R410A is an R32/R125 blend used in split air conditioners, VRF/VRV and many heat-pump systems.
About this refrigerant
R410A is a near-azeotropic equal-ratio blend of R32 and R125. It operates at higher pressures than R22, so it must be used only with equipment and service tools designed for R410A. It has been widely preferred for many years in split AC, VRF/VRV and heat-pump applications.
ASHRAE safety class is A1 and ODP is zero. Typical applications use POE oil. Because of its high GWP, use of R32 and other lower-GWP alternatives is increasing in new equipment; service demand on existing R410A systems continues.
Applications
Split air conditioning
Wall, ducted and cassette splits designed for R410A operating pressures.
VRF / VRV systems
Variable-refrigerant-flow multi-split systems that use R410A.
Heat pumps
Air-to-air and light commercial heat pumps designed around R410A.

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.
R410A is an R32/R125 blend that has been widely used for many years in split AC, VRF/VRV and heat-pump systems. Operating pressures on R410A systems can differ, so service equipment must also be rated for this gas. If you are not sure which refrigerant your unit uses, you can share the nameplate information with us.
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.
