Modulex EXT brochure_3.0
Modulex EXT Condensing Water Heaters Output Flexibility and Efficiency The MODULEX EXT exceeded all industry requirements when it was first conceived over a decade ago. These days the high standards and benchmark qualities of this groundbreaking heater are a must in today’s world. Temperature (ºC) 80 70 60 50 40 30 20 Comparison of the steady state condition reaching time between a modulex and a high intertia/water content heater Setting option according to the thermal needs of the central heating system This function enables you to drastically reduce the number of switching ON and OFF of the heater (Possible customization of the requested output) Advantages: • Higher efficiency and lower flue losses when burner is OFF • Longer lasting of the parts in movement and of the ignition systems Very low water content and high modulation speed with maximum output ratio up to 1:54 On average a heater operates at 50% of the thermal need of the central heating installation and can descend below 30%. MODULEX EXT adjusts in real time the output to meet demand, because it is not influenced by the thermal inertia, thanks to its low water content and, being equipped with modulating pump, it further reduces the electricity used. Class A, variable speed, electronic pumps, for the maximum condensate production This function promotes the production of condensate and therefore the fast economic recovery of the investment. All this in order to offer the user the possibility to save with the maximum comfort both, for central heating and D.H.W. production, with a lower noise level than the traditional water heaters Nominal Load 100 (%) Effciency (%) 10 100 90 80 70 60 50 40 30 20 10 110 108 106 104 102 100 98 96 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 Time (min) T1 T2 T3 T4 Time MODULEX Ext Low Water Content Heater Modulating flow rate pump High Water Content Heater After the time “T1” from the starting, MODULEX EXT succeeds in satisfying the 30% of the load unlike a traditional heater that, in the same time, is just at 15%. After the time “T2” MODULEX EXT is at 50% of the load, while the traditional one is at 30%. After the time “T3” MODULEX EXT is at 100% of the load and the traditional one is only at 70%.

The genius of the thermocontroller E8 is that it keeps ON the greatest number of elements as possible, working at the smallest possible output (as shown in the examples beside). The system will always work in the conditions of maximum possible efficiency, independently from the supplied output. When the requested output is less than the capacity available the design of the Modulex regulates evenly reducing the output of each module to suit. Once the minimum level for a module is reached it is disabled in cascade sequence. This modular system is such that as the number of modules used decreases - the efficiency increases. The flexibility of this modular conception is ground breaking and brings vast cost savings through increased efficiency. To avoid one element module being over used more than others, the thermo-controller automatically alternates usage of all element modules evenly.

MODULEX <strong>EXT</strong> has a certified<br />
efficiency that, for all models<br />
above 350 kW, when working<br />
in condensation, progressively<br />
increase up to 109% when the<br />
output is reduced.<br />
The genius of the thermocontroller<br />
E8 is that it keeps<br />

elements as possible, working at<br />
the smallest possible output (as<br />
shown in the examples beside).<br />
The system will always work in the<br />
conditions of maximum possible<br />
efficiency, independently from the<br />
supplied output.<br />
When the requested output is less<br />
than the capacity available the<br />
design of the <strong>Modulex</strong> regulates<br />
evenly reducing the output of<br />
each module to suit. Once the<br />
minimum level for a module is<br />
reached it is disabled in cascade<br />
sequence.<br />
This modular system is such<br />
that as the number of modules<br />
used decreases - the efficiency<br />
increases. The flexibility of this<br />
modular conception is ground<br />
breaking and brings vast cost<br />
savings through increased<br />
efficiency.<br />
To avoid one element module<br />
being over used more than<br />
