Freon™ 95 refrigerant

Freon™ 95, a PFC-based refrigerant, is the industry standard replacement for R-13 and R-503 in very low temperature applications [below -40°F to -150°F (-40°C to -101°C)] such as medical freezers and environmental chambers.  It offers advantages over R-23, including significantly lower compressor discharge temperatures, making it the best choice to ensure optimum systems reliability for critical applications.  Freon™ 95 can be used in new equipment and can also be used to retrofit existing systems.


R-508B; A1 Safety Classification


R-13, R-23, and R-503


  • Very low temperature [below -40°F to -150°F (-40°C to -101°C)]:
    • medical freezers
    • environmental chambers


  • Endorsed by many OEMs.
  • Longer equipment life: Lower discharge temperature than R-23, increases compressor service life.
  • Increased cooling capacity: 30% greater cooling capacity than R-13.
  • Best match for R-503.
