Stainless steel modular condensing modular unit


Stainless Steel

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 moduls, without any hydraulic interception in between. For natural gas or LPG operation.
• Max. working pressure: 5 bar
• 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 moduls 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 moduls 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
Panel board:
• Electronic regulator HSCP, water pressure gauge and On/Off switch
• Managing up to a maximum of 12 fully independent heating circuits and of a domestic hot water storage tank
• Possibility of management of D.H.W. recirculation pump
• Heating zone management: MULTIFUNCTION CARD: SHC (“Slave Heating Controller”): CH, DHW and auxiliary resources: temporized relays, solar storage tanks.
• Local e-BUS interface
• Remote interface for: data acquisition, parameters setting, 2 inlets for outer and room temperature sensors
- Analogical outlet 0
