Condensing and modulating, multi-burner heat generator in stainless steel AISI 316 L, for indoor and outdoor installation, with protection degree IPX5D; constituted by several large water content preassembled modules, without any hydraulic interception in between. For natural gas or LPG operation.
Output range: from 250 to 1000 kW
- High efficiency thanks to the special patented progressive pipes in stainless steel AISI 316 L, with special multi-fin inserts in Al/Si/Mg
- Large water content modules in vertical shape in order to get the stratification of the temperatures, with two return connections
- Combustion chamber positioned above the tube bundle
- Premix and modulating vertical burner above the combustion chamber, with flame surface in radiating metallic mesh
- Air-gas premixing within the fan, with integral non-return valve and minimum gas pressure switch.
- Ignition and flame control device BMM, NTC sensor for working temperature control and safety thermostat
- Smoke pipes with external diameter 42 mm, endowed with multi-fin inserts in Al/Si/Mg, placed in a vertical tube bundle and tilted of 3° for: a natural outflow of the condensate, absence of wet acidic deposits, exchange surface cleaning, inside water ways driven and braked
- Thermal modules integrally insulated with fiber wool, 50 mm thick, protected with aluminium foil
- Reversible global flow and return connections (for the models 250, 375, 500)
- Reversible global gas connection and smoke outlet for all the models
- Two return connections: for high and low temperature to optimize the heat exchange
- Galvanized casing for outdoor installation and painted with epoxypolyester powders of grey colour
- The construction fully complies with the requirements stated by the EN 303-1
- The surfaces exposed to the fire and smokes are built in stainless steel AISI 316L, according to EURONORM 25 and EURONORM 28
