Another boiler from the DEFRO EKO series - the UNI version has been equipped with the APPS UNI fuel charger. The burner used allows for using different types of solid fuels such as pea coal, qualified fines, biomass in the form of pellet as well as grains, e.g. oat. The burner has been equipped with an innovative solution of secondary charging, which facilitates the process of combustion and makes it more ecological. The combustion chamber has been equipped with ceramic catalysts stabilising the combustion process and making it more effective and efficient. The DEFRO EKO UNI boilers are equipped with an additional cast iron grate, which allows for emergency operation of the device even in case of a power cut. The boilers have been equipped with elements increasing usage safety. Standard equipment is as follows: the FIRE-FIGHTER water quenching system (in case of flame return to the fuel charger pipe) as well as the door-opening sensor. A lamp for the charge container improves the comfort of work. On request, the boiler can be equipped with an innovative controller with a touch screen.

Boiler’s advantages: basic pea-coal fine coal pellet replacement oat coal /nut/ wood, edgings, shavings
Boiler’s advantages: 5-year warranty for heat exchanger tightness, 2-year warranty for other elements and efficient operation of the boiler; the exchanger has been made from certified boiler steel ( P256GH type) of thickness of 6-8 mm, delivered by the following steel plants: Arcelor Mittal Poland S.A, Kraków branch and U. S. Steel Košice s.r.o.;
