Boilers type Šukoplam MULTI with power range 25-80kW are specialized boilers ment for production of hot water by combustion of different types of fuel.Boiler construction is completly in accordance with european standard EN 303-5.

                Boiler is constructed as „three drafted“ with one water cooled chamber and flue pipes which means that products of combustion pass water area in three occasions maximasing the heat exchange.First heat exchange is in boiler firebox, mostly by methods of irradiation, through large surface area of boiler firebox, second heat exchange is in the water cooled chamber of the boiler mostly by methods of irradiation and convection, and the third heat exchange is in flue pipes before the flue gasses exit the boiler mostly by methods of coduction and convection.Boiler body is well insulated with mineral wool and boiler sheeting is protected with painting or powder coating processes.

                Boiler is ment for production of hot water in operating mode 110/90ºC and 90/70ºC with maximum allowed work pressure of 2,5bar.

                Boiler is constructed as combined boiler and is ment for combustion of bulk solid fuel (wood, coal) which is manually loaded through spacious middle boiler door or for combustion of pellet, oil and gas by installing the burner on the boiler bottom door.This feature gives versatility to the boiler for combusting different type of fuels and very easy change of fuel in use.

                Installing the pellet, oil or gas burner and installing the turbulators into flue pipes for even greater heat exchange can increase the efficiency of the boiler up to 92%. Automatic controler for boiler work with burners and also turbulators are delivered on buyer demand and are not included in standard boiler delivery.

                Regulation of air flow needed for combustion of chunk solid fuel is done with draft regulator which moves  the flap on the bottom boiler door and by doing so increases or decreases the amount of air needed for the combustion. When using pellet, oil or gas burner regulation of air flow needed for the combustion is done through the burner and boiler automatic controler.

                Protection of boiler from increased pressure is done by installing the safety valve on the appropriate place on the boiler, while protection of the boiler from increased temperatures is done by installing the safety heat exchanger which,if the need arises, cools down the boiler.
