The refrigerant gas R422D was designed to be the direct substitute of R22. It is a mixture of gases, which don’t damage the ozone layer. R422D can be used in refrigeration systems with medium temperatures at domestic and commercial air conditioners. In cases of leakage, the equipment can be recharged without any problem. It is compatible with the manufacturer’s original oil and the discharge temperatures are much lower, which contributes to prolonging the life of the compressor. Always load in liquid state/form.
