Future-ready with IE4 motors: ESD series rotary screw compressors from Kaeser are now equipped as standard with energy-saving motors and high-efficiency Sigma airends. The prime benefits: even lower energy consumption for significant energy cost savings.
Energy-saving, environmentally-friendly fluid filter
The principles of resource conservation are also consistently applied inside the compressor unit: the environmentally-friendly fluid filter elements now simply sit in an aluminium housing, with no need for a sheet metal enclosure. The filter elements themselves are completely free of metal, making disposal straightforward: at the end of their service life, they can be thermally disposed of without additional pre-treatment.
Controller ensures optimised operation
The advanced “Sigma Control 2” compressor controller provides comprehensive monitoring of the compressor and, if equipped, the frequency converter (SFC variable speed control option). It also enables the compressor to utilise powerful networking solutions and allows straightforward connection to a master control system, such as the Sigma Air Manager 4.0, or to a control centre.
