Modulex EXT - Condensing Boilers<br />
Pre-assembled Thermal Elements<br />
MODULEX EXT is an assembly of thermal modules, together<br />
making a complete unit. Every unit is constituted by preassembled<br />
thermal elements, in Al/Si/Mg. Every element<br />
supplies, in continuous and progressive way, from 12 to 50<br />
kW for the models up to 350 kW, and from 22 up to 108 kW<br />
for larger models.<br />
More than 10 years experience assure:<br />
• Resistance to the corrosion of the acidic condensate<br />
• Very high thermal efficiency<br />
The basic element is formed by two aluminium alloy<br />
castings that, on the smoke side, have dense fins, with<br />
increasing height toward the smoke discharge, placed in<br />
lower part of the casting, in order to increase its exchange<br />
surface.<br />
Inside the castings there are the water channels that zigzag<br />
cross the casting, granting an exceptional heat transfer<br />
from combustion gases to the water.<br />
Every thermal element is equipped with:<br />
• Premix modulating burner<br />
• Two stage modulating gas valve<br />
• Electronic ignition and ionization<br />
• NTC working temperature sensor<br />
• Safety thermostats<br />
• Flame sight glass<br />
The smoke and acidic condensate of the thermal elements<br />
are collected in a stainless steel tray.<br />
