Refrigerant Gases

Mihama Refrigerant Gases R-22


The efficiency and utility of Metron® 22 as a refrigerant and air conditioning fluid is reflected in its extended usage under the Montreal Protocol. Metron® 22 still plays a vital role in reducing Ozone Depleting Substances (ODS) levels in many markets.
