

ComStar’s RS-50 is an eco-friendly replacement for R-404A and R-507 with higher energy efficiency and cuts the global warming potential (GWP) in half compared to R-404A or R-507. Mass flow is equivalent to R-22 and considerably less than R-404A or R507.
  • Non-ozone depleting and non-flammable
  • Replaces R-22 refrigerant gas in medium & low temp refrigeration applications
  • Compatible with POE lubricants commonly used with R404A
Common applications include, but are not limited to:
Supermarket display cases, AC refrigerant, cold stores, freezers, refrigerated transport, ice machines, cold storage, beer cellars, freeze dryers & environmental test chambers.
