Compact, variable-speed GM coolers
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.
The Coolstar single stage coldheads range includes the 0/12 and 0/40 models, respectively delivery cooling powers of 12 and 40 W at 77 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
The Coolstar range is ideal for use wherever a compact and variable speed head is desirable and in applications from laboratory cryostats to radio astronomy. The main features of the single stage coldheads range includes:
- 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 77 K in as little as 11 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
