Creard R-455A

Creard R-455A is an A2L Low GWP refrigerant for low and medium temperature applications formerly covered by R-404A or R-507. Its low GWP below 150 makes it a long-term solution compliant to the EU F-Gas regulation.

Applications

  • Long-term replacement for R-404A / R-507 and R-22
  • Cold storage cells
  • Supermarket multiplex systems and display cases
  • Ice machines
  • Transport refrigeration
  • Condensing units, chillers

Properties

  • Low global warming potential (GWP100 below 150)
  • Comparable thermos-physical properties to R-404A / R-507 and R-22
  • Low flammability profile, non-toxic
