CASKADincreases output and efficiencyEfficiency (%)109108106104ALKON EFFICIENCYThe ALKON offers flexibleoperation and highoperating efficienciesWe have seen that the individualALKON boiler has an approved efficiencywhich, when the output reduces, increasesprogressively from 102 to 109% (incondensing mode).10210 15 20 25 30 35 40 45 5055 60 65 70Output (kW)This is possible because to the heatexchanger increases its efficiency, andflue temperature decreases, when theinput is reduced.Output sharing with 4 x 50kW modules in cascadeRequested output 200 kW50 kW 50 kW 50 kW 50 kWRequested output100 kW25 kW 25 kW 25 kW 25 kWIn order to increase the total operatingefficiency of the ALKON CASKAD,the E8 heating controller maintainsthe major number of ALKON unitsin the multiple boiler installation, firing atthe lowest possible rate (as shown in thebesides examples).Using this method the heating systemwill always operate at the maximumpossible efficiency, independentlyfrom the rate supplied.Total efficiencyη = 102Total efficiencyη = 106Always with the same operation principle,when the heating load slowly reduceitself, the output of each module will alsobe controlled and proportionally reduced.Requested output40 kW10 kW 10 kW 10 kW 10 kWRequested output30 kW10 kW 10 kW 10 kW OFFAs the minimum rate of each moduleis 10 kW, if the required load is inferiorto the total minimum output of the singleunits (n° units x 10 kW), only the ALKONboilers, needed to reach the requestedoutput at the maximum efficiency level,will be fired and the other units will beshut down.Total efficiencyη = 109Total efficiencyη = 109Moreover, in order to ensure an equaldaily rotation of each module, every24 hours each unit will be fired alternately,so as to ensure that each one operatesfor the same number of hours.
Accessories:neutralizing kitsOptionalacid condensateneutralizing kitThe condensate water produced duringcombustion reacts with NOx formingacid molecules (pH value = 4,5).It could become necessary to neutralizethese substances before their dischargein the drainage system water.In order to respect the ecosystem <strong>Unical</strong>proposes the NH condensate neutralizers.KIT NH 500– for boiler outputs upto 500 kW (code 00361551):the neutralization occurs accordingto the principal of the passage of acidiccondensate through the granularneutralizing material.The passage takes place from the bottomto the upper direction.FLOW RATEBOILER OUTPUTDELIVERY HEADFLUID TEMPERATURESTAGNATION POINT HEIGHTNEUTRALIZING SUBSTANCEDURATION OF NORMAL CONDENSATEl/hkW°CmmKIT NH 500UP TO 70UP TO 500-5-4090GENO® - Neutralit -Hz12 months (1500 operating hrs)KIT NH 1000up to140up to10004 m a 140 l/h5-4090GENO® - Neutralit -Hz12 months (1500 operating hrs)Kit NH 1000 – for boiler outputs upto 1000 kW (code 00361136): in the NH1000 system the condensate is convergedthrough a zone filled up by a granularneutralizing material, in which an integratedfilter layer can also be found.When evacuating this zone the neutralizedcondensate reaches a level controllerpump, also operating as an hoisting system,which pumps it towards the drain outlet.This system is able to treat up to 140 l/hof condensate, for boiler outputs up to1000 kW and it is approved by the Germanbody DVGW.CONDENSATE/AMBIENT WATER TEMPERATUREDIMENSIONS (lengthxwidthxheight)INLET/OUTLET CONNECTIONINLET/OUTLET HEIGHTHEIGHT TOO FULL OR 2° OUTLET TUBEELECTRICAL CONNECTIONABSORBED ELECTRICAL OUTPUTABSORBED ELECTRICAL SUPPLYPROTECTION GRADE°CmmmmWA5 - 60476x300x185DN 1550/90-----5 - 40640 x 400 x 270DN 20/DN 1050150230V/50Hz450,33IP 54CONDENSATE NEUTRALIZERSKIT NH 500 (boiler output up to 500 kW) code: 00361551KIT NH 1000 (boiler output up to 1000 kW) code: 00361136Neutralizer salts refill – Refill 8: code: 00361138Neutralizer salts refill – Refill 25: code: 00361139
