Refrigerant Color Codes
Color Codes
Refrigerant color codes are useful for us to recognise the type of gas that is stored in the cylinders. The name of the gas
are usually labelled on the cylinders as an added aid so that we will not make any mistakes in recognising them. Putting the
wrong gas into our air conditioning systems can damage the compressors.
Take note that in the future, all CFCs and HCFCs will eventually be phased out due to their effect on the ozone layers.
