    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 1780W 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, R290A, R600A and R1234Y Frefrigerants, 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.
