Charging Boilers
Optima Komfort Plus A

DESCRIPTION
Structure of OPTIMA KOMFORT PLUS boilers ensures two-system operation and combustion of all types of fuels - fines in case of firing from top / with operation time up to 20 hours/ and the remaining solid fuels /coal, wood, mix of coal and fines/ in case of firing from bottom. Electronic control of air blowing for combustion, allowing more precise temperature adjustment and increasing servicing comfort, are used in the boilers. Multi-point air supply system to the fuel charging zone increases stability and efficiency of boiler operation.
