• Mini Water Chiller

    A Reliable Supplier for Mini Water Chiller and Leading Mini Cooling Solution Manufacturer

    Different from traditional water chillers, RIGID mini water chillers adopt miniature brushless dc compressors. It enables our liquid chillers ultra-small and most lightweight. Our mini water chiller is a compressor refrigeration system designed to cool air and/or liquids. In order to do so, they utilize a refrigeration cycle that lets them remove heat from various liquids and release it into the atmosphere. In a chilling system, their use precedes directing the chilled liquid/coolant to a heat exchanger, process equipment, or other liquids.


    RIGID mini water chillers are also used to provide mixture liquids cooling on battery thermal management and provide temperature control for battery, medicines and lab chemicals.

    Our world's smallest size and lightest weight mini water chillers are essential to industries including medicine and esthetic & medical device, food and beverage, plastics manufacturing, HVAC, laser, chip and PC.


    RIGID supplies a series of custom refrigeration systems that provide various size thermal management solutions in ultra-compact.

    • 2.5 kgs/5.5lbs;
    • Water cooler with compressor
    • Size: 200x230x145 mm/7.8x9.0x5.7 inch;
    • 12V/24V/48V dc compressor to enable peak performance;
    • Portable mini chiller unit system provides reliable small refrigeration solution;
    • DC compressor cooler provides affordable cooling solution where size/space / efficiency are important factors.


    The benefits of mini water chillers include ultra-small size and high heat flux. Furthermore, an advanced motor drive controller provides a variable speed and load-following capability for precise temperature control and high efficiency.

    The major advantage of RIGID mini water chiller is, it comes with a sine wave drive board. The variable speed control board controls compressor speed. Users can adjust compressor speed to get the best performance they needed, as well as precise temperature.

    RIGID water chiller module is good for customers who's applications are Lithium battery cooling or electronics cooling or medical device cooling etc. They want a mini chiller system only to integrate or assemble with their machine or equipment, in order to get recirculating water-cooled to chill their equipment's heat part.

    RIGID mini water chiller offers 12V, 24V, and 48V voltage input options and is compatible with various currents. It is widely applied to battery, electronics, laser, medical devices and other thermal management of precise instruments. It provides excellent cooling performance.

    Apart from the standard mini chiller system, RIGID also custom made or personalize small cooling modules to meet customer's special demands.

    P-Plate Liquid Chiller

    Plate Type Water Chiller Cooling System-12V/24V/48V

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

    Plate water chiller system consists of 4 major components: a small compressor, a micro-channel condenser, an evaporator, and capillary or expansion valve.


    In a water chiller system, the frame & plate 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 Plate-P water chiller module include an ultra-small radiator and high heat flux. It has a very compact size in the design. By using a mini compressor, it has features of the lightest weight as well.


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


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