About this refrigerant
R134a (1,1,1,2-tetrafluoroethane / CH₂FCF₃) is a chlorine-free pure HFC refrigerant with an ODP of zero. For many years it has been used in numerous vehicle air-conditioning systems, medium-temperature commercial refrigeration and certain chiller systems.
Its ASHRAE safety class is A1. Depending on system design it is most often used with POE oils. R134a has a high GWP, so during service the refrigerant must not be vented to atmosphere and should be recovered with suitable equipment. Some newer applications are moving to lower-GWP alternatives.
Applications
Automotive air conditioning
Long-standing mobile AC refrigerant for passenger and light commercial vehicles designed for R134a circuits.
Commercial & retail refrigeration
Medium-temperature cabinets, cold rooms and food-service equipment where stable A1 performance is required.
Chillers & heat pumps
Positive-pressure centrifugal and other chillers, plus selected heat-pump systems designed by the manufacturer for R134a.
Appliances and transport refrigeration
Domestic refrigerators/freezers and transport refrigeration units designed around R134a properties.

Frequently asked questions
The ACC Refrigerant range includes R134a, R404A, R410A, R32 and R407C. If you are not sure which gas is right for your system, we recommend checking the equipment nameplate or the refrigerant code specified by the manufacturer. Share the information you have with us and we can help you find the right product group.
R134a is a pure HFC refrigerant used in many vehicle air-conditioning systems, medium-temperature commercial refrigeration and some chiller systems. Not every unit runs on R134a; product selection must follow the gas code specified by the equipment manufacturer. Contact us if you need stock or packaging information for R134a.
In general, no. The fact that two gases are used in similar applications does not mean they can be swapped directly. Operating pressure, compressor oil, safety class and system components can differ. Selection must follow the refrigerant code specified by the equipment manufacturer, and different gases must not be mixed in the same circuit. If you are considering a refrigerant change, we recommend obtaining approval from the manufacturer or an authorised technical service first.
