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 -80°C~-20°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 timelife 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.
