EKO-CUP V3 steel hot water boilers (heat output range 0,8-1,5 MW) and EKO-CUP SV3 (heat output range 1,5-2,5MW) are engineered to meet heat-ing requirements in middle sized or large premises, or to provide the heat source for manufacturing or processing. This boiler can be installed as a separate unit or as part of a modular set of two or more units. This product is notable for its modern design, for its syn-thesis of modern technologies and high quality materials, as well as for its simple and easy assembly and operation. Well tested development allied to intensive quality control assures that these boilers are safe and reliable. A triple-pass flue gas flow system is the foundation for their low energy con-sumption. A wide range of automatic control devices, delivered as additional equipment, enables the customer to benefit from a fully automatic direct or re-mote controlled heating center.
EFFECTIVEBuilt-in turbulators allow better heat trans-fer from flue gas to boiler water.
REGULATIONThe basic boiler control operates by the operation of a two-burner burner according to the boiler’s default boiler temperature.
ISOLATIONA special feature is the exceptional ther-mal insulation of the boiler.
INSTALLATIONDelivered in parts that allows easy transportation and installation of the boiler.
•Hot water boiler for central heating systems with a triple-pass flue gas flow sys-tem (heat output range 0,8-2,5 MW).•Economical and ecologically attractive, with high efficiency and low NOx content .•A maximum operating temperature of 110°C enables use as a source of heat for manufacturing and processing.•Maximum operating pressure of the boiler is 6 bar, which enables installation into heating systems for tall buildings.•Built in turbulators enable better heat transfer from flue gas to the boiler water, better regulation of gas flows in the combustion chamber, better regulation of the output temperature of flue gas, i.e. high quality balancing between the func-tions of the boiler, burner and chimney.•A large volume of water in the boiler reduces the number of start ups, prolongs the life of the burner and saves energy.•Good design and material choice assure extremely low start-up condensation.•All connections are installed on the upper side of the unit, enabling simple assembly.
•The boiler is delivered with thermal control installed together with connections for an external temperature thermostat, which enables fully automatic regulation of the heating system.•A special feature is the high performance heat insulation.•The blank door of the boiler has prepared mounting holes, enabling attachment of any kind of burner.•The body of the boiler is delivered separately from the casing with thermal insulation which allows easier transportation and assembly.•90° right side and left side opening of the boiler door enables easy cleaning.•The boiler is tested and certified at the Faculty of Engineering in Zagreb and manufactured in accordance with ISO 9001.
