Haug Neptune Series: t/m 101 bar

Haug Neptune Series: t/m 101 bar


The HAUG.Neptune series is used for the compression of all gases. Individual customer specifications and explosion protection requirements can be met by using magnetic coupling.


HAUG.Neptune compressors with magnetic coupling are a development by HAUG Sauer that enables permanent gas-tight compression without leakage. This hermetically sealed and completely wear-free drive was first used in a reciprocating compressor in 1989 and can be used for suction pressures up to 14 bar (abs).

The modular HAUG.Neptune 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 energy-optimised solutions.
