For over 50 years, Sauer Compressors has been a leader in gas-tight helium compression, offering solutions that prioritize efficiency, safety, and reliability for this finite and valuable resource. Helium’s rarity and high cost make it minimizing leakage essential for companies. This is why Sauer helium compressors are engineered with an ultra-low leakage rate of < 0.001 psi. Designed to handle the unique demands of helium applications, our compressors provide unmatched performance and security, trusted by research institutes, universities, and gas companies worldwide. Backed by Sauer’s global sales and service network, we deliver advanced helium compression solutions that ensure companies can rely on the purity, safety, and retention of their helium assets.
All advantages at a glance:
Gas-tight
Sauer Helium Compressors have a leakage rate of < 0.001 psi
- Gas-tight crank case with double lip seal at the crankshaft
