Flexilo pellet storage tanks

With a Flexilo storage tank, your pellets are stored compactly, protected from moisture and also cost-effectively. You can specify the installation location. There’s no need for a separate storage room. We can offer you the right version to meet your specific space and pellet requirements.

Pellet silos for all requirements

ÖkoFEN supplies a range of Flexilo storage silos in various sizes. You can choose from a range of pellet tanks in many different sizes, with storage capacity ranging from 499 kg to 12 tonnes.

Flexilo Compact pellet silo with unbeatable storage capacity

The Flexilo Compact storage tank offers 60% more capacity than a conventional pellet storage tank of the same size. Even with a ceiling height of only two metres, you can store up to 8.6 tonnes of pellets. An integral auger for transporting wood pellets to the pellet boiler and the tried-and-tested extension spring system for flexible sloping floors allow the silo to be emptied completely.

Space aplenty for plenty of pellets. Available in many different sizes from 499 kg to 12 tonnes.

Greater filling volume

An intelligent functional concept incorporating extension springs allows up to 60% more pellets to be stored in the same space in the Flexilo Compact.

Thanks to integral auger and elastic sloping floor, pellets are emptied almost completely. Even with ceiling heights of only 2 m, storage of up to 8.6 t is possible.

Incredibly adaptable

The tanks are made of a special polyester fabric interwoven with metal threads. They are dust-tight, permeable to air and anti-static.

They can be sited in boiler rooms or storage rooms. We can offer you the right version, whatever your space and pellet requirements. Special sizes are available on request.

All under control

You can also equip your storage tank with a level sensor to keep you informed of the current stock level.

If the level falls below the minimum defined by you, this information appears on the boiler or as a notification on your smartphone or PC. You are reminded in good time to refill with pellets.

Flexilo Compact - filling quantities for room heights from 185 to 240 cm

ÖkoFEN storage tanks create space. The key technical requirements at a glance.

Size of the storage room

The storage room must be at least 14 cm wider than the storage tank itself. Care must also be taken to ensure that the room is at least 30 cm longer than the tank on the side with the filling unit. The minimum ceiling height is 2 m. In order to utilise the maximum filling capacity, most storage tanks require a ceiling height of 2.40 m. The storage room must be equipped with a 170 cm² vent or a window.

Selection of the tank size

The tank size depends on the building heat load. The following rule of thumb is derived from average heating habits: 1 kW heat load = 400 kg annual requirement of wood pellets

Example: Heat load 12 kW x 400 kg = 4800 kg

Outdoor installation

You can also install your ÖkoFEN storage tank outside the building. The tank then only needs to be protected from sun, wind and moisture with a roof and side panelling.

Pellets are transported to the boiler in this case by the vacuum suction system.
