Scientific and technical entities dedicated to the development, production and trade of refrigeration equipment, ultra-low temperature freezers, refrigeration heating control systems, heating circulation systems, explosion-proof electrical equipment, automated integrated decentralized control systems, experimental equipment, and industrial freezers. Has a number of research and development team with rich experience in ultra-low temperature, high and low temperature development of high-quality professional designers. At present, the company is in the same industry advanced level in the research and development of single-machine refolding refrigeration technology, high and low temperature rapid rise and cooling technology research in the international advanced level. In particular, the precise temperature control of the reaction kettle is an internationally advanced single medium control-90 degrees to +250 degrees continuous temperature control, and the temperature of the reaction kettle material is precisely controlled linearly. The product temperature range ranges from -152 degrees to 350 degrees.
