T-PRO
Solid fuel boiler intended for burning wood chips, briquettes with the possibility of using brown coal.
The steel firebox is three-flow with water-cooled pipes: better combustion and lower consumption!
The large upper door of the boiler, as well as the firebox itself, are specially adapted for burning with wood chips.
The boiler is made of steel sheet of optimal thickness, which guarantees a long service life and resistance to higher temperatures: The sheet thickness of the water wall is 5 mm, according to the requirement of the EN 303-5 standard, while the sheet thickness of parts less exposed to thermal deformations is 3 mm and 4 mm.
Regulation of the operation of the boiler when using solid fuel is through the draft regulator (it is not an integral part of the boiler).
An integral part of the boiler consists of an ashtray, cleaning accessories and a thermometer.
The boiler is suitable for retrofitting a wood pellet burner BIOTHERMEC.
The boiler casing and the boiler boiler are delivered separately and assembled on site.
