GM cryocoolers

Compact and economical Gifford McMahon coolers

The Coolstar range comprises some of the most versatile and cost-effective Cryocoolers available today. With applications as diverse as radioastronomy and shield cooling for magnets, the Coolstar range of Cryocoolers offers fast cooling speeds, long service intervals and easy OEM integration.

Oxford Cryosystems took over the range (previously manufactured by Edwards High Vacuum) in 2008,  and we now design, manufacture and service Coolstar Coldheads and Cryodrive helium compressors in our Oxford (UK) facility.

The Coolstar range is ideal for  a range of different applications, which may include cooling for High-Temperature Superconducting (HTS) magnets, custom cryostat design and Low-Noise Amplifiers (LNA) for radioastronomy. We are particularly proud that we are currently involved at the design stage of the Square Kilometre Array (SKA), an international US$1.9 billion project to build the world’s largest radio telescope. Over the next 10 years, thousands of antennae will be built in South Africa with, potentially, up to 6 of our cryocoolers on each dish.

We are always excited to hear from potential users of our GM Coolers. If you have cooling requirements, whatever the application, why not contact us to discuss whether one of our GM coolers will be suitable?
