Haug Mercure Series

Haug Mercure Series: t/m 101 bar


The HAUG.Mercure series is used for gas recovery and booster compression of gases such as helium, SF6, oxygen, nitrogen and natural gas, as well as for booster compression of compressed air.


HAUG.Mercure compressors have the electric motor in the gas compartment. The electric motor is powered via a gas-tight connection in the crankcase. This design, developed by HAUG Sauer, ensures permanent gas-tight compression without leaks. This hermetically sealed and completely wear-free drive was first used in the HAUG.Mercure compressor in 1990 and can be used for suction pressures up to 16 bar (abs).

By using special measures, the HAUG.Mercure compressor can also be used for dry and explosive gases such as natural gas.

The HAUG.Mercure compressor can also be used for SF6 gas and with delivery "Incomplete" for OEM applications, with integrated cooler above the electric motor and minimal piping and instrumentation for integration into an OEM system.

The modular HAUG.Mercure compressor concept allows highly individual and cost-effective adaptation of the compressor configuration to customer requirements. This allows the development of technically
technically, commercially and energetically optimal solutions.
