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
Features:- 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.
