Product Applications

Aspen variable speed refrigeration compressors are designed for connection to 12/24/48V DC power supplies and are compatible with various refrigerants including R134a, R124YF, R513A, R404a, 600a, 290a, and most of the upcoming low GWP refrigerants.

Our compressors are quiet and have low energy consumption. They operate in conditions where battery, vehicle, grid, or solar power is available as a direct current electrical source. Our compressors provide compact power, precision control, and unique flexibility, fulfilling a growing need for miniature thermal management systems.


The Aspen hermetic rotary compressor can be used in air conditioning units, water chillers, and commercial refrigeration systems. Because of their small size and light weight design, they can be applied in mobile or portable systems using either battery or vehicle power. This also makes them very suitable for small stationary applications, such as cooling electronic components and assemblies.

Our BLDC compressors can be configured with standard mechanical type thermostats as used in refrigeration appliances, or with electronic thermostats. These are just a few of the many potential applications for our unique compressors.
