DemirDöküm MK Boiler

MK Series Boilers

Central Systems

Superior Features

Compact Design

Boiler dimensions are optimum thanks to counter pressure design and products occupy less space in boiler rooms.

Three-way Transitive Smoke Gas Circulation

Thanks to the special design of combustion chamber, horizontal 3-way transition and special retardant design provides higher thermal efficiency and increases product life and efficiency of the boiler in addition to keeping the level of waste gas emissions hazardous for the environment at the lowest level.

Low Temperature Heating

Boiler influent and return water temperatures are adjusted according to varying temperature demands and system requirements, thus energy saving is provided, increasing system efficiency and product life are aimed at.

Jetstream Technology

Cold installation water returned back to the boiler is jet into the boiler. Vacuum impact created by jet system enables the hot water that is about to leave the boiler towards cold water. Hot water is mixed with cold water and boiler return water temperature is thus increased. This way, boiler operates less and fuel saving is achieved.

Flexible Casting Technology

With DemirDöküm’s superior technology, 50% more flexible casting technique provides more durable and long lasting products against thermal shocks.

Fuel Saving with Control Panels

Daily and weekly operating times can be adjusted by DemirDöküm SCP series control panels and the operation of the boilers over the required level is prevented and thus fuel saving can be achieved.
