Working Principle

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.

Application: Various Reactors (Microchannels, Glass, Jacketed Reactors, etc.), Distillation or Extraction System, Laboratory, University, Research Institute, Aerospace, Automotive Industry, Semiconductor and Electrical Test, Chemical, Pharmaceutical, Petrochemical, Biochemical, Medical, Hospital, R&D Workshop, Aerospace, Biological and Other Industries.
