Oil-free compressors

On-going product development has led to the launch of Boge's second generation air or water cooled SO series oil free screw compressors that are said to set new standards in the 110 to 255kW performance class. In addition to high efficiency and reduced sound pressure levels, there's a new service-friendly layout.

Intake air is drawn from the coolest area to help increase the free air delivery and the minimisation of internal pressure losses has led to greater efficiency, both of which help to improve specific power consumption.

SO-2 models now have a combined sound and pulsation absorber. The design and use of powerful absorbing materials means the range operates with improved sound pressure levels making the new SO series quieter.

Addition of a condensate separator in the intercooler between first and second stage airends is said to mean absolutely safe operation for the second stage in applications where there are low ambient temperatures or where there is high humidity.

The oil cooler is now located in the area beneath the intercooler and aftercooler, improving access.
