Vacuum principle and automatic switch-off
The vacuum principle for the pneumatic waste transport of particles in ducts in combination with the automatic switch-off, are the new systems developed by Hunkeler Systeme AG. As a resulte, it has a strong impact on energy consumption. Thanks to an automatic switch-off, the fans working in negative pressure are only in operation when waste has to be extracted on the production lines. If there is no production on one or more lines, the automatic switch-off puts the fans in stand-by mode.
