Ultra-high Temperature Cooling Technology Can Directly Cool Down From 300℃ High Temperature. Because only the heat transfer medium in the expansion chamber is in contact with the oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the heat transfer medium. The risk of oxidizing and absorbing moisture from the air. No high-temperature heat medium evaporates at high temperature, and continuous control can be achieved with -80℃ to 190℃, -70℃ to 220℃, -88℃ to 170℃, -55℃ to 250℃, and -30℃ to 300℃ without pressurization temperature.

principle

Adopting a fully enclosed pipeline design and an efficient plate heat exchanger, it reduces the demand for heat transfer fluid while improving the system’s heat utilization efficiency, achieving rapid temperature rise and fall.

Because only the thermal conductive medium inside the expansion chamber comes into contact with oxygen in the air, it can reduce the risk of oxidation and absorption of moisture in the air. At high temperatures, no thermal conductive medium evaporates, and there is no need to replace the thermal conductive medium. Moreover, continuous temperature control in multiple temperature ranges can be achieved without the need for pressure.
