• R507A

    Pentafluoroethane/Trifluoroethane (R507A)

    CAS No.:354-33-6/420-46-2 UN No.: 3163 CLASS No.: 2.2 Molecular formula: CHF2CF3/CH3CF3

    R507A is blended by R143a and R125, which can be used to replace R502 and is suitable for large commercial air conditioners, refrigerated trucks, etc.

  • R507A

    R507 is an azeotropic refrigerant blend consisting of 50% R125 (CAS 354-33-6) and 50% R143a (CAS 420-46-2). It was developed as a replacement for R502 and R22 in commercial refrigeration applications. R507 has zero ozone depletion potential (ODP) and is classified as an A1 refrigerant (lower toxicity, no flame propagation).
