    Mini Water Chiller Cooling System-12V/24V/48V

    RIGID stands as a pioneering force in miniature compressor innovation based in China. Our ingenuity drives the advancement of compact cooling systems through cutting-edge technologies.


    The mini water chiller comprises four integral components: a mini compressor, micro-channel condenser, evaporator, and capillary or expansion valve. Within this water chiller configuration, the frame & plate evaporator functions as a condensed refrigerant-to-coolant heat exchange module.


    R134A refrigerant adeptly absorbs fluid-generated heat, facilitated by a circulating pump directing liquid flow through the evaporator and accompanying tubing.


    The small water chiller delivers remarkable advantages, including an exceptionally compact radiator and heightened heat dissipation capability. Its design emphasizes minimal size, leveraging a mini compressor to achieve unparalleled lightweight attributes. This Plate-type water chiller excels in precise heat transfer, proving invaluable in scenarios where spatial constraints and weight considerations are pivotal.


    RIGID has engineered robust liquid chiller solutions that merge compactness, affordability, and seamless integration into user systems. Our complete product range is not exhaustively featured here.
