Product Name	ASHRAE #	Product Description
Genetron^® 407C	R-407C	A long-term, non-ozone depleting replacement for R-22 in various air-conditioning applications as well as in positive displacement refrigeration systems. For new equipment and retrofits. Not recommended for use in chillers with a flooded evaporator.
Genetron^® 422D	R-422D	A long-term non-ozone depleting replacement for HCFC in low- and medium-temperature commercial refrigeration systems and as retrofit solution in air conditioning installations. Suitable for direct expansion evaporators. Do not use in systems that employ flooded evaporators. For new equipment and retrofits.
Genetron^® 245fa	R-245fa	A non-ozone depleting candidate replacement for R-11 in centrifugal chillers. For new equipment.
Genetron^® 134a	R-134a	Replaces R-12 in auto air conditioning and in residential, commercial and industrial refrigeration systems. For new equipment.
Genetron^® 22	R-22	As a refrigerant, operates with higher system pressures but low compressor displacement. Popular in residential, commercial and industrial applications.
Genetron^® AZ-20^®	R-410A	Widely accepted to replace R-22 in air conditioning and refrigeration applications. For new equipment – not for retrofits.

Product Name	ASHRAE #	Product Description
Genetron^® 11	R-11	Low-pressure refrigerant for centrifugal chillers.
Genetron^® 12	R-12	A widely used refrigerant in reciprocating and rotary type equipment and in some centrifugal designs.
Genetron^® 113	R-113	Genetron^®113 offered low pressures and high gas volumes and was used in primarily in centrifugal chillers.
Genetron^® 114	R-114	Genetron^® 114 is intermediate in pressure and displacement. Principally used with chillers for higher capacities or for lower evaporator temperature process-type applications.
Genetron 123	R-123	A very low ozone depleting compound that serves as a replacement for R-11 in centrifugal chillers. For new equipment and retrofits.
Genetron^® 500	R-500	Genetron^® 500, an azeotropic mixture, has slightly higher vapor pressures and provides higher capacities from the same compressor displacement. A mixture of R-12 and R-152a, R-500 was mostly used in dehumidifiers.
