ENERGY TOPCondensing boiler solutions1

ENERGY TOP> > > Heating division> ENERGY TOP RANGEA wide array of flexible solutions both for centralisedresidential application and big commercial plantsThe increasing need for families to be able to manage their central heating systemfreely and independently led to the expansion of independent systems, gainingground over the traditional centralised approach to heating. Independent systemshave been and continue to be preferred by users, mainly due to:- independent management- costs exactly corresponding to own consumption;- less possibility of controversies between residents.Nonetheless, centralised systems, albeit less appreciated by users, have beenrecently reappraised thanks to some undeniable qualities : less overall capacityinstalled; less environmental impact due to the use of just one flue or stack, andseparate installation of the generator in a boiler room.The development of centralised systems with independent billing, using so-calledsubmeter, combine all the advantages of independent and centralised systemsmentioned above. For this reason, the new series of ENERGY TOP modularheat generators together with submeter DADO (not described in this catalogue)represent a modern and complete solution to the latest needs, which require abalance between centralised production of heat and independent and individualmanagement of consumption.Both in the residential and the commercial field, wide output modulation range ofEnergy Top, additionally enhanced in modular installation, together with its low hydraulicpressure drop, allows design and carrying out of flexible systems with extremely compactdimensions, fully in line with the latest heating technology design criteria.PRODUCT IN BRIEFPROTECTEDEXTERNALREMOTEMODULARCLIMATICCLASS 5NOX-5 .

ENERGY TOP> > > Heating division> THE HEARTHEATING UNITThe HEART of ENERGY TOP is an innovative heating unitthat ensures the product excellent characteristics in terms ofefficiency and flexible modulation. The new total premixed air-gascombustion unit with variable speed fan, pneumatic gas valve andcylindrical metal fibre burner allows a range of modulation that,depending on the model, can extend from 11 to 100% of ratedoutput, with efficiency exceeding 107%. Heat exchange takesplace in the spiral corrugated pipe exchanger, which features lowpressure drop. Despite the high heat exchange surface, it isparticularly sturdy and compact.The quality of the materials used ensures the exchanger a highlevel of resistance to corrosion and thermal dilations, supportinga max ΔT of 40°C. The very low polluting emissions - NOx andCO - as well as minimising the environmental impact of theseheat generators (class 5 according to EN 297/A5), also let theheat exchanger remaining clean over time, reducing to theminimum maintenance intervention. Ignition is electronic, withflame control by ionisation.The heating units have been designed with two different heatinput ratings: 75 and 116 kW, and based on the total output, thevarious models of ENERGY TOP can house one or two units of 75or 116 kW each, always inside a unique cabinet structure.The models with two heating units are also managed by the sameelectronic controller.100%50%30%22%11%ENERGY TOP 80> MODULATION RANGEENERGY TOP 125ENERGY TOP 160ENERGY TOP 250PREMIX BURNERPremixed air-gas, metal fibre burner,with variable speed fan.EXCHANGERConsisting in a spiral corrugated pipeENERGY TOP Bwith two heating units3

With just a simpleconnection (two wires) between the control boards of the boilers in the cascade, the entire system acts as a single virtual boiler. The safetycircuit reduces boiler lockout and system shutdown, automatically attempting to ignite the module three times in the event of temporaryshutdown (natural gas versions). If the shutdown occurs repeatedly, the system goes into permanent lockout mode, for safety reasons.Control board features a series of input and output signals, both analogue and digital (on/off), in order to control or adjust the operation ofthe single boiler or the entire cascade system also via a remote connection. Below are some examples:FAULT SIGNALActive in case of boiler’s fault messageBURNER ON SIGNALActive when at least one heating unit is onRESET SIGNALUsed to reset “temporary” faultsCombined management of the signals allowsthe operating status of the heat generatorto be checked and set via a remote connection°C/%P10 Volt0-10 VOLT INPUT SIGNALAllows the boiler (or cascade of boilers)to be controlled via a remote connection,in system outlet temperature or outputpercentage mode.ELECTRONIC INSTALLATIONSUPERVISOR4
