Leak-Free Reliability, Decades of Excellence.

The HAUG.Sirius series is a proven choice for the compression of air and gases, trusted since 1973 and refined over decades to meet evolving industry needs. Equipped with HAUG Sauer’s proprietary magnetic coupling, the Sirius series provides leak-free compression with a gas-tight, wear-free drive, supporting suction pressures up to 449 psi(abs). Engineered for permanent hermetic sealing, these compressors deliver exceptional energy efficiency and performance without sealing gas or gas loss, making them ideal for applications where reliability, efficiency, and low maintenance are essential.

 Outstanding characteristics: 

• Oil-free, dry-running piston compressor with magnetic coupling for gas-tight operation
• Leak rate < 0.001 mbar l/s, environmentally friendly and efficient
• Air-cooled or water-cooled options available
• Motor power from 7.5 to 30 kW with speeds from 970 to 1450 RPM
• Suction pressure up to 449 psi(abs), discharge up to 1465 psi(abs)
• Flexible configurations: 2 to 4 cylinders, up to 4-stage compression
• High flow rates up to 400 Nm³/h (atmospheric) and 1000 Nm³/h (booster)
• Explosion-proof versions (ATEX zone 1 or zone 2 compliant)
• Robust, compact, and foundation-free design for versatile installations

Applications: 

• Carbon dioxide recovery, and carbon dioxide compression of supercritical CO2
• Nitrogen inert gas supply during ESD (Emergency Shut-Down)
• Recovery of Natural Gas (leakage gas)
• Oil-free booster compression of oxygen
• Oil-free booster compression of nitrogen and air (CDA = Clean Dry Air)
• Oil-free recovery and compression of SF6 gas
• Oil-free booster compression of natural gas and biomethane
• Oil-free compression of noble gases such as helium, argon
• Compression of refrigeration gas for example C3F8, R410 or ammonia
• Compression of syntheses gas for production of methane and hydrogen as well as power-to-gas applications
