  • Product Description

    Lab and industrial equipment low temperature refrigerated chilling ethanol chiller also know as low temperature cooling water / liquid circulation pump, recirculating chillers, refrigerated circulator, circulation chiller, water chiller or recirculating chiller, This device adopt mechanical refrigeration, the main function is provide low temperature liquid for other device to achieve low temperature condition, usually are used wherever heat needs to be dissipated reliably and fast, e. g. in laboratories for rotary evaporators, distillation systems ,condenser, jacketed glass reactor or analytical devices.   

    Product Advantages & Features

    1. Circulating refrigerant: Synthetic heat transfer oil, industrial alcohol or water-glycol mixture for circulating refrigeration, saving resources; strict circulation pipeline design to prevent circulating water pollution and prolong the use of circulating water; 

    2. Multiple security protections for more reliable operation; 

    3. Original imported compressor, stacked supercooled refrigeration technology; 

    4. Using subcooling technology to ensure the stability of temperature at low temperatures; 

    5. The temperature difference between turning on the compressor and turning off the compressor can be set; 

    6. Ambient temperature monitoring function to prevent the system operating environment temperature from being too high; 

    7. Multiple fault alarms (over temperature alarm, sensor alarm, high pressure alarm, compressor overheat alarm, liquid level alarm);

    8. It adopts full-closed design, no water absorption during low-temperature operation, ensuring the purity of cold and heat-conducting medium, preventing ice crystals and prolonging the service life of refrigerant; 

    9. High-performance circulating pump that guarantees continuous operation for 24 hours a day; 

    10. High efficiency plate type cold heat exchanger for heat exchange efficiency;


    Product Applications

    Applied in the fileds which need maintain under low temperature conditions of heavy , energy , food , pharmaceutical , biological engineering , metallurgy and other industrial production process .
