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

DC Compressors: Compact Powerhouses for Advanced
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.ONLINE STORE
