Stirling Cryogenics, one of DH Industries trademark brands, developed the Stirling-cycle cryogenerator almost 60 years ago and it has been the cornerstone of our sophisticated cooling systems ever since. The Stirling cryogenerator makes it possible for our systems to produce temperatures ranging from -75 °C to -250 °C. More than 3.000 systems are in operation across the globe, often in extremely demanding conditions.
