Features of Refrigerated Circulators

  • Saving resources. Closed cycle pipeline design highly prevent circulating water pollution and extend the lifetime of circulation liquid.
  • Multi-safety protection, more reliable operation.
  • Brand compressor, cascade refrigeration cooling technologies.
  • Human design, more convenient and flexible.
  • Efficient two-condensate system.
  • Computer-cascade temperature controller,temperature figures display, adjustable unit is 0.1°C, PT100 temperature sensor.
  • Can set the temperature difference of compressor on/off.
  • Monitoring the ambinet temperature, prevent temperature to be higher in the running system.
  • A variety of fault alarm (over-temperature alarm, sensor alarm, high pressure alarm, compressor over heat alarm,liquid level alarm).
  • Power on delay protection, three-level cascade system protectors.All parts are safety grounding.
  • Adopt full closed circulation design, no water vapor at low temperature and ensure the purity of cooling medium, in case of ice crystals, provide a long time life of heat transfer liquid.
  • High-performance circulating pump, can guarantee 24 hours continuously running a day.
  • Use plate cool-heat-exchanger, heat transfer efficiency is provided.

Advantages of Refrigerated Circulators

refrigeration principle

Refrigeration Principle

The whole working principle process of industrial water chiller can be roughly divided into three parts: water circulation system, refrigeration circulation system and main control system. The water circulation system is also a part that directly reflects the function of the industrial water chiller. It transmits the cold water to the equipment that needs to be cooled, and the cold water absorbs the heat of the equipment and then transmits it back.

The refrigeration cycle system is a process of cooling the cold water that absorbs heat. The refrigerant sublimates and then compresses to bring the heat in the cold water to the outside for dissipation. The main control system is the power control and internal structural components control.

Display Function

  1. Display all the kind of process control temperatures.
  2. Shows the liquid level of the heat conducting medium in the expansion vessel.
  3. Shows indication for refrigeration system working.
  4. Shows indication for circulation pump working.
  5. Display the temperature control.
  6. The temperature upper limit, lower limit control can be set.
  7. Shows the alarm to add the liquid when it is empty.
  8. The refrigeration compressor can be set to operate manually or automatically.

Custom Explosion Proof Cabinet

Positive pressure cabinet is composed of positive pressure cavity and control cavity.

Positive pressure cavity is used for installing various of instrument or electronics which with non-explosion-proof.

The control cavity has explosion-proof control box and pressure control system.

The case material of positive pressure cabinet with 2~3mm Cold rolled steel sheet welding and the Air-duct with galvanized steel pipe.

Adopt bulkhead connector and tightening device for in&out of the cable.

There is a glass display in the front of door and display the information of instrument and indicator light.
