  • TP3 LN
  • TP3 LN

Only for CE markets: Sale and installation of TP3 LN boilers (models from 70 to 3200) only for industrial applications or in accordance with EU Regulation No. 813/2013 (Article 1, Comma 2 , Point G)

Hot water generator with pressurised combustion withthree flue gas passes and three-star certified energy efficiency in accordance with directive 92/42/EEC.

Ready for operation in combination with a jet burner on liquid or gas fuel. The arrangement and generous sizing of the combustion chamber guarantee a low heating load and the possibility to be combined with burners featuring technology for the combustion with low polluting emissions.

Range consisting of 20 models with rated outputs from 70 to 3,200 kW.

  • Technical Data

    Boiler body lined on the outside with carbon steel plate protection painted with epoxy powder coat, and consisting of:

    pipe for the second flue pass with intake from the bottom of the furnace, sized to optimise combustion parameters;

    tube bundle for the third flue gas pass located at the top and hotter part of the hot water generator, soas to prevent condensate forming and fitted with steel turbulators to increase convective heat exchange.

    Energy efficiency exceeding 95%.

    Design pressure 6 bars.

    Maximum design temperature 100°C.

    • Floating combustion chamber with cooled end plate, volumetric heating load less than 1.1 MW/m3 to ensure atmospheric nitrogen oxide emissions less than 80 mg kW/h, in combination with suitable burners.

    Threaded fittings up to 240 kW outputs and flanged fittings complete with counterflanges for larger sizes.

    Front door with reversible opening from both sides and innovative closing system with micrometric adjustment on the boiler body. Heat insulation using with material with excellent insulting properties and reduced thermal inertia, protected by refractory material on the furnace side and on the flue gas pass side.

    Heat insulation extended to all parts of the boiler using an 80 mm thick layer of mineral wool on all the plating.
