    Guangxi Cooler provides customized services, you can choose different compressors to assemble the refrigeration cold storage condensing unit, please contact us for details
    The optional brands of compressors are as follows.



    Stable&Reliable; High efficiency&energy saving; Compact&nimble; Easy operation&convenizence

    1. The working status of multiple compressors is automatically controlled by pressure sensors to save operating costs and can be used in food, medicine, chemical, fruit storage and other industries.

    2. Through the combination of multiple compressors, a multi-stage output power combination can be obtained, which can be adjusted according to load changes to achieve the best energy, improve efficiency, and save energy.

    3. Since the screw compressor is a multi-machine, even if a single machine fails, it can be cooled by several other machines.

    4. A complete safety guarantee system such as high pressure, low pressure, oil pressure difference, overload, overheating, etc., can ensure the normal operation of high temperature or low temperature under severe conditions.5.Use r404a/r134a refrigerant.
