Refrigerant Gas

Product Description

Environmental-friendly refrigerants are representation of Dongyue new environmental protection strategy. At the beginning of 1990, in respect with the situation of caring for ozone layer protection all over the world, Dongyue cooperate with Tsing Hua University to develop new Environmental-friendly refrigerants in order to substitute for old refrigerants. Those new Environmental-friendly refrigerants are acknowledged and promoted by Environmental protection bureau of countries such as America and Europe, which also obtain its HS code. On 19th, Feb 2002, Our refrigents were awarded the honors of technical innovation in the science and technology conference of China State Department. Now we have owned 31 types of the new Environment-friendly refrigents. We are the largest supplier in the world. In addition we have constructed the globally largest CDM project in collaborating with Nippon Steel and Misubishi which has run since Mar 2007.
