Sauer Compressors Group

For more than 50 years Sauer Compressors specialises in the development and production of gas-tight helium compressors. Our comprehensive experience is incorporated in every product and new development – for the benefit of the customer.

Sauer helium compressors are specially designed for helium compression and represent the most efficient and safe solution for all kinds of applications. So it is no surprise that leading research institutes and universities only trust in Sauer helium compressors.

Gas companies profit from the unique advantages of Sauer helium compressors and the support of the worldwide sales and service network of the Sauer Compressors Group. 

Unique Sauer advantages

Gas-tightness

Sauer helium compressors reach a leakage rate of less than 0.1 mbar x l/s.

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
