Cryogenerators

Stirling Cryogenerators are based on the reversed-Stirling cycle. These Cryogenerators, also known as Cryocoolers or Cryo-refrigerators, are named SPC’s (Stirling Process Coolers) and are the heart and key component in all that Stirling does.

For more than 65 years, Stirling Cryogenics has been designing and supplying these high efficient, low temperature coolers. Over these years more than 6,000 machines have been supplied world-wide, in a wide range of demanding circumstances and different applications.

Stirling Cryogenerators provide cooling power in the range of 50 to 6,000 Watt in the temperature range of 18 to 180 Kelvin (-258 to -123°C or -433 to -190°F). Depending on the temperature and cooling power requirements, Stirling Cryogenerators are available in either a 1 or 4-cylinder version and in a one-stage (down to 40K) or two-stage configuration (down to 18K). Stirling Cryogenerators can be integrated into any kind of (customer) cryogenic system, be used as liquefiers for Nitrogen, Oxygen, Methane, Argon, Neon, etc., or as cooler for a Helium or Hydrogen gas flow or cryogenic liquid flow.

Stirling Cryogenerators can be installed to function in parallel to reach a higher capacities. Stirling has an in-house engineering department to design specific configurations to customise its cryogenic system so that it can be used in many different applications.

Unique features Cryocoolers

Stirling Cryogenerators have a number of unique features:

• Highest efficiency possible (through reversed Stirling Cycle technology) leading to low electricity consumption
• Fully automated and PLC controlled
• Process specific heat exchanger integrated in the cold head
• Flexible process integration
• Robust design with proven reliability: some Cryogenerators are over 40 years in operation
• All rotational and reciprocating seals work at ambient temperatures
• Maintenance friendly
• Annual inspection and cleaning can be done by customer’s engineer at site
• Worldwide service available; mostly with nearby local service engineer
• Various options available such as capacity control, ATEX, maritime version etc.
• Supply according to all applicable coding, power grid and requirements of the customers’ site.
