TECHNICAL FEATURES

• MODULEX is a compact, gas fired, Low NO

, condensing

boiler, made up by one sectional boiler body,
This boiler body consists of two or more modules (from 4 to
8), which cannot be separated from each other, being un-
der the same protecting casing, and are set to operate se-
parately or in cascade. These modules are connected to a
single smoke exhaust manifold and are controlled by a
single microprocessor, which manages completely the tem-
peratures from the point of view, both operational and sa-
fety.

• Efficiency at full load with temperature 30/50°C = 103%.

At part load (30% of the nominal) with 30°C return tempe-
rature = 108,3%.

• Efficiency Class:
• Each module, is composed of a combustion chamber, me-

tallic fiber pre-mix burner, modulating fan, gas valve, igni-
tion ele ctrode, flame detection, NTC sensor for manage-
ment control (BMM), local temperature control and afety
thermostat.

• Each single boiler is equipped with NTC sensors for global

temperature control on the flow and return manifolds.

• Integral, non allergic, synthetic wool insulation.
• Fully pre-mixed, radiating, modulating, metallic sponge

burner, Automatic no return diaphragm for separation from
combustion chamber.

• Nominal input, per module: max. 108 kW, min. 22 kW.
• Noise level at maximum output: lower than 49 dBA.
• Modules configuration possibilities:
•

Possible cascade installation of 2 or more Supermodu-
lex

• H

eating Operation: setting of instantaneous output

by a

main microprocessor, with a comparison parameters pre-
setting between the requested temperature (or calcula-
ted by the outer compensator) and the global flow

tem-

perature.

Logic of operation:
A) Output

sharing on as many modules as possible at min.

load (down to 22 kW) for the max. efficiency..
B) Automatic operation hour splitting-up system for each
module to guarantee the best homogeneous use.
C) D.H.W. production, via a storage tank loading pump or a
three way diverting valve, controlled by a priority sensor
through the E 8 heating controller.
D) Output check of each module for any calibration and/or
assistance by secret access code.

•

Possibility of controlling the output of each single module.

• Heating request control: temperature set point

andmodulation level.

• Monitoring of boiler and temperature status.
• Alarm control.
• Parameters setting.
• Relay for control of the operation of a pump at constant

flow rate.

• 0÷10V analogical output for control of a modulating pump.
• Emergency operation: it avoids C.H. system shut down

caused byan interruption in communication with the boiler
plant’s automation system: : (in case of remote control of
the complete boiler house):

• Input for “Constant setpoint”: 55°C, maximum output 50%.
• Alarm reset input.
• Aalarm relay signal.
•

Gas connecting pipes, flow

return water pipes, arranged

for any connection (by the opposite end).
