Sauer Helium Compressors have a leakage rate of < 0.001 psi

  • Gas-tight crank case with double lip seal at the crankshaft
  • Special helium suitable sealings and gaskets
  • Gas-tight hoses
  • Intake buffer tank and condensate collecting vessel
  • Gas-tight oil lock to the crank case
  • Vacuum flanges acc. to ISO 2861 at gas inlet
  • Encapsulated safety valves
  • Gas recirculation back to the suction side by a common piping

Reliability

Sauer Helium Compressors are designed for continuous operation.

  • Valves with modified stroke and spring suspension
  • Helium optimized lubrication
  • Efficient cooling, especially around the highly stressed valves

Test procedure

Sauer Helium Compressors are tested under operation conditions on a special helium test bench.

  • 16 hours running & performance test at final pressure with helium
  • Tightness check and measurement of the leakage rate with helium
  • 3.1 Inspection Certificate of Performance Data & Leakage Rate
  • Delivered filled with helium to avoid purge losses
