Wood chips hot air heating

Our wood chips hot air stoves are available from 150 kW to 2500 kW nominal heat power. In contrast to cord firewood hot air stoves, wood chips based hot air stoves are fully automatic. The devices are ready-to-use systems and are portable as well.

Thus, our clients are able to use the hot air stove at various locations. The integrated day tank ensures long-lasting and even heat output. From 750 kW, the fuel tank is constructed externally.

very efficient and CO2 neutral

Wood chips hot air heating LA150 and LA250

Our wood chip hot-air stoves in the 150 kw and 250 kw performance classes have reached a further evolutionary stage.
A comprehensive redesign of the combustion system has resulted in numerous advantages. Record breaking emission values enable the generators to be conveyed in almost all European countries without the need for additional filter systems.

The new, fully automatic fuel recognition system not only sets new standards in operating convenience, but also provides even higher efficiency and thus less maintenance intervals.

\

LA150 and LA250 - Both units hardly differ from each other in their external appearance.

\

Combustion chamber

A movable step grate operates inside the combustion chamber.

\

Touch control

The entire wood chips series is delivered with a state-of-the-art touch control system.

Wood chips hot air heating LA750

The LA 750 is designed for really large heating and drying ideas and offers all the intricacies of modern combustion technology. The LA 750 is in the same way equipped with all the components like the smaller types, but in this case and due to the portability and the fuel consumption, the storage tank has been transferred externally into a portable container.

Wood chips hot air heating LA2500

The LA 2500 combines the latest technology with superior heating power! The step grate firing with integrated pre-drying processes wood chips of G100, W40 quality without any problems.

With the 2500 kW, up to 100,000 Bm3/h can be continuously fed into the heating or drying process.

Flue gas-air heat exchanger

High performance air heat exchanger

The conveyor fan draws in fresh air. This is fed through the air heat exchanger. Thus, the air is warmed up and is 100% emission-free. Since there is no transition to water, very high discharge temperatures are possible.
