Boge presents the 61-2 W to 126-2 W water-cooled screw compressors in the SO series. Boge has now carried out a substantial overhaul of the 45 to 90 kW class. The results can be seen for themselves: the new screw compressors are quieter and consume less energy. Due to the completely oil-free compression process, this series is particularly suitable for sensitive production areas such as in food and semiconductor sectors, breweries or in the pharmaceutical industry. All eight models are now available with fixed speed and with an integrated variable-frequency drive, and are distinguished by their clearly-arranged structure and intelligent overall concept.
