At present, our company is the Council Member of China Solar Energy Thermal Utilization Industry Alliance and China Solar Energy Thermal Utilization Industry Association, the Council Member of China Heat Pump Industry Alliance, a member unit of Solar Energy and Auxiliary Energy complementary Heating/Refrigeration Engineering Professional Committee.

Focusing on green technology and relying on the supports of Applied Chemistry Institute of Shandong University, we are specializing in the research and development of environment-friendly chemical products, and maintain strategic cooperative relations with many universities and a number of well-known chemical companies in the world. With "Zaineng" and "Zeneng" as two major brands, we now produce four series of products: Solar thermal conducting medium, Heat pump energy exchange fluid, Adblue and Polyurethane release agent. We are working hard to provide excellent services for environmental protection and energy-saving-emission-reduction industry, and offer healthy "blood" and "purification solution" to defend blue sky and fight haze.

Our company takes "normativate market and ensure product quality" as mission, and actively participates in the establishment of relevant standards; sponsored by Shandong Province Environmental Protection Bureau and proposed by Shandong Province Quality and Technology Supervision Bureau Standard Technology Committee, our company compiled "Technical requirements for environmentally friendly products, solar water heating system-Heat conduction medium Glycerin, propylene glycol" (DB37/T2953-2017) the first draft; this standard was published by Shandong Province Quality and Technology Supervision Bureau on April 14, 2017 and began to use since May 14, 2017; it is the first local standard of China for this type of products. our company compiled "Technical specification for low temperature air source Heat pump (air conditioning) system" (DB37/T5095-2017), was approved and issued by Shandong Province Housing and Urban-rural Construction Bureau and Shandong Province Quality and Technology Supervision Bureau on April 26, 2017; it began to use since July 1, 2017. This standard is defined clearly in the relevant anti-freeze measures: "in accordance with the characteristics of the system and the pipes, the anti-freeze solution specially prepared for environmental friendliness, low toxicity, safety, anti-corrosion and low viscosity should be added exclusively". At the same time, our company is also the main drafting unit of the industry standard of "solar low temperature heat utilization medium" prepared by the national energy administration.

Sticking to such principle of "being perfect, unity and cooperation, user first, honest business" and policy of "getting survival by excellent quality and further development by excellent credibility", we are dedicated to offering customers excellent services. We look forward to working with domestic and foreign customers to establish a wide range of friendly relations of cooperation, warmly welcome all your inquiries and businesses.
