The basic element is formed by two aluminium alloy
castings that, on the smoke side, have dense fins,
with increasing height toward the smoke discharge,
placed in lower part of the casting, in order to increase
its exchange surface.
Inside the castings there are the water channels that,
always with more reduced section, zigzag cross the
casting, granting an exceptional heat transfer from
combustion gases to the water.
Every thermal element is equipped with:
The smoke and acidic condensate of the thermal elements
are collected in a stainless steel tray.
• premix modulating burner
• two stage modulating gas valve
• electronic ignition and ionization
• NTC working temperature sensor
• safety thermostats
• flame sight glass.
Condensing Water Heaters > Modulex EXT Water Heaters
Radiation Combustion
Main protagonist for a perfect combustion and therefore the maximum
efficiency, is the modulating fan (1000-6000 rpm) of which every unit
is equipped.
The number of rpm of the fan, together with the opening of the valve gas
and the flame control, is directly programmed and controlled by the
electronics of every burner (BMM Burner Modular Module) and, in their
turn, they are managed by the E8 controller.
The output modulation depends on the speed of the fan and the difference
between the required temperature, and the maximum one.
Total Premix
The opening of the gas valve is produced by the
in the Cochlea of the fan and the air and gas mixture
happens inside before being introduced to the combustion
chamber (premix).
This perfect “mixing” combines the air and gas in parts
always in proportion through the multi-gas burner.
This system, characterized by the issue of electromagnetic
radiations, is most efficient for the transmission of thermal
energy.
The wide surface, on which the combustion happens,
guarantees:
•
long lasting burner structure
quiet operation
simple maintenance thanks to the use of few components
and easy accessibility
larger quantity of transmitted energy in comparison to a
traditional burner with the same flame temperature
absolute working safety for the absence of turbulences
very small production of pollutants due to the complete
oxidation of the gas molecules;
• excellent combustion efficiency: maximum CO2= 9,3%
• efficiency optimization thanks to the low
smoke temperature and the limited “air excess”
• very low pollutant emissions: NOX<53,8
mg/kWh (pondered value according to
• reduced turbulence
with the following advantages:
“Venturi
effect”
low combustion temperature
EN 15420).
The valve is directly mounted on the fan.
Inside its volute the air/gas mixing
calibration takes place.

After the time “T1” from the starting, MODULEX EXT succeeds in satisfying the 30% of the load unlikea traditional boiler 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 to 70%.
This clearly displays the speed of the Modulex EXT Boiler
Radiation Combustion
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 boiler are
a must in today's world.
This function enables you to drastically reduce the
number of switching ON and OFF of the boiler.
(Possible customization of the requested output).
• Higher efficiency and lower flue losses when burner
is OFF.
• Longer lasting of the parts in movement and of the
ignition systems.
On average a boiler operates at 50% of the thermal
need of the C.H. 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.
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 C.H. and D.H.W. production, with a lower noise
level than the traditional boilers.
Setting option according to the thermal needs of
the C.H. system

Very low water content and high modulation

Eco - Logic
MODULEX EXT has a certified efficiency
that, for all models above 350 kW, when
working in condensation, progressively
increase up to when the output
is reduced.
The genius of the thermo-controller E8
is that it keeps ON the
as possible, working at the
(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.

Primary Rings withMixing Header
MODULEX EXT is a low water content boiler and therefore a
low thermal inertia boiler:
• high speed of output supply
• immediate answer to the load variations
• minimal heat losses.
The great variations of flow rate and temperature that follow
are, therefore, conveniently balanced by the so-called
hydraulic separator, before reaching these ultramodern
“heating engines”.

The balance between supplied output
and the water flowrate is controlled via
the modulating pump. The BCM card
collates the data relating to flow return
and the low water level, and depending
on this it will either increase or decrease
the flowrate to suit the thermal jump
requirement.
The Modulex EXT will always operate
