R22 (Chlorodifluoromethane)

R-22 (Freon 22, R22) is a colorless gas with weak specific odor. It is used for obtaining temperature up to minus 40°С at first stage and temperature up to minus 60°С at second stage in refrigerating units and in household and industrial air-conditioners. It is also used as a mixture component, a pore-forming agent for producing plastic foam and for obtaining fluoro-monomers and other fluoro-organic substances. R-22 (Freon 22, R22) is a non-combustible and non-explosive gas. Self-ignition temperature is above 700°C. In case of contact with flame or hot surfaces, it decomposes producing highly toxic products. It reacts with chlorine and bromine at temperature of 400-600°C in the gas phase or at catalyst. It is allow for production and usage until 2030. R-22 has been the dominant refrigerant in residential and commercial air conditioning and large chillers for air conditioning and industrial process cooling and for medium and low-temperature commercial refrigeration applications. It can also be used as an aerosol propellant for pesticide and paint, or as a fire extinguishing agent. It is a primary feedstock for fluoropolymers. R-22 has been subject to reduced production and restriction in new equipment since 2010, and production of the refrigerant is to end in 2020. The use of R-22 is allowed until the supply has been depleted. R-22 is non toxic and non flammable meeting the highest A1 Classification.

Product Features and Benefits

Whilst an excellent product across its traditional usage areas, R22 is an ozone depleting product and as such is subject to being phased down. It will still be available in Vietnam until 2030 and can be obtained as a recycled product from PVCK (to AHRI 700 standard). You should consult with your PVCK contact to learn more about suitable R22 substitutes for your application.

PVCK product cylinders are fitted with a Residual Pressure Device (RPD) to ensure used refrigerant or any other substance cannot be reintroduced into a cylinder

Store cylinders in a cool, dry, well ventilated area, out of direct sunlight

PVCK operates a returnable cylinder fleet, empty cylinders are to be returned to an A‑Gas wholesale partner.

For optimal performance and compatibility, PVCK recommends the use of valve fittings that have plastic sealing washers (e.g. Nylon, PTFE or PCTFE) for refrigerant products. Hard or inflexible materials such as fiber washers may cause minor connection leaks. The sealing washer should be visually inspected for damage or wear before each use. Fittings should be installed slightly tighter than hand-tight.
