Lagerraum weiter von Heizung entfernt

Lagerraum direkt neben der Heizung


Die KWB Förderschnecke mit Saugförderung eignet sich besonders für weiter vom Heizraum entfernte, längliche Pelletlagerräume. Sauglängen von 25 Meter und Höhenunterschiede bis zu 5 Meter zwischen Heiz- und Lagerraum können problemlos bewältigt werden.


Die KWB Förderschnecke mit Knickschnecke ist die ideale Lösung bei einem länglichen, neben dem Heizraum angeordneten Lagerraum. Die Förderschnecke ist in verschiedenen Längen erhältlich. Das extrem leise Fördersystem ist wartungsfrei, absolut zuverlässig und hat einen minimalen Eigenstrombedarf.

KWB Dust Filter E Plus

KWB Dust Filter E Plus

The KWB dust filter functions on the principle of electrostatic particle separation and removes the fine dust contained in the exhaust gas. The removed filter dust is collected in a generously-dimensioned ash tray which is conveniently and cleanly operated from the front. With the KWB dust filter EPlus, fine dust is no longer an issue, even with changing fuel qualities.

Clean and convenient

Ease of operation is our highest priority, regardless of whether we focus on how to handle the ash container, the system's quiet operation or the intuitive and very simple control of the system.
