Gifford-McMahon Cryocoolers

20-30K Gifford-McMahon Cryocoolers

From hydrogen liquefaction to fusion research, our 20-30K cryocoolers are a versatile solution for both industrial use and research applications, providing extremely powerful cooling in the 20 K temperature range. They are widely used to cool high-temperature superconducting applications or hydrogen fuel cells used in zero emission aviation.

From this class, the AL630 Gifford-McMahon Cryocooler sets the benchmark, delivering 100 W of cooling capacity at 20 K — the most powerful GM cryocooler in our portfolio.

80K Gifford-McMahon Cryocoolers

Our 80K Gifford-McMahon cryocoolers are ideal for applications that require nitrogen or argon gas to be condensed into liquid form. Engineered for demanding environments, they maintain consistent, robust cooling even under high thermal loads, and are used across numerous research, medical, and industrial settings, from superconducting power delivery to neutrino detection scintillators.

The AL600 Gifford-McMahon Cryocooler offers the highest cooling performance of our 80 K cryocooler range, delivering 600 W of cooling capacity at 80 K.

Reliable Performance. Easy Maintenance.

Our Gifford-McMahon Cryocoolers have a mean time between maintenance of 10 000 hours, backed up by a 3-year or 8 000-hour warranty (whichever comes first). This extended service interval reduces operational interruptions and lowers lifecycle costs, making them ideal for dependable operation in continuous-use environments. And when maintenance is required, it can typically be carried out on location, resulting in less disruption to your work.

With thousands of installations across the globe, our GM cryocoolers provide the proven, trusted Cryomech performance that you can rely on for years.

Orientation Independent

Gifford-McMahon Cryocoolers can be installed in virtually any orientation—vertical, horizontal, or angled—without compromising their performance, making them ideal for setups where flexibility is essential.

The Original GM Cryocoolers

Cryomech’s founder William Gifford is the Gifford in Gifford-McMahon, and was part of the team that invented the technology over 60 years ago. Since William Gifford developed the first commercial GM Cryocooler in 1963, over 20 different baseline Cryomech models have been introduced. The vast experience in cryocooler design and manufacturing accumulated by the Cryomech product team continues to fuel cryocooler product development at Bluefors.
