Our Compressors

Aspen Compressor models come in various sizes and specifications and can fit a whole range of applications: the A-Series, known for its compact size; the Q-Series, celebrated for quieter operation and higher cooling loads; the T-Series, equipped with a twin cylinder design for reduced vibration and increased cooling capacity; and the H-Series, tailored for height-restricted systems with horizontal operation. Our array of offerings ensures the right solution for every technical demand. View the full variety of compressor types here.

Aspen A-series Compressor

A-Series (Original)

These are the world's most compact single-cylinder rotary refrigeration compressors that Aspen pioneered. Originally developed by Aspen for US military applications in the early 1990's, these are the smallest and lightest compressors in the Aspen Compressor family. Available in 1.4 and 1.9cc displacements and 24VDC.

Aspen T28 Compressor

T-Series (Twin)

These 2-cylinder compressors are offered in 2.8 and 3.8cc displacements. The twin cylinder compressors offer double the cooling capacities of A or Q series, lower vibration and even quieter operation than their single counterparts due to the vibration cancelling twin cylinder design. They are available in both 24 and 48VDC. Aspen offers a DC-DC converter to operate the 48VDC version on 10 to 60VDC input power.

Aspen Q-Series Compressor

Q-Series (Quiet)

Offered in the same displacements as the A -Series, these models are equipped with more powerful motors to handle higher cooling loads as well as quieter operation than A-series. They are available in 12, 24 and 48VDC. 

Aspen Horizontal Compressor

H-Series (Horizontal)

The H-Series (horizontal) Compressors - These models are offered as twin-cylinder (2.8/3.8cc) as well as 4-cylinder (5.6/7.6cc) versions. Designed to mount and operate horizontally and specifically made for systems with 2-U (3.5 inches / 89 mm) height restrictions that cannot accommodate the T series. They are available in both 24 and 48VDC. Aspen offers a DC-DC converter to operate the 48VDC version on 10 to 60VDC input power.

Miniature Compressors:

Enabling Technology for Compact & Lightweight  Refrigeration Systems


Aspen mini compressors are exceptionally compact and achieve extraordinary power density. These small compressors are available in single cylinder, twin cylinder, vertical and horizontal configurations. Offered in 12V, 24V, and 48V voltage input options and compatible with various current and most of the upcoming low GWP refrigerants, these compressors can be used in a wide range of evaporator conditions and in LBP, MBP, and HBP systems. An advanced motor drive controller provides variable speed and load following capability for precise temperature control and high efficiency. 

Product Applications:

These high capacity vertical and horizontal mini dc refrigeration compressors are ideally suited for mobile or portable refrigeration, cooling electronics, and in numerous commercial appliance types, where space and weight are important.
