AND DIMENSIONS
2.1 - TECHNICAL FEATURES
•
MODULEX is a compact, gas fired, Low NO
x
, condensing
boiler .
•
made up by one sectional boiler body, suitable for a single
boiler working or directly as cascade
• Place even outside (IP X5D)
•
Low water content
•
Fast response to load variations
•
Flue terminal positionable on 3 sides
•
Manifold unified delivery and return (everseble in simple way
p.16)
•
Made up of two or more heating elements (2 to 7), cast alu-
minum / silicon / magnesium
•
Modulating premix burners total radiation
•
Each heating element without hydraulic interceptions
•
One gas supply pipe (reversible)
•
Modular power from 12 to 50 kW / element
TEMPERATURE CONTROL DEVICES:
• LOCAL NTC sensor (each heating element)

• Gas pressostat
• Smoke pressostat (
anti-obstruction )
•
The whole group has heat sensors NTC control global tem-
perature on the flow and return.
.
•
Integral insulation with synthetic wool hypoallergenic
•
Total premix burner, modulating burner with a “metal sponge” ,
ad irraggiamento. Premixing into the fan . Automatic diafra-
ghm backflow of separation from the combustion chamber.
•
Noise at maximum power of less than 49 dBA.
• Heating operation: determination of instantaneous power
microprocessor control, with preset parameters for compa-
rison between temperature (or calculated from the external
temperature regulation) and global temperature flow.
• Operation modes:
Ability to control power of the individual heating elements for
any calibration and / or assistance with access code confi-
dential.
Production of A.C.S. by NTC of priorities for control by
boiler feed pump or by three-way diverter valve controller
E8 included.
• Ability to control power of the individual heating elements
• Control of heat demand: set point temperature and level of
modulation.

• Monitoring of operating status and temperature.
• Reporting of alarms.
• Setting parameters.
• Relay control for the activation of a fixed speed pump
• Analog output 0 to 10V to control a modulating pump.
• Operation of emergency prevents the detention facility as a
result of the interruption of communication with the control
system or any remote control unit:
• With the possibility of temperature selection through emer
-
gency resistors supplied with “constant Setpoint: 70 ° C, max
50%.
• Alarm management
• Alarm reset input.
• Relay warning alarm.
• condensate collector tank with siphon stainless steel
• Panels complete with easily removable stainless steel panels
painted with fire adapted for outdoor installation
• condensate collection tank with drain trap and smoke chamber
in stainless steel.
• Built-in air vent
The application of heat can be generated by the Regolation / E8
operator or alternatively from BCM (boyler Cascade Manager)
The management logic provides the maximum number of
simultaneous operation of heating elements as possible in
order to maximize your productivity. As we provide high ex-
change surface as a function of output power. The items are
made to work so as to share equitably the operating time.
The hot water produced by the pump is pushed on the return
of the ring to the primary flow of the hydraulic separator. From
here a second pump (system - see the diagrams suggested) will
arrange for the distribution to various users. The return chilled
water plant is sucked by the pump on the return through the
hydraulic separator to resume the cycle via the generator.
