HAUG Gas piston compressors with magnetic coupling

Only-gas-tight biogas compressors help the environment by ensuring that biogas also remains environmentally-friendly.

Even small gas leaks can have 23 times the environmental impact as CO2 in

the atmosphere. Therefore, when planning a biogas plant, always ensure that biogas plants with

compressors are designed to be technically sealed.A gas piston compressor with magnetic coupling

best meets this requirement.

HAUG Biomethane compressor (natural gas compressor) for feed-in to the natural

gas network (Final pressure of up to 85 bar)

■ Oil-free compression

■ Sturdy, water-cooled cross-head construction

■ Piston road seal with gas recovery

■ Speeds of up to 800–1250 min-1 ■ Quiet and virtually vibration-free

■ Installation without the need for a foundation

■ Simple and cheap to service and maintain
