The SO series sets standards for efficient and reliable generation of absolutely oil-free compressed air. The intelligent design and innovative cooling principle offer clear advantages in day-to-day operation: lower energy costs, lower maintenance costs and greater reliability!
The water cooled screw compressors in this range use the latest technology to produce oil-free compressed air for sensitive applications - including the pharmaceutical, food and semiconductor industries.

Advantages at a glance:

• Reliable supply of oil-free air thanks to ideal atmospheric separation of the gear unit and the compression chambers through the two-stage air end
• High efficiency due to the precision-engineered asymmetrical screw profile
• Wear-free running due to the use of synchronised rotor gears
• Additional motor reserves for challenging operating conditions
• Long service life of the motor due to installation in the cooling air intake section and PTC resistor protection
• Maintenance-friendly due to intelligent design with components positioned for easy access
• The high-quality materials and fewer wearing parts make for minimal maintenance costs and a long service life
• Available with optional cowl cooler, heat recovery, or HOC adsorption dryer for practically energy-free compressed air drying to -40°C 

With integrated frequency converter:

• Energy savings through minimised idling times and reduced operating pressure
• Optimum adjustment to compressed air demand
• Faster response to changes in demand
• Smooth operation and low compressor wear
• Extended service life
