Isceon MO-49Plus (R-437A) header

Isceon MO-49Plus is an HFC refrigerant gas, suitable for the replacement of R-12 in air-conditioning applications for vehicles and small, medium temperature, refrigeration equipment (domestic refrigerators and freezers). It is also suitable for substituting HCFC mixes (like R-401A, R-401B, R-409A) in direct expansion, refrigeration systems. It is not suitable for installations with centrifugal compressors or flooding evaporators.

Systems for air conditioning of vehicles designed for R-12. Systems for refrigeration designed for R-12.


  • Allows easy, economical retrofit, replacing R-12, HCFC blends such as R-401A, R-401B, R-409°. It also substitutes Isceon MO-49 (R-413A)
  • In most cases it is not necessary to change the lubricating oil (compatible with new and traditional oils)
  • Allows the continued use of existing facilities
  • After the retrofit it is possible to top-up the circuit without needing to empty it.
  • The system cooling capacity is similar or slightly lower than that with R-12
  • The gas flow temperature is slightly lower than that with R-12.

Compatible lubricants:
Polyol ester oils (POE), also compatible with alchylbenzenes (AB) mineral oils (MO)

Classification ASHRAE for safety purposes: A1
