Heat exchanger cleaning
The automatic heat exchanger cleaning saves material and ensures a consistently high level of boiler efficiency and long cleaning intervals. The recumbent 3-way pipe heat exchanger offers a generously proportioned water capacity.
Underfeed combustion chamber
The combustion retort is a 15 mm thick steel construction with completely automatic ash removal and a standard ash container for convenient disposal. Radiant curved structure made of individual stone segments and variable flame passage made from high-temperature ceramic cement. A 4-sided vented underfeed combustion chamber ensures efficient and clean combustion. Durable boiler housing made from high quality materials.
The grate bars of the underfeed retort are made from high-temperature-resistant cast stainless steel with a chrome content of 27%, guaranteeing a long service life.
High level of convenience thanks to optional, temperature-controlled ignition fan for automatic ignition of the fuels.
Screw stoker and ash removal unit are driven by high quality geared motors made in Germany.
