Wood Pellet Fuel for Organic Energy Biomass Boilers and heating systems

FleXILO® Compact - storage and boiler fuel delivery systems

Our own wood pellet storage system FleXILO Compact allows you to store pellets in our own FleXILO tank, with pellets being fed to the boiler by an auger screw or via a vacuum suction system.

The FleXILO storage tank is a new innovation for OkoFEN wood pellet boiler systems as it provides an ideal fuel solution for storage rooms with less space and low ceilings.

A new vibrating conical extractor enables about 20% more storage capacity.

Specially important for renovated buildings, the new tank with 1600mm height is suited for the low cellar ceilings.

Flexilo Auger Delivery SystemFleXILO with Auger Delivery

The auger delivery system is the most economical solution but can only be used where the FleXILO is adjacent to the boiler.

The auger can be installed on 3 different sides and is pivoted from 20° to 35°. The burner can be fitted to the right or the left.



FleXILO with Vacuum Suction Delivery


Flexilo Vacuum Suction deliveryPellets may be delivered from the FleXILO to the boiler using a vacuum
suction system. The maximum distance in this case is 20m. The vacuum suction system is used where an auger delivery system is unsuitable
eg. long distances or difficult routes between the FleXILO and the boiler.
