Shandong Dongyue Refrigerants Co. , Ltd was founded in 1987 and has become the Leading in scale environment-friendlyrefrigerant basement in the world. Its main refrigerant products include R22, R32, R125, R134a, R152a, R142b and Dongyuemixed refrigerants etc, with overall capacity of more than 500,000 tons. Shandong Dongyue Refrigerants Co. , Ltd, one of thedominant industries in Dongyue Group, has taken development and industrialization of environment friendly refrigerants as its strategic development focus over the years and successfully developed a series of Dongyue-Tsinghua Green Refrigerants cooperated with Tsinghua University in 1998. Those products won the "National Technological Invention Award". In recent years, Dongyue has developed refrigerant technology and independently developed another series of energy-saving and environment-friendly refrigerants. Those products has gained the ASHRAE refrigerant numbers and recognized by national authorised council that they are accord with state industry policies and some performance parameters are superior to those of the similar foreign products, with the total technical level has reached the international advanced one, and with superior thermal performance, non-toxicity and non-flammability, direct flling, low transfer cost and good economic and social benefts.Dongyue now has over 30 kinds of alternative refrigerants, has applied for over 90 national invention patents, among which over 50 patents are authorized .

Innovation is the motive power source of development of Shandong Dongyue Refrigerants Co., Ltd. The company attaches importance to the research and development of new products, actively carries out the research on the fourth generation refrigerants, including HFO-1234yf, HFO-1234ze, HCFO-1233zd and HFO-1336mzz etc, while grasping the key technology of the fourth generation refrigerant. Responding to the international/national policy requirements, the company actively pushes forward the elimination of the second generation refrigerants HCFCs substances and the reduction of the third generation of refrigerants HFCs substances, making full efforts and preparation for goal of the carbon peaking and carbon neutrality. The company has massive technological reserves in the area of fluorinated electronic special gases. It has self-developed electronic grade R23, electronic grade R32, electronic grade C318, electronic grade R218, electronic grade R125,electronic grade R116, electronic grade R41, medical grade R134a, medical grade R152a etc, and reserved key producing technologies of electronic grade tungsten hexafluoride, electronic grade nitrogen trifluoride, electronic grade hexachlorobutadiene.
