The MKK series are boilers which work with manuel fuel loading principle, fully electronic equipped with fans. It is produced in suitable capacities for individual use as well as for centralized system use. Wood, coal, mining coal and lignite coal can be used as fuel. Hot water for use can be provided with inserted boiler. The heat transfer surface is high. Heat losses are minimized by high heat insulation. With the advanced electronic control function, the combustion air is adjusted according to the amount of fuel. Thus, more energy flow into the chimney and the burn up the fuel is prevented.

Full Automatic

• The fan speed is automatically adjusted withwith integrated electronic circuit system according to the chimney status
• The water temperature in the system is set from the digital display on the device.
• When the fuel in the boiler is completely exhausted and the system temperature decreases below 25 degrees, device switches itself off automatically.
• Energy saving is provided with wet rotor, 3 speed step circulation pump at desired flow rate.
• Thanks to specially designed flame breakers located inside the smoke pipes, the flue gas temperature is reduced to nominal values and the efficiency of the device is increased at the highest level.

Full Safe

• The safe working protects the system against overheating.
• Since the input and output of the boiler are controlled by the electronic circuit system, possible faults are minimized.
• Safe working feature in case of power cuts thanks to the use of open expansion that is compulsory to use.
• 3 years guarantee, widespread service organization
• CE Certificate with Approval of European Union Standards

Practical Use

• The ergonomic design of loading, cleaning and discharge flaps provides ease of use.
• The air sent to the combustion chamber by the fan  ensures  clean, controlled and fully burning of the coal.
• Easy boiler cleaning with special design covers.
• Opportunity of cleaning the boiler in short time with practical ash cleaning mechanism
