RIGID: Your Premier R134a Mini Compressor Supplier
RIGID R134a mini compressors are ultra-compact and achieve outstanding power density. Available in 12V, 24V, and 48V voltage input options and compatible with various currents.
The high-quality R134a DC Compressor is developed for small liquid cooling and dc air conditioning. It has features of the lightest weight, smallest size, and extraordinary efficiency to satisfy the growing HVAC market nowadays.
For smooth and easy temperature regulation, RIGID R134a mini compressors with cooling capacities from 100W to 1,000W (3,410Btu) are driven by our patented driver board. This drive board can be continuously controlled by the frequency of a square wave signal with speeds ranging from 2,000 rpm to 6,500 rpm.
RIGID R134a mini compressor is able to run on DC or AC power through an AC-DC conversion. An advanced motor drive controller provides a variable speed and load-following capability for precise temperature control and high efficiency. The R134a mini compressor is starting a new trend in various compact mobile cooling systems as well as small-footprint countertop appliances.
Today, RIGID mini compressor is ideally suited for compact refrigeration applications and cooling electronics. It is designed for small and mobile refrigeration, air conditioning, and heat pumps, as well as other numerous commercial appliance types, where space and weight are important.
