Refrigerant - R404A

• HFC
• Substitute for CFC R502
• Zeotropic refrigerant containing R125,
• R143a and R134a (44/52/4% by weight)
• Refrigerant must be
• charged from liquid phase
• Physical and thermodynamic
• properties comparable to R502
• Non-flammable
• Compressors must be
• charged with polyol ester oils 

 
Applications:
Cold Storage Cells
Supermarket Display Cases
Ice Machines
Replacement for R502
in Transport Refrigeration
Retrofit of existing R502 installations
with R404A is possible
