Two stage coldheads

The Coolstar two stage coldheads comprise the 2/9 and 6/30 models, both delivering base temperatures as low as 10 K. These powerful coolers are compact, lending themselves to a wide range of applications. The coldheads function independently of orientation.

Coolstar is the only commercially available range of Gifford-McMahon Cryocoolers offering complete control of the Coldhead speed; by using a variable speed stepper motor and proprietary control software, every cooler in the range can be operated at speeds of 40-90 rpm. This offers major advantages, including:

  •  Prolonged service intervals: Decreased Coldhead speed during low demand periods reduces wear on Coldhead seals.
  • Cooling power control: Varying the cycle rate second-by-second offers complete control for OEM integration
  • Fast cooldown time: Increased Coldhead speed makes it possible to reach 20 K in as little as 16 minutes

The Coolstar coldheads run in conjunction with the Oxford Cryosystems Cryodrive.

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?
