R22 Ametron Refrigerants is an HCFC refrigerant that operates with high pressure but low compressor displacement. Ametron Refrigerants® R22 is popular in residential, commercial and industrial applications. Ametron Refrigerants® R22 is also used as an intermediate to produce floropolymers and as a blowing agent in rigid foam applications.
In line with international agreements on the management of ozone-depleting chemicals, use of Ametron Refrigerants® R22 is progressively being phased out across the world. By 2010 most countries will no longer allow the production of Ametron Refrigerants® R22 for use in new air-conditioners. Moreover, the availability of the refrigerant to service those systems still using it will reduce and cease to exist as stocks are depleted.
Ametron Refrigerants
R410A will take the place of Ametron Refrigerants® R22 in most new air conditioners and to a lesser extent Ametron Refrigerants® 407C will also be used in some systems.
