Charging Boilers

Delta

DELTA boilers are intended for combustion of hard coal and firewood. Combustion process is mechanically controlled using knob of lifting flap in ash-pan doors. Moreover, adjustable flap for adjustment of inflow of secondary air is located in charging doors. This solution significantly improves course of combustion process and parameters of flue gas emission. To also possible to adjust combustion process using draught regulator. Furthermore, boilers are factory adapted for assembly of fan and electronic controller. The advantage of the boiler is capacious combustion chamber ensuring many hours of equipment operation and large charging doors facilitating charging of fuel.

4 lata gwarancji na szczelność wymiennika ciepła, 2 lata na pozostałe elementy i sprawne działanie kotła. 4 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler.
