Coolstar Two Stage Coldheads - delivering base temperatures as low as 10 K
Our Coolstar range 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.
Available in either 2/9 and 6/30 models, both deliver base temperatures as low as 10 K. These are some of the smallest GM coldheads available, and can be installed in systems where space is at a premium.
Features & Tech Specs
Our two stage coldheads are ideal for use wherever you need a compact and variable speed head and in applications from laboratory cryostats to radio astronomy. The main features include:
- 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 integration into OEM systems.
- Fast cooldown time: Increased Coldhead speed makes it possible to reach 20 K in as little as 16 minutes.
The only commercially available range of GM cryocoolers
Our Coolstar systems give you complete control of the coldhead speed. By using a variable speed stepper motor, combined with proprietary control software, every Cryocooler in the range can be operated at speeds from 40- 90 rpm. This offers major advantages to the user 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 increased control for integration into cryostats or custom designs.
Fast cooldown time
Increased coldhead speed makes it possible to reach 20 K in as little as 16 minutes (depending on Coldhead).
The compact size, range of cooling power and orientation independence of the Coolstar range lends itself to a wide
range of applications including:
- shield coolers
- laboratory cryostats
- radio astronomy
- custom cryostat design
