Boilers with feeder for coal

Agro

AGRO type boilers are equipped with two combustion chamberss - bottom with retort furnace intended for combustion of eco pea coal and upper, full-scale, formed by the fixed water-cooled grate, where coal from thicker assortments and wood can be combusted. Heat exchanger is made of certified boiler sheet of thickness 6 or 8 mm /depending of boiler power/. It is adapted for installation of STRAŻAK (FIRE-FIGHTER) extinguishing system, protecting against flash-back to the fuel feeder.

5 lat gwarancji 5 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler;
