R454b refrigerant

R454b is the lowest GWP replacement for R410a (78% reduction) which provides similar capacity and efficiency and offers similar properties to R410a

OVERVIEW

Direct replacement for R410a-designed systems

Refrigerant R454b is a mildly flammable low global warming potential (GWP) hydrofluoroolefin-based refrigerant to replace R410A in new equipment designs. It offers the optimal balance of properties to replace R410a in direct expansion air conditioning, chiller, and heat pump applications.

 

R454b offers similar properties to R410a which makes it easy and cost-effective to apply in new equipment without major modifications.
