Hydrogen Compressors
Compressors from the HAUG product line stand out by their oil-free and hermetically gas-tight design.
In 1989, HAUG hydrogen compressors were used for the first time in a solar energy demonstration project in Germany. Over the past 35 years, the machines have been continuously improved and have set new standards in the industry. As the compressors are completely dry-running and oil-free, there is no danger of oil-vapour contamination of hydrogen and the equipment downstream. Due to the unique combination of high-pressure cylinders with HAUG NanoLoc design, the HAUG Sirius series can reach final pressures up to 450 barg. The compressors are particularly compact and can be operated very efficiently thanks to a variable inlet pressure.
