The Coolstar range comprises some of the most versatile and cost-effective Gifford McMahon (GM) Cryocoolers available today, offering fast cooling, long service intervals and easy OEM integration.
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.
The Coolstar single stage coldheads comprise the 0/12 and 0/40 models, respectively delivery cooling powers of 12 and 40 W at 77 K.
The Coolstar two stage coldheads comprise the 2/9 and 6/30 models, both delivering base temperatures as low as 10 K.
The K450 compressor delivers compressed helium to the Coolstar coldhead and controls coldhead motor speed for optimised performance.
