Oil/gas boilers for medium and high output

Large steel boilersHot water boilersVitomax 300-LT1.86 to 5.9 MWSets new standards: Vitomax 300-LTThe Vitomax 300-LT sets a new standard in thisoutput range: as a low temperature three-passboiler with multi-layered convection heatingsurfaces made from Duplex pipes; with lowcombustion chamber load. This boiler ischaracterised by high standard efficiency andlow emissions, as well as high serviceability.One typical application would be heating anapartment block where the system is operatedin modulating mode, subject to outsidetemperature.Finely honed technologyThis boiler requires no minimum heatingwater flow rate – wide water galleries andlarge water content provide excellent naturalcirculation and a safe heat transfer. Thissimplifies the hydraulic boiler connections.No additional intermediate flow piece isrequired. All necessary connections for asafety temperature of 110 °C are already fittedto the boiler.Further characteristics of this finely honedboiler technology are the low pressure dropon the hot gas side as a result of convectionheating surfaces with large hot gas pipes;low radiation losses through a 120 mm thickcompound thermal insulation and the watercooledfront and rear reversing chambers.Duplex pipe with multi-layeredconvection heating surface for highoperational reliability and a longservice life12534Vitomax 300-LTtype M3431 Boiler with load-bearing cover2 Duplex pipe with multi-layer convectionheating surface3 Water-cooled front hot gas reversingchamber4 Large flame tube for clean combustion5 Wide water galleries for good naturalcirculation and low thermal load
