Freon™ 39TC is a non-ozone-depleting HFC retrofit refrigerant for R-12 in centrifugal chillers.

» Freon™ 39TC Case Histories


R-423A; A1 Safety Classification




  • Centrifugal chillers designed for R-12 


  • Provides quick, cost-effective retrofit
  • Non-ozone-depleting HFC
  • Retrofit typically requires a single lubricant change to polyol ester (POE) without additional flushing
  • Avoids expensive engineering changes to existing chiller equipment
  • Enables cost-effective continued use of existing chiller equipment
  • Can be topped off during service without removing the entire refrigerant charge


  • Provides required cooling capacity and comparable energy efficiency vs. R-12
  • Similar discharge temperature and pressure vs. R-12

Phaseout Schedule 
Freon™ 39TC is a zero ozone-depleting substance (ODS) and, therefore, is not subject to phaseout under the Montreal Protocol regulations.


Lubricant Recommendation
For most systems, only one lubricant change to POE during retrofit is required.  Freon™ 39TC tolerates high residual levels of mineral oil in POE, and therefore, no system flushing is required after changing the original lubricant to POE. Refer to the Freon™ 39TC Retrofit Guidelines for more details.
