• ROTARY MINI DC COMPRESSOR

    -- Meet the Future of Smart Compact Refrigeration

    RIGID's miniature rotary DC compressors represent a significant advancement in vapor compression technology, delivering exceptionally low vibration and quiet operation. As the first true innovation in compact compressor technology in nearly a century, these compressors are engineered for high-performance thermal management across a wide range of applications, including compact recirculating chillers, portable refrigeration systems, medical cooling equipment, electronic cooling, and mini chilled-water systems.

    RIGID’s DC compressors offer cooling capacities ranging from 100W to 800W (up to 2,800 BTU), powered by our proprietary variable-speed drive board. This patented controller allows precise speed regulation via a square wave signal, with operating speeds adjustable from 2,000 to 6,500 RPM.

    As the core component of refrigeration systems, compressors function as the "heart" of the system - analogous to the engine in a vehicle or the heart in a living organism.

    RIGID Technologies now offers one of the industry’s most compact, lightweight, and efficient rotary DC compressors, designed specifically for mobile and space-constrained cooling applications. The latest fifth-generation model integrates a patented sine wave driver board for superior performance and energy efficiency.

    To sustain our position at the forefront of innovation, RIGID allocates a substantial portion of its annual revenue to research and development, ensuring continuous technological advancement and product excellence. PDF Download

    Thermal Management

    RIGID’s Miniature Rotary DC Refrigeration Compressors represent a new benchmark in compact cooling technology, offering high-performance, energy-efficient solutions tailored for space-constrained and mobile applications. Engineered for versatility and reliability, these compressors are redefining the possibilities in thermal management across various industries.

    Ultra-Compact Yet Powerful
    As small as a soda can and weighing just 720 grams, RIGID’s variable-capacity DC compressor delivers remarkable cooling power—achieving 450W to 800W in a single-cylinder configuration under standard ASHRAE conditions. Despite its miniature size, it offers the cooling capacity and performance of much larger systems.

    Wide Voltage Compatibility
    Designed to operate on 12V, 24V, or 48V DC, the compressor is also adaptable to AC systems via an AC-DC converter, making it highly versatile for both off-grid and stationary use. Compatible with R134A and R290A refrigerants, it meets global environmental and performance standards.

    Outstanding Energy Efficiency & Noise Reduction
    With its advanced BLDC technology and patented drive board, RIGID’s compressor provides up to 40% energy savings compared to conventional fixed-speed compressors. Its quiet operation - averaging just 48 dB(A) - makes it ideal for noise-sensitive environments such as medical devices, lab equipment, and portable systems.
