-25°C Closed Recirculating Chiller, Water Cooling Circulator
-25°C Closed Recirculating Chiller, Water Cooling Circulator
Closed Recirculating Chiller
Features
- 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,temperature range is -25°C~ 30°C,PT100 temperature sensor.
- Use of cold technology, can guarantee the stability of temperature at low temperature.
- Can set the temperature difference of compressor on/off.
- Monitoring the ambient temperature, prevent temperature to be higher in the running system.
- 10.A variety of fault alarm (over temperature alarm, sensor alarm, high pressure alarm, compressor overheat 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.
