2.1 - TECHNICAL FEATURES
• MODULEX is a compact, gas fired, Low NOx, 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 (BMM), which manages completely
the temperatures from the point of view, both operational
and safety. This version is suitable for only central heating
CAUTION: These devices are not suitable for the
production of water for human consumption
• Efficiency at full load with temperature 30/50°C = 101,1%.
At part load (30% of the nominal) with 30°C return tempe-
rature = 107,2%.
• Efficiency Class:
• Each module, is composed of a combustion chamber, me-
tallic fiber pre-mix burner, modulating fan, gas valve, igni-
tion electrode, 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.
• Total premix burner, modulating burner with a radiant “me-
tal sponge” (NIT). Premix antechamber combustion. Auto-
matic backflow valve, preventing gas in the place of instal-
lation.
• 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 50 dBA.
• Modules configuration possibilities:
•Possible cascade installation of 2 or more Modulex
•Heating 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.
2TECHNICAL FEATURES
AND DIMENSIONS
• 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”: 82°C, maximum output 50%.
•
Alarm reset input.
•
Alarm relay signal.
• Gas connecting pipes, flow/return water pipes, arranged
for any connection (by the opposite end).
• Integral easily removable panel set (painted steel panels).
• Smoke exhaust pipe, adjustable on the right, the left and
behind the heating system.
• Condensate collecting tank equipped with drain siphon
and stainless steel smoke chamber.
• Built-in air vent.
• Weights and dimensions are limited (see table at par. 1.2)
•Instrument panels secreted (POP-UP)
