Why are refrigerant cylinders color coded?

Refrigerant color codes are useful for us to recognize 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 recognizing them. Putting the wrong gas into our air conditioning systems can damage the compressors.

R-410A is a chlorine-free refrigerant that meets the U.S. EPA's newest, most stringent environmental guidelines. R-410A was developed as an alternative to R-22 (Freon), which will be phased out over the coming years in response to international environmental concerns.

Which is better R32 or R-410A?

In most cases R32 is the superior refrigerant when compared to R410A. While neither refrigerant depletes the ozone layer, R32 has a lower GWP and is easier to recycle. R32 also has lower operating and maintenance costs and is nowadays more common than R410A due to the phase out.

Is R32 replacing R-410A?

No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
