This oil-free screw compressor aims for low cost of ownership
The SO-3 oil-free screw compressor (photo) achieves peak delivery rate values at lower specific power consumption and has lower total costs over its full lifecycle, according to a total-cost-of-ownership evaluation. The SO-3 has further advantages, the company says, including a large control range, quiet operation, low maintenance and the option to recover heat from hot water temperatures of up to 90°C. The energy efficiency of the SO-3 is said to be best in class, with a wear-resistant design and an integrated IE4 drive motor. The efficiency is further increased by the cooling system, which has low compression and output temperatures. And although the screw compressor is compact, the components are easily accessible for maintenance purposes, the company says. Specific sound insulation measures have been implemented to effectively reduce noise levels. The compressor is available with frequency control and heat recovery, to increase efficiency. — BOGE Kompressoren Otto Boge GmbH and Co. KG, Bielefeld, Germany
