Description

Attack DP Gasification Boiler

ATTACK DP Profi wood gasifying boiler is designed for the economical and ecological heating of family houses, bungalows, small plants, workshops and similar premises. The specified fuel for the ATTACK DP 45 boiler is dry wood. When the feeding chamber is full, an approx. continuous combustion of 8 to 12 hours is possible.

The “ATTACK DP Profi” wood gasifying boiler is controlled by an electronic regulator which is specifically designed for the temperature control of wood combustion boilers. The regulator keeps a constant check on the water temperature in the boiler and the value is shown on the display. At the same time, it controls the waste gas ventilator and central heating pump.

Models DP 35, 45, 75, 95 Profi
Modern design
Burns soft and hard wood in its large combustion chamber. Fuel mixtures such as coal/wood, briquets, corn cobs and wood/saw dust mixture acceptable.
High combustion efficiency – low fuel consumption
Minimum waste
Simple use and cleaning
Automatic boiler switch-off when fuel runs out
Flue ventilator ensures uniform and effective combustion
Possibility of loading large pieces of wood
Equipped with a cooling circuit against the water in the boiler overheating
