Frequently Asked Questions
RIGID miniature DC compressors deliver powerful, quiet, and efficient cooling – enabling compact, lightweight refrigeration solutions for modern mobile and portable systems.
A RIGID DC compressor is a miniature rotary compressor designed for compact refrigeration systems. It operates on 12V, 24V, or 48V DC power, delivering high efficiency, low noise, and lightweight performance for portable and mobile cooling applications.
RIGID DC compressors are exceptionally compact, variable-speed, and optimized for battery, solar, and off-grid operation. Their miniature size and high COP make them ideal for mobile refrigeration, medical cooling, and electronics thermal management.
RIGID offers compressors in 12V, 24V, and 48V DC configurations, suitable for automotive, solar-powered, and industrial equipment.
RIGID compressors are compatible with R134a, R290, R1234YF, R513A, R404A, and R600a, supporting both traditional and eco-friendly low-GWP refrigerants.
They are widely used in medical devices, laser cooling, beverage dispensers, electric vehicle cooling, telecommunication cabinets, and portable refrigeration systems.
RIGID DC compressors achieve a COP up to 3.3, using advanced BLDC motors and inverter control to reduce power consumption while maintaining stable cooling.
Yes. Their DC power input allows seamless operation with solar panels and batteries, making them perfect for off-grid or renewable energy systems.
When RIGID miniature compressor is used in a refrigeration system together with a high-performance condenser and evaporator, the complete refrigeration system can be incorporated within a package as small as 100 in3 (1.64 liters). This allows a major space reallocation in the cabinet, namely much less volume for the refrigeration system and considerably more volume for product storage space. There’s also a weight reduction of approximately 10 lbs (4.54 kg) just from the use of mini-compressors. But for the most part, space savings are usually considered more important than weight savings in most refrigerated appliances.
A small vapor compression cooling system using RIGID miniature compressor would have even larger performance and efficiency advantages over thermoelectric coolers often used in various products in the absence of small compressors before. Above the cooling capacity range of 100W, the vapor compression-based system will be far superior to the thermoelectric systems: ¼ to ½ the weight and volume, and 1/3 to ½ the power consumption compared to thermoelectric systems.
