R423A (FREON™ 39TC)

R423A is an easy to use, non-ozone depleting HFC retrofit refrigerant blend of R134a and R227ea developed to replace R12 in centrifugal chillers.  It provides similar cooling capacity and comparable energy efficiency when compared to R12, with similar discharge pressures and temperatures. 

R423A provides a quick, easy and cost effective retrofit typically requiring a single lubricant change to Polyol Ester without the need for flushing.  It avoids the expensive engineering changes required to convert existing chiller equipment to R134a.  This product can be topped up during service without removing the entire refrigerant charge.  As R423A is a blend, it should always be removed from the cylinder as a liquid when charging the system.

APPLICATIONS:  Centrifugal chillers
GWP:  2280
