| Daikin Industries is the only manufacturer in the world to make it all from fluorocarbons to air-conditioning units. We will be constructively developing both refrigerants and hardware for full-fledged use of HFCs in the 21st century. |

Under the Montreal Protocol, CFCs were completely banned as of the end of 1995 and the overall use of HCFCs was regulated as of 1996 in order to reduce any harmful effects on the ozone layer. Events like these have sparked development of alternative refrigerants the world over in preparation for a complete ban on all harmful fluorocarbons.
Daikin Industries is the only manufacturer in the world to make it all from fluorocarbons to air-conditioning units. We are focusing development on HFC mixed refrigerants as alternatives to HCFC-22 and R-502 widely used in the refrigeration and air-conditioning fields. HFC mixed refrigerants save energy and do not destroy the ozone layer. In anticipation of the full-fledged use of HFCs in the 21st century, we are building production systems to produce HFC-134a, 32 and other types of HFC refrigerants. |
