PuroWIN
The wood chip heating revolution
With the PuroWIN, we have revolutionised heating with wood
chip. Never before has this fuel been used so cleanly, safely and
intelligently to supply heat. The zero-emission gasification boiler
offers impressively smart and is the first boiler to transport wood
chip utilising a suchtion system.
- Patented wood chip gasification combustion process
- The first boiler that is ready for series production with suction of wood chips
- The only system with dust emissions of less than 1 mg without additional filters

A solution for every storage room
The PuroWIN has a wood chip transport solution for virtually any store room configuration. It can also be used in conventional setups where the boiler room and wood chip store are adjacent to one another. In this case, the wood chip is transported to the boiler via the auger channel. The modular design of the auger transport system allows the length of the augers to be individually adapted up to a distance of 6 m. The agitator in
the storage room is available from 2 to 5 m diameter in steps of 0,5bm. We have the ideal solution for your needs.
Boiler and storage on ground level:
Direct filling of storage room, transport to boiler via auger
Boiler in the basement and storage on ground level:
Direct filling of storage room, link to boiler via down pipe
Boiler in the basement, storage in mezzanine:
Horizontal room clearing to the boiler
Boiler and storage in the basement – variant 1:
Filling of storage room via ceiling-mounted filling auger, transport to boiler via auger
Boiler and storage in the basement – variant 2:
Filling of storage room via ceiling opening, transport to boiler via auger
Flexible transport of wood chip
The PuroWIN is the first wood chip boiler to be able to transport wood chip using a suction system – the only system in the world with this feature. Transport distances of up to 25 m and 7 m high can be handled with ease by the Windhager suction system.
It doesn't matter whether the wood chip is to be transported to the boiler in a straight line or round bends. This means you can easily store fuel in another building.
Only the PuroWIN offers this level of flexibility.
Der PuroWIN...
delivers maximum operating reliability, not just for the boiler itself, but also for the fuel extraction system.
The auger for all scenarios
For the PuroWIN, we have developed an unusual safety auger channel with Side Slide Technology (SST). Depending on fuel, up to 60 percent of the wood chip is transported to the side of the auger rather than directly into it. Foreign bodies and large pieces of wood can cause virtually no harm. The system is also very quiet and smooth-running. Minimal wear and low power consumption are further benefits of the SST auger channel.
Robust agitator protection
The spur gear unit of the agitiator is protected and requires no maintenance and experiences no wear. It is completely reliable and combines high efficiency with great ease of movement. It uses up to 75 % less energy than conventional solutions.
A surround protects the gear unit
The gear unit drives the mixer, compound springs and the entire auger. Unlike the usual setup, this is not attached directly to the floor but is supported by a protective surround. This protects the gear unit from the weight of the wood chip. We've fitted bend protection to the mixer's compound springs of other manufacturers and therefore much more robust.
PuroWIN Cascade
Excellent output with wood chips
The PuroWIN can be connected to two-unit, three-unit and four-unit cascade systems, covering heating requirements up to 400 kW.
In addition, a gas-fired peak load or backup boiler can be incorporated, for example. Specially developed by Windhager, the cascade regulation system constantly checks how many boilers as well as which ones need to be in operation to provide the required amount of heat. Balanced utilisation of the system is also ensured by checking the run times. Thanks to its considerable modulation depth, the PuroWIN cascade operates highly efficiently at a lower output range, too.
Reliable heating
In comparison to a large boiler system, the cascade system is extremely reliable: if one unit fails to heat, you can continue heating normally with the second unit. And service work can be carried out without having to switch off the heating.
