GM Cryocoolers

Efficient Cooling For Custom Applications

A Gifford McMahon cryocooler with a cold stage, displacer tube, black anodised motor housing, and helium gas fittings.

Featuring single-stage and two-stage cryocoolers paired with our custom-designed K450 helium compressor, these coldheads provide rapid cool-down, adjustable speed, and a compact footprint.

Ideal for integration into various applications, including high-temperature superconducting (HTS) magnets, custom cryostats, low-noise amplifiers (LNA) for radio astronomy, and more.
