Genetron® 407C

A long-term, non-ozone depleting replacement for R-22 in various air-conditioning applications as well as in positive displacement refrigeration systems. For new equipment and retrofits. Not recommended for use in chillers with a flooded evaporator.

General Information

  • ASHRAE #R-407C
  • ClassHFC
  • Refrigerant TypeBlend
  • Typical LubricantPOE
  • SubstitutesHCFC-22
  • ContainsHFC-32 (23%), HFC-125 (25%), HFC-134a (52%)
  • GlideHigh
  • NotesCommercial Refrigeration: Reasonable performance match to R-22 in medium temperature refrigeration. Lower capacity in low temperature refrigeration systems. Air Conditioning and Heat Pumps: Best retrofit alternative to R-22. Close performance match with slightly higher operating pressures.
