Precautions

Safety Notice

R22 is an HCFC controlled substance under the Montreal Protocol and its production is being phased down. It remains suitable for servicing existing equipment; new systems should consider low-GWP alternatives such as R32, R290 or HFOs.

Storage & TransportStore in a cool, well-ventilated warehouse away from fire and heat sources; temperature not above 52℃. Keep separated from oxidizers and acids. Cylinders must be periodically inspected; handle gently to avoid damage.

Frequently Asked Questions

Which refrigerants can replace R22?
Common replacements for R22: R32, R410A, R407C, R454B or hydrocarbon R290. Suitability depends on system design and operating conditions — our technical team can confirm the right choice for your equipment.
What are the GWP and ODP values of R22? Is it regulated?
R22 has a GWP of 1810 and an ODP of 0.055 (ASHRAE safety class A1 (Non-toxic, Non-flammable)). HCFC refrigerants are in the phase-out stage, with production and use under quota licensing.
Is R22 safe? What is its safety classification?
