ATTACK SLX 45 LAMBDA wood gasifier 45 kW

Area of ​​application & Target audience

The ATTACK SLX 45 LAMBDA is a Hot water boiler for solid fuels (wood) with automatic air control via lambda sensor. It is particularly suitable for:

  • large detached houses

  • Apartment buildings

  • commercial 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 adjusts the air supply. This results in:

  • Optimized combustion quality and efficiency

  • Fuel consumption reduced

  • Emissions minimized

  • stable performance values ​​achieved

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


Technology & equipment

  • Boiler type: Wood gasification hot water boiler

  • Power: 45 kW

  • Lambda sensor for automatic air control

  • Fan-assisted combustion

  • Turbulators in the tube heat exchanger

  • Thermal safety device required

  • Maximum operating pressure: 2.5 bar

  • Minimum chimney diameter: 150 mm (200 mm recommended)

  • Recommended chimney draft: 23–30 Pa

To ensure a long service life, a return temperature above 65 °C must be maintained. Recommended boiler temperature: 80–85 °C.


Efficiency & Environment

The ATTACK SLX 45 LAMBDA meets the requirements of EN 303-5:2012 for boilers of fuel class A.

Measurement values ​​according to the information sheet:

  • Nominal heat output: 45.5 kW

  • Partial load (30%/50%): 20.2 kW

  • Efficiency at rated power: 83.3%

  • Efficiency at 30%/50%: 84.8%

Lambda technology supports clean and stable combustion.


compatibility & System integration
