R-437A


Replaces

R-12, R-413A, HCFC-containing blends (e.g. MP39, MP66, R-409A)


Applications

  • Automotive AC systems designed for R-12
  • Refrigeration systems designed for R-12, including:
    • food service
    • supermarket display cases
    • food storage and processing
    • domestic refrigerators/freezers 


Benefits

  • Provides cost-effective retrofits
  • Non-ozone-depleting HFC retrofit refrigerant
  • Compatible with traditional lubricants - In most cases, no change of lubricant type is needed
  • Enables continued use of existing equipment
  • ASHRAE safety classification of A1 (refer to AS-1 bulletin and MSDS)


Performance

  • Provides up to 10% better cooling capacity vs. R-12
  • Provides similar to slightly lower energy efficiency vs. R-12
  • Lower discharge temperature vs. R-12


Lubricant Recommendation

For R-12 automotive air conditioning systems, Freon™ MO49Plus™ is compatible with mineral oil in existing R-12 systems. In most cases, no change of lubricant type during retrofit is needed.

For R-12 stationary medium-temperature refrigeration and air conditioning systems, Freon™ MO49Plus™ is compatible with traditional and new lubricants – mineral oil, alkylbenzene, and polyol ester. In most cases, no change of lubricant type during retrofit is needed. Refer to Freon™ MO49Plus™ Retrofit Guidelines for more details.
