    E-Copper Coil Liquid Chiller

    • 3 kgs/6.6lbs
    • Size: 275x175x138mm
    • Compact & small liquid chiller;
    • 12V/24V/48V compressor to enable peak performance;
    • Closed loop liquid chilled system provides reliable cooling solution;
    • Efficient DC compressor provides cost-effective cooling solution where size/space/efficiency are important factors.


    The Copper Coil-E liquid chiller module is a circulatory cooling subsystem. It consists of mini compressor (12V/24V/48V) with R134A coolant, smallest condenser and radiator, copper coil evaporator (heat exchanger), filter drier, driver board and other refrigeration parts.


    The small cooling unit is developed aim to satisfy the growing market who wants microclimate cooling systems.


    The copper coil-E liquid chiller module is a kind of heat transfer system, sophisticated design by our skilled engineers.


    The copper coil chiller unit is not only facilitated installation but also assures end users having the latest micro cooling solutions.


    RIGID liquid chiller module is good for customers who is able to deal with system control.


    They want cooling subsystem module only to integrate or assemble with their machine or equipment, in order to get small cooling solution.


    User’s control board can connect with our DC compressor drive board (included) to control compressor speed and get the best performance they needed.


    Except standard chiller unit, RIGID also custom made or personalize small cooling modules to meet customer's special demand.
