-- Miniature BLDC Rotary Refrigeration Compressors


    RIGID miniature rotary compressors are the result of a breakthrough in vapor compression technology featuring low vibration and low noise operation. Its tiny device is the first real innovation in micro-compressor technology for a century. They can be utilized in many thermal management applications from compact recirculating chillers, small coolers, medical cooling, electronic cooling, and mini-chilled water systems. RIGID mini compressors with cooling capacities range from 100W up to 800W (2,800Btu) by our patent drive board. The drive board is continuously speed-controllable via the frequency of a square wave signal, with variable speeds from 2,000rpm to 6,500rpm.


    Compressors are a key component of refrigeration products, it is the “heart” of such appliances, comparable to a car engine or even the human heart. RIGID Technologies now presents the lightest, ultra-compact, and more efficient Mini Rotary Compressor. The mini compressor is a new type of innovative micro dc compressor. Its compact and lightweight design makes it ideally suited for mobile and small cooling applications. Today, RIGID has successfully developed the 5th generation miniature compressor, which adopts our patented sine wave driver board.


    To maintain our technological edge, RIGID re-invests a large portion of corporate earnings back into R&D each year. PDF Download

    RIGID rotary refrigeration compressor is characterized by very small size and high performance. It is a variable capacity DC Compressor driven by a drive board. Its volume is very small like a coke can, and the weight is only 720g. The current models use a single-cylinder configuration under standard ASHRAE conditions, which can produce a cooling capacity of up to 450W to 800W.


    Compatible with R134A and R290A refrigerants, it can run at 12, 24, and 48V DC, and other voltages or AC power supply can be converted by AC and DC. RIGID's newly developed Miniature BLDC Rotary Refrigeration Compressors have begun a new trend, providing unparalleled cooling capabilities in various compact mobile cooling systems and other small footprint countertop appliances.


    Up to a 40% reduction in overall energy consumption and a 5 dB(A) average noise level reduction were measured by applying Variable Capacity Compressors as compared to conventional fixed-speed compressors.


    RIGID miniature compressors have the size, weight, and durability that make them well-suited to mobile or portable applications, including:

    • Small Cooling
    • Medical Device
    • Beverage Cooling
    • Small Refrigerators
