ATTACK SLX 50 LAMBDA wood gasifier 50 kW

Area of ​​application & Target audience

The ATTACK SLX 50 LAMBDA is a Hot water boiler for solid fuels (wood) with automatic air control via lambda sensor. It is particularly suitable for:

• large apartment buildings

• commercial and industrial buildings

• agricultural estates

• Renovation projects with a sufficiently sized chimney

Preferred fuels are Logs with a moisture content ≤ 25%.

Everyday benefits

The integrated lambda control continuously measures the residual oxygen content in the exhaust gas and automatically controls the air supply. This results in:

• Optimized combustion quality and efficiency

• Fuel consumption reduced

• Emissions minimized

• constant performance values ​​achieved

Even with fluctuating wood quality, combustion remains efficient and controlled.
