Temperature range is -25℃~+100℃, which can be extended to +135℃ according to the actual situation, and the temperature control accuracy is plus or minus 0.5℃. The  equipment can control the flow and pressure independently while controlling the temperature, and different customized solutions are required for simultaneous control.

  The tested object is attached to a test platform adapter.
The inside of the part was cooled and heated by an aqueous solution of ethylene glycol.
  The test component needs to go through a specific temperature profile and record changes in temperature.
  When performing a tolerance test, it usually takes an infinite loop.

  Equipped with a powerful circulation pump while ensuring the delivery of highly viscous liquids.
   Control the flow output with variable frequency regulation or proportional control valve to achieve high precision control total range 5%~100% adjustment.

Product Description

The System Process Flow Is As Follows:

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air in the interior of the tank. The temperature rises from liquid to gas, and is sucked into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas after compression by the compressor passes through The oil separator separates the refrigerating machine oil carried in the compression process, and then enters the condenser, and exchanges heat with ambient air or cooling water to change from high temperature and high pressure gas to high pressure normal temperature liquid. The high-pressure normal temperature refrigerant liquid is dried by a filter and then throttled and depressurized by an expansion valve, that is, from a high-pressure liquid to a low-pressure liquid. The low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling air is brought to the inside of the tank through the circulating air to achieve refrigeration.

The anti-freeze solution is injected into the 80L pressure vessel, and the fully closed circulation system is adopted. This avoids the opportunity for the antifreeze to contact with the outside air and ensures the condensation of the water. After the expansion tank is protected by nitrogen, the temperature range of the heat transfer liquid is also broadened because its boiling point is increased. In addition, oxidation of the thermally conductive liquid in contact with oxygen in the environment is also avoided, thereby extending the useful life of the thermally conductive liquid.
