ATTACK SLX 35 PROFI wood gasifier 35 kW

Area of ​​application & Target audience

The ATTACK SLX 35 PROFI is a Hot water boiler for solid fuels (wood) With manual loading. It is particularly suitable for:

• large detached houses

• Apartment buildings

• agricultural or commercial outbuildings

• Renovation projects with a sufficiently sized chimney

The preferred fuel type is Logs with a moisture content ≤ 25%.

Everyday benefits

The wood gasification principle ensures a two-stage combustion process with high energy yield. First, the wood is gasified, then the wood gases are combusted at high temperatures. This produces:

• stable power output

• efficient fuel use

• reduced CO and dust emissions

• consistent heat supply

The integrated turbulator lever allows for regular cleaning of the heat exchanger without complex disassembly.

Technology & equipment

• Boiler type: Wood gasification hot water boiler

• Fuel feed: manual

• Adjustable primary and secondary air
