• 12V Mini Compressor

    The RIGID miniature refrigeration dc compressor is a breakthrough in vapor compression technology, featuring low vibration and low noise operation. Its tiny size is the first real innovation in miniature compressor technology in a century.
    RIGID mini dc compressors can be utilized in many thermal management applications, from compact refrigeration, small circulating coolers, tiny water coolers, medical cooling, direct cooling of electronics, micro dc air conditioners to mobile a/c cooling.
    RIGID micro and miniaturized compressors - Enabling the development of light, compact systems for refrigeration. Designed to optimize space and weight, mini compressors are perfect for small and mobile refrigeration. The small size of mini compressors makes them perfect for mobile or portable refrigeration, cooling electronics, and numerous commercial appliances where weight and space are important.
    For smooth and easy temperature regulation, RIGID miniature rotary DC compressors with cooling capacities from 100W to 1,000W (3,410Btu) are driven by our patented driver board. This drive board can be continuously controlled by the frequency of a square wave signal with speeds ranging from 2,000 rpm to 6,000 rpm.
    For over decades, RIGID rotary variable speed mini compressors have been an industry leader in DC Air Conditioner and Compact Commercial Refrigeration. With the most advanced technologies and high-quality standards, RIGID continues to exceed customer's expectations.
