(Formerly known as 22a)
High Purity Alternative Refrigerant for R22, R404a, R407c etc.
Medium to low temperature Hydrocarbon Refrigerant
OZ-40 is a hydrocarbon based refrigerant blended from environmentally safe, naturally occurring hydrocarbons. This blend is a direct replacement or retrofit option used to replace HCFC and HFC refrigerants
such as R22, R404a, R407c.
OZ-40 has a number of applications and is most suited to medium to low temperature applications. The most common applications include domestic air conditioning, commercial air conditioning, commercial refrigeration,
wall splits, ducted systems, roof top packages, industrial cool rooms and freezers, agricultrual chillers and vats, dairy and wineries, supermarket cool units and displays.
OZ-40 operates at much lower head pressures and offers improved cooling properties and perfromance compared to R22 and R404a.
Why is the refrigerant purity such a major concern? Impurities such as other hydrocarbons can impact the vapour pressure of the refrigerant,
therefore lowering overall system efficiency. Sulphur can cause corrosion and unsaturated hydrocarbons can react with system components. Moisture in the refrigerant can lead to hydrolysis, corrosion and compressor failure.
Therefore it is critical to ensure that every system uses the correct and highest grade refrigerant available.
OZ-40 is compatible with most common refrigerant materials including R22 and R404a metal components, lubricants, seals, gaskets hoses compressors and o-rings.
Mineral oil is preferred, but also compatible with PAG, POE and AB lubricant oils.
Most common elastomer and plastic refrigeration materials used as o-rings, seals and gaskets are compatible with Oz-Chill Refrigerants.
Butyl hoses are incompatible and should not be used with hydrocarbon refrigerants.
