Flexible line with thermal performance of standard rigid line? Yes it is possible!

A 60m single stretch length has been tested and approved by CERN!

During the rigorous testing it has been proven that the Cryoworld flexible line has the best performance on the following specifications:

  • Thermal; less than 1W/m for a DN100 inner bore line, a (cryo)world record!
  • Smallest outer diameter; only 175mm for a DN100 line
  • Highest flexibility; flexible instead of semi-flexible
  • Very rugged outside protection, full stainless steel, fire safe


It is also possible to have the flexible in a coaxial design, cooled by return gas, resulting in extremely low heatloads on the inner flow. Subsequentely this results in extremely long possible cable lenghts.
