M series boilers with “volcanic” fuel supply

MK series boilers are used for heating of large sized residential and industrial premises and supplying heat for technological needs.

MK series boilers are to be installed on or near combustion chamber. Enforced circulation pumps are mounted on the servicing door shielding.

Heat exchanger may be delivered with pneumatic cleaning system (optional).

Boilers may be delivered with heat insulation or corrugated steel shielding or it may be mounted in the heat plant.
