Lead recycling with volume-flow-controlled compressed air station

摘要

With a new low-pressure compressed air station incorporating six speed-controlled, turbo-compressors work, the Weser-Metall GmbH lead works in Nordenham saves up to 600 000 euros per year in energy costs. Key feature of the compressor is its sophisticated control: the control system uses the volume flow rate as the command variable and not, as otherwise usual, the pressure.
