DW-YQ-5/10 DW-YQ-5/20 Low Temperature Cooling Circulator

The DW-YQ Series low-temperature cooling circulator uses mechanical refrigeration to provide stable circulating coolant or a low-temperature bath for laboratory and process applications. It can be connected to rotary evaporators, freeze dryers, vacuum systems, electron microscopes and other temperature-sensitive equipment, providing continuous cooling for chemical, biological, physical and materials research workflows.

  • -20°C Minimum No-Load Temperature
  • ±0.5°C Temperature Control Accuracy
  • 18 / 25 L/min Maximum Circulation Flow
  • 7 m Pump Lift
  • 2 / 5 L Tank Volume

Features of DW-YQ Series

  • Imported totally closed compressor group and water circulation pump in international famous brand, which has advanced property and reliable performance.
  • The key componnets of refrigerating unit, like relays, protectors, capacitors and refrigeration parts are all quality components imported.
  • Digital display temperature with microcomputer temperature control, which is easy to operate and eyecatching.
  • The circulation system is made of anti-corrosion material, which is rust-proof, anti-corrosion and pollution free against low temperature liquid.
  • Engergy saving: DW-YQ series cooling circulator can prevent foulding and pullution in water shortage, poor water quality and poor water pressure circumstances, so that the big precision equipment can be protected in good operation under high temperature or other poor working environment.
  • All models can be customized with different lowest temperature, refrigerating capacity and water tank volume.
