Features:

  • Multi channel output, independent control of flow, no interference with each other.
  • Temperature, flow and pressure can be controlled separately.
  • Multi channel temperature control, and one device can achieve multi channel output, and control the flow separately.
  • Strong circulation pump ensures the delivery of high viscosity liquid, it can provide high flow under stable pressure.
  • Clear circuit, compact structure, multiple fault alarm functions to ensure safe operation of the equipment.
  • Temperature variation range is usually from -40 to 100 degrees (which can be extended to 150 degrees). While controlling the temperature, you can also choose to control the flow or pressure;
  • Equipped with powerful circulating pump to ensure the delivery of high viscosity liquid; Variable frequency regulation or proportional regulation valve is used to control the flow output to achieve high-precision control of 5% ~ 100% of the total range.
  • The temperature control equipment can be flexibly connected with other test platforms;

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.

Product features and advantages:

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.
