Power outputs from 15 - 50kW

DPBI range of multi fuel wood pellet boilers, are the biggest and heaviest in size per their power output when compared to other brands of pelletized fuel burners we currently stock. These units are tested to over 30% of their stated output and come equipped with variety of electronic aides to boost their reliability and efficiency.

The DPBI biomass boilers are capable of burning variety of pelletized fuels, including wood pellets, small pea coal, slack and some grains. They are also able to burn solid fuels like wood, logs, peat, turf, coal and other wood originating products, when loaded manually through middle door. Please see the cut away diagram.

The pelletised fuel of no more than 20mm cube is stored in a hopper, rigidly mounted on the side with auger delivering in to the lower centre of the fire box chamber where air is being injected from surrounding air jets. These units, similarly to other boilers in our shop, after completing burn, the remainder of ash falls down on to tray below.

DPBI models in this range come equipped with touch screen colour display computer, mounted on top. The controller operates range of parameters in various modules like self ignition system, air fan, auger supply, multi water pump control and has ability to link with oxygen sensor as well as a gsm modem.
