Conventional filling
- Filling via tipper fills only approx. 1/3 of the storage area
- Limited storage volume use and more manual redistribution

Vertical refuelling system
With ejector outside
The automatic wood chip refuelling system, vertical (outside), ensures optimum refilling of storage room situations. In addition to the option of an inside ejector, Hargassner also has a self-developed external ejector in its wide range of accessories. A vertical auger with shaft transports the wood chips upwards on the outside of the building and the storage room is filled through a wall opening (minimum 65 cm width and 30 cm height). The adjustable ejector is particularly suitable where an inside installation is not possible, for example with round silos and ground-level rooms with low ceilings.
Outside ejector system
Flow path and operating principle
- Vertical auger with shaft on the outside of the building
- Storage room filling through wall opening (min. 65 cm x 30 cm)
- Adjustable outside ejector with targeted distribution
- Capacity up to 50 m³/h
- Particularly suitable for round silos, flat and low rooms
- No storage room volume loss due to motor height
Conventional filling
- Filling via front loader fills only approx. 2/3 of the storage area
- Material distribution often remains uneven
Conventional filling
- Filling via wood chip blower can create dust nuisance
- Useful storage room volume can remain partially unused
