Commercial Cryocoolers for use in HTS Applications

The emerging commercial HTS applications place expectations of high reliability, long service intervals, and environmentally robust cryocoolers. Whilst there have been several attempts at developing cryocoolers in the 300W to 2000W (at 77K) for these applications, the market need has yet to be satisfied. Fabrum Solutions in collaboration with Absolut Systems have formed a joint venture company, AFCryo, that produces a commercially available range of acoustic pulse tube cryocoolers featuring low maintenance, high power output, and cost effective operation. These cryocoolers utilize diaphragm pressure wave generators that hermetically seal the working fluids of the compressor from the helium working gas, ensuring zero degradation of the pulse tube performance. The efficiency, low servicing, and cost effectiveness of these cryocoolers suit the demands of HTS applications, in turn making the commercial success of HTS devices more achievable.
