• High efficiency over the complete control range
• Converter operation to continually adapt the volume flow to the currently required fluctuating compressed air demand
• Smaller screw blower footprint
• Lower maintenance costs

Development of a high-efficiency HBS 1600 screw blower in the power range from 132 up to 250 kW with a new variable-speed drive system from Siemens.

• SIMOTICS SD next generation motor (1LE5) FS315 in the newly developed motor design with high quality materials
• SINAMICS G120 converter – user-friendly as a result of its modular design. The new FSG frame size of the PM240-2 Power Modules. The new PM240-2 Power Module can be ordered as standard in compliance with Category C2 – and has an integrated DC link reactor.
• Drive system comprising motor and converter, optimized to address the specific application – for perfect controllability and a high system efficiency (IES2) in compliance with EN50598
