SO Series from BOGE provides efficient oil-free compressed air

Thanks to the absolutely oil-free compression principle, BOGE's new SO series is suitable for generating oil-free compressed air in particularly sensitive areas of production, such as the pharmaceutical, food and drink, and semiconductor industries. BOGE has now thoroughly reworked the water-cooled screw compressors in their 45-90kW range. The new screw compressors use up to 8 per cent less energy while still generating up to 6 per cent more compressed air. Compressors in the SO series are also up to three decibels quieter in operation. BOGE has designed all compressors in this range with IE3 premium efficiency class motors, thereby saving energy right from the very first minute of operation, and ensuring long-term generation of a sustainable, cost-optimised supply of compressed air.

The use of a two-stage airend, with a low pressure and a high-pressure stage, is responsible for the very low specific power consumption of these compressors. The rotors are finished with a durable coating that prevents the rotors and housing from corroding.

All components are easily accessible and are positioned in the compressor's cooling air stream. The new SO series has a small footprint, as the side doors can be removed and so only require minimal clearance at the sides. The high-grade materials used, as well as the reduced number of wear parts, cut maintenance costs and prolong service life. A radial fan is used to vent the hood, providing a powerful intake of air that allows longer exhaust air ducts to be used, and making the compressor quiet in operation. All models are also available with an optional cowl cooler or heat recovery system.

All 45-90kW-rated models in the SO series are also available with frequency control to match compressed air output to the actual demand at any time. In peak load operation, or where compressed air demand fluctuates, or storage volume is limited, this has the virtue of appreciably lowering energy costs, since the amount of free air delivered by the compressor is adjusted by continuously varying the motor speed. This saves wear and tear on materials, minimises maintenance costs and reduces reaction times in operation.
