TECHNICAL FEATURES

AND DIMENSIONS

2.1 - TECHNICAL FEATURES

• MODULEX is a compact, gas ﬁred, Low NO

, 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)

• Limitthermostatroom(eachheatingelement)

• ﬂow NTC sensor (General)

• NTC sensor return (General)

• Safety thermostat approved (Order and install on ISPESL

device see page 18)

• FlowsensorBCM

Other safety devices (RACCOLTA R) see 3.6 pag. 18

Control panel (POP-UP) includes:

• Airpressurefans

• Condensatelevelsensor

• 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ow.

• 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.

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ow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.
