Hot water <strong>boilers</strong>Vitomax 300/200-LWVitomax 200-WS/200-HW0.52 to 20 MWVitomax 300/200-LWThe Vitomax 300/200-LW is a low pressure hotwater boiler <strong>for</strong> permissible flow temperaturesup to 120 °C, permissible operating pressuresof 6, 10 <strong>and</strong> 16 bar <strong>and</strong> a rated heating <strong>output</strong>ranging from 2.1 to 20 MW.The Vitomax 300-LW (Low-NO xseries) isa three-pass boiler with low combustionchamber loading, which ensures cleancombustion with low nitrogen oxide emissions.Easy to service <strong>and</strong> with <strong>high</strong> load capacityExceptional operational reliability <strong>and</strong> a longservice life mark out the Vitomax 200-WS.These are assured through wide watergalleries <strong>and</strong> a large water content withexcellent natural circulation <strong>for</strong> a reliable heattransfer. The additional DHW circulation pipe inthe lower boiler area (shunt pipe) is designed<strong>for</strong> the internal circulation of the boiler waterproviding an optimum heat distribution insidethe boiler.For commercial nurseries:Vitomax 200-WSThe Vitomax 200-WS as three-pass boiler withlow combustion chamber load (< 1.0 MW/m³)was developed specifically <strong>for</strong> commercialnurseries. This low pressure hot water boileroperates in compliance with TRD 702 <strong>for</strong> apermissible flow temperature up to 110 °C <strong>and</strong>a maximum operating pressure of 3.0 bar. Witha boiler efficiency of 94 percent, this boiler isboth economical <strong>and</strong> efficient.The additional DHW circulation pipe in thelower boiler section is designed <strong>for</strong> the internalcirculation of the boiler water, providing anoptimum heat distribution inside the boiler.All connections required <strong>for</strong> facilitating a safetytemperature of 110 °C are already provided onboth <strong>boilers</strong>. No additional intermediate flowpiece is required.1In continuous operation in commercialnurseries, this hot water boiler scores <strong>high</strong>lythrough its easy serviceability on account ofthe water-cooled reversing chambers withoutlining.Finally, the large cleaning door contributesto low maintenance costs. The load-bearingcover on top of the boiler is part of thest<strong>and</strong>ard delivery; it simplifies installation<strong>and</strong> maintenance, <strong>and</strong> protects the thermalinsulation against accidental damage.Vitomax 200-HWThe Vitomax 200-HW is a <strong>high</strong> pressure oil/<strong>gas</strong> hot water boiler <strong>for</strong> permissible flowtemperatures up to 150 °C <strong>and</strong> permissibleoperating pressures of 6, 10 <strong>and</strong> 16 bar –a typical boiler <strong>for</strong> use in district heatingnetworks <strong>and</strong> industrial enterprises.Reliable technologyNo minimum heating water flow rate isrequired <strong>for</strong> the Vitomax. Wide water galleries<strong>and</strong> large water content provide excellentnatural circulation <strong>and</strong> reliable heat transfer– this makes the hydraulic connection easier.Finally, the Vitomax features a low pressuredrop on the hot <strong>gas</strong> side through convectionheating surfaces with large hot <strong>gas</strong> pipes.43Vitomax 200-HWType M72A21 Boiler with load-bearing cover2 Water-cooled burner insertion point <strong>for</strong> lownitrogen oxide emissions3 Large <strong>and</strong> light cleaning doors4 Wide water galleries <strong>for</strong> good naturalcirculation <strong>and</strong> low thermal load
