Precision Compression for High-Integrity Gases.

The HAUG.Pluto series offers specialized gas recovery and booster compression solutions for applications requiring absolute integrity, including helium, SF6, oxygen, and nitrogen. Designed with a hermetically sealed, wear-free drive, this compressor features an in-house HAUG Sauer innovation—an electric motor within the gas compartment powered through a gas-tight connection for reliable performance up to 304 psi(abs) suction pressures. Ideal for OEM integration, the HAUG.Pluto series is available in modular configurations for tailored, cost-effective solutions. However, it is not suited for explosive atmospheres.

 Outstanding characteristics: 

• Oil-free, dry-running piston compressor with gas-tight integrated motor
• Ultra-low leak rate (< 0.0001 mbar l/s) for environmental safety
• Air-cooled with motor powers from 0.5 to 2.2 kW
• Rotary speeds from 970 to 1700 RPM
• Suction pressure up to 304 psi(abs), discharge up to 884 psi(abs)
• Single-cylinder, 1-stage compression with modular configurations
• Flow rates up to 10 Nm³/h (atmospheric) and 50 Nm³/h (booster)
• OEM block version for integration in custom systems
• Quiet, robust, and compact design suitable for direct workplace installation
• Foundation-free installation for space-saving setups

Applications: 

• Oil-free booster compression of nitrogen and air (CDA = Clean Dry Air)
• Oil-free recovery and compression of SF6 gas
• Oil-free booster compression and recovery of helium
• Oil-free compression of other gases such as refrigerants, argon and carbon dioxide
