DP Standard

Description
The ATTACK DP 35 STANDARD wood gasifying boiler is intended for economical and ecological heating of the family houses, small plants, work stations and similar objects. Wood is the main fuel for the ATTACK boilers. By full utilization of the feeding chamber there is possibility of the continual burning for 8- 12 hours.

Modification ATTACK DP STANDARD
The wood gasifying boiler ATTACK DP Standard is controlled by the boiler and the flue gas thermostat.

Main Advantages of ATTACK DP Boilers
The wood gasifying boiler ATTACK DP is a modern boiler that gets maximum from wood thanks to its technology and saves the environment by ecological combustion. The wood is a favourite fuel, as it produces comfortable warmth and grows right outside your door. The boiler body cooled by water is the basic part of the boilers ATTACK DP. The welded part is made from steel plates of 6 mm thickness. The exchanger can be reached by opening the feeding door, in order to enable easier cleaning.

The manufacturer basically adjusts the flap for primary and secondary air. The primary air comes into the feeding chamber, the secondary air flows into the nozzle. Gasification of wood and the following combustion of the wood gas ensures optimal burning of all combustible contents. The combustion is regulated by the flue gas fan. Boiler body is isolated by a mineral wool. The boiler covering is treated by a powder paint.
