air cooled chiller
Description
♦ 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 colling technologies
♦ Human design,more convenient and flexible
♦ Efficient two-condensate system
♦ Computer-cascade temperature controller,temperature figures display,adjustable unit is 0.1℃,temperature range is -125℃~-20℃,PT100 temperature sensor.
♦ Use of cold technology,can guarantee the stability of temeprature 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.
♦ A variety of fault alarm (overtemperature 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.
