Honeywell Genetron® 422D Refrigerant
Categories: Fluid

Material Notes: Genetron® 422D is a non-ozone-depleting HFC based refrigerant for replacement of HCFC-22 in low– and medium–temperature refrigeration systems. Genetron 422D is a blend refrigerant suitable for direct expansion evaporators. It should not be used in systems that employ flooded evaporators.

Applications: Examples of low– and medium–temperature commercial refrigeration applications include:

  • Supermarket display cases
  • Food preservation and food processing
  • Ice machines
  • Can replace HCFC-22 in many cases without having to change compressor lubricant.
  • May be used with alkyl benzene (AB), mineral oil (MO), and polyolester (POE) lubricants. If inadequate oil return is observed for AB or MO, addition of POE may be needed.
  • Genetron 422D can, in most cases, be used with existing HCFC-22 thermostatic expansion valves. Larger valves may be needed in cases where the R-22 valve is near its maximum capacity.
  • Lower discharge temperature than HCFC-22 which may extend compressor longevity.
  • Non-ozone-depleting HFC refrigerant.
  • ASHRAE classification A1 (low toxicity, non-flammable per ASTM E-681 method).
  • Allows for use of existing equipment.
