DPX COMBI PELLETThe new boiler line ATTACK DPX 45 COMBI PELLET is equipped with the more efficient tubular exchanger flue gas – water. Special movable turbulators installed inside the exchanger serve to brake and to make the turbulent flow of the flue gas through the exchanger. Thereby it comes to higher heat transfer through the steel exchanger wall into the heating water. Turbulators also enable easy exchanger cleaning. The clean exchanger reaches the most effective operation parameters – the high efficiency.

From technical view it is a boiler line with high efficiency, low flue gas temperature and more effective combustion process. Achieved efficiency of the ATTACK DPX boiler is over 90 %. By installation of more efficient boiler of the ATTACK DPX line it comes to significant decrease of the operating costs, projected into the fuel savings, in comparison with less efficient boilers that combust same fuel.From the social-wide view, it is an enviroment-friendly source, combusting wooden biomass, which is a kind of CO2-neutral fuel.

ATTACK DPX COMBI PELLET

The warm water boiler ATTACK DPX COMBI Pellet is a modern heat source with new construction of heat exchanger. the prescribed fuel is wood and pellets – if the automatic stainless steel burner is installed. This innovative solution brings higher comfort thanks to the automatic pellet burner, which is simply installed in the boiler, and the advantage of the cheapest heat energy gained from wood in the wood gasifying boiler.

By installation of the burner into the steel body of the boiler ATTACK DPX you get the combined boiler for solid fuel and
pellets
with adjustable output, automatic grate cleaning, automatic start and termination of the burning process. The pellet burner is placed on a movable construction, which enables to insert the boiler easily into the upper door of the boiler and to
remake the wood gasifying boiler into the pellet boiler. if the burner is not disposable, the burner can be simply dismantled and the boiler can be used as a standard wood gasifying boiler.

The boiler is controlled by the PROFI „PID“ regulator and burner electronics. Both regulators can be turned off by the main switch, according to the fuel used. It is possible to choose the burner of 8–30 kW or 15–50 kW output. The boiler is  intended for economical and ecological heating of dwelling houses, cottages, small factories, workshops and similar objects.
