Product Overview

RS-44b is an all-purpose, low GWP & zero ODP refrigerant solution and direct R22 Drop-in Replacement. The RS-44b is a true drop-in technology to replace the phased out R22 technology under ASHRAE number R453A.

RS-44b refrigerant provides the closest drop-in replacement for R22 with equivalent performance in:
Mass Flow Rate, Discharge Pressure, Energy Efficiency and Cooling Capacity

RS-44b provides superior performance compared to R22 for:
Global Warming Potential (1664 TAR), Lower Discharge Temperature, Nonflammable, Zero Ozone Depleting Potential (ODP).
