    Coaxial Liquid Chiller

    • 5 kgs/11lbs;
    • Size: 330x200x150mm;
    • Micro cooling refrigration system;
    • 12V/24V/48V mini compressor to enable peak performance;
    • Rotary refrigeration compressor provides reliable small refrigeration solution;
    • DC compressor cooler provides affordable cooling solution where size/space/efficiency are important factors.


    The Coaxial-C liquid chiller module is a circulatory cooling subsystem. It consists of micro dc 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 smallest compressor cooling unit is developed aim to satisfy the growing market who wants small liquid refrigeration cycle systems.


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


    The benefits of Coaxial-C liquid chiller module include very compact radiator and high heat flux, it provides excellent cooling performance.


    RIGID liquid chiller module is good for customers who is able to deal with system control. We provide drive board together accordingly.


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


    End user’s control board can connect with RIGID 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.

    Coaxial Liquid Chiller Refrigeration System-12V/24V/48V

    RIGID is a miniature compressor innovation leader in China. We are creative and capture new technologies in compact cooling systems.

    The coaxial liquid cooler system consists of 4 main components: a dc compressor, a micro-channel condenser, an evaporator & a capillary or expansion valve.


    In a coaxial liquid chiller system, the stainless steel evaporator is typically a compact refrigerant-to-coolant heat exchanger.


    R134A refrigerant absorbs heat from the fluid. A pump is used to circulate liquid through the evaporator and tubing or piping.


    The benefits of RIGID Coaxial-C liquid chiller module include an ultra-small radiator and a coaxial stainless steel evaporator. It has a very compact size in the design. By using a mini compressor, it has features of lightest weight while excellent heat transfer performance as well.


    The coaxial type liquid chiller also provides focused heat transfer and is especially useful for applications where space and weight are critical matters.


    RIGID has developed robust liquid chillers which are compact, use low-cost parts, and frequently integrate directly into the user’s system.
