Unique Sauer Advantages

Gas-tight:

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 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.
