INKAL:the hidden heating

INKAL:the boiler thatdoesn’t need spaceINKAL solves the boiler positioning problemwith the minimum space using and themaximum safety. Its small box in galvanizedsteel allows high engineering freedom andmake easier the installation thank to theoriginal fitting system. For the INKAL boxinstallation are just needed:

• Depth: 215 mm• Height: 1190 mm• Width: 590 mm

INKAL is available in the combiinstantaneous version, with Domestic HotWater production. Only in sealed room,forced draught version, can be used withnatural gas or LPG; a double electronicignition system with electrodes makes ofINKAL a safe choice in every weathercondition.

Equipped of simple controls and easyadjustments, it’s studied in order to givevery high reliability in the most criticaloperation conditions.

INKAL has obtained the approval with theInsulation Protection degree IP X5D, withvery high waterproofing to direct waterthrows. It can operates also with extremetemperatures up to -15°C and +60°C.

A record

INKAL: the new reference pointfor the outdoor boilersIdeal, both for new installations and substitutions,INKAL allows to exploit at the best the space insidethe house. For no other built in boilers is necessarya so reduced wall niche:

• Box depth: 215 mm• Height: 1190 mm• Width: 590 mm

The compact galvanized steel box, to be built in,is already equipped of pre-cuttings necessary forthe passage in all the directions of hydraulicconnections, smoke duct, electric wiring and gassupply.

INKAL: practically is a boiler for“space saving”The minimum galvanized steel box dimension, itsextraordinary waterproofing, the minimum detailsattention, the operation silentness make a preciseconcept and extablish the future standard for“outdoor” boilers, placing it at the top for functionalityand beauty. Naturally, the front part that can bepainted on the same wall tonality allows to thisboiler to remain a protagonist behind the wings,by adding technologic and aesthetic value to thehouse for which is provided for.

Integrated aesthetic

Technology of valueWith its compact and harmonious look,INKAL adds value to heating systemwhere it’s installed.

The possibility to realize different smokeand hydraulic configurations, like the 2zones management, solves and makeseasier the installer work.

The perfect integration with the supportwall thank to its very reduced depth,makes of INKAL a valid aesthetic solution,with total respect of architectonic contest.

The user will live its own home in totalquietness, feeling himself psychologicallyfar from dangers from fire and gas.

3 solutions for “controlling” INKAL

system with 16 anomalies shown withnumeric codes is available, for a quickertechnical intervention.

• TM 2000offers the SIM-CRONO features, but thanksto its wide display gives the informationin English and in other languages onadjusting, parameters setting anddiagnostics.

SIM-PLEX SIM-CRONO TM 2000

Control panelFor easy use, constitutes asingle vertical unit, that is apart of box containing theelectronics.

Unical target is to simplify the life of allowners of INKAL by introducing a newcollection of technological remote controls,in order to control the boiler with a fewoperations, everywhere it’s placed.

Always more refined models• SIM-PLEXlike to have the boiler controls: DomesticHot Water temperature adjusting, CentralHeating temperature adjusting, boiler reset,water filling, lock-out led, leak of waterled.

• SIM-CRONOadds to the SIM-PLEX functions a weeklychronothermostat for the simplified settingof boiler ignition and switching off periodsand for the room temperature controlthanks to the integrated modulatingadjusting. This logic allows to reduce,modulating, the boiler output and thenconsumptions, by the simultaneouscomparison of two data: the boilertemperature and the output required forthe room warming. In addition, a diagnostic

Vanguard components

Components accurancyFor INKAL the F.M.P. technology isused (Few Moving Parts), to guaranteehigh reliability. The engineeringstudies have obtained a precious target:the extraordinary dimensions.The depth of only 21 cm set INKALat the top of the flat boilers, thank to:

• Monothermic primary heat exchanger with special threated connections anda depth of only 145 mm: it guaranteesall the necessary capacity and the idealefficiency both at 24 and at 8,9 kW (max.and min).

• DHW 16 plates inox AISI 316 L heat exchanger It’s mounted a sanitary heat exchangerwith 16 plates in stainless steel AISI 316L, in order to rationally use the availablespace. It’s oversized of 25% incomparison to the boiler output. Thischoice gives an higher exchange surfaceso, with the same water temperatureand needed quantities, it’s possible tolet the boiler work with lowertemperatures obtaining:

• Reduction of limestone depositphenomena

• More instantaneous Domestic Hot Waterwarming

• Constant water temperature during thedrawings

• DHW production of 13,4 l/min with ∆t 25°K.

• Motorized diverting valve Of new conception, result of Unicaltechnologic study, it’s part of a brasshydraulic group very compact and,thanks to the powerful electric motor,allows quickly and safely to divert thehot water produced by the primary heatexchange to the sanitary heat exchangeror in loop to the heating circuit,

optimizing the operation in temperaturemodulation with the special modulatingremote controls.

• The automatic by-pass allows to optimize the water circulationinto the boiler, avoiding in this wayoverheatings.

Automatic or manualwater filling…The manual filling and drain valves allowrapid interventions, and the connectionsand interventions are simplified thanks tovertically sliding control panel.For more exigent demands, the automaticwater filling will do all itself: in case of“low pressure” signal, the boiler software,that continuously controls the systempressure, will provide to fill in the water.If this filling up will be not enough, thealarm led will inform the user of a possibleheating system or boiler water leakage.

The combustion chamber is frontallyaccessible, so as the burner, the heatexchanger and the fan.

The combustion adjusting are also reallyrapid thanks to the provided forchimneysweeper function.

The electronic management bymicroprocessor controls constantly all

The UNICAL components technology isthe result of an accurate analysis realizedmostly on three ways:

• qualitativeto guarantee in every weather conditionoperation reliability and high performances;

• dimensionalassuring a very reduced total depth thatallows the installation everywhere and inharmoniously;

An “elevated service content” to savetime and money is what INKAL offersto the installers and the user.The installation is quick withoutdoubts. A metallic wall template isdelivered for the rapid positioning.Smoke ducts for the differentconfigurations both outdoor (B23) orindoor (C) and the complete availablecatalogue, with the high fan pressurehead, will allow to solve everysituation.

INKAL allows the M 3000 installation,an electro-hydraulic device for thesimultaneous management of hightemperature circuits (radiators) andlow temperature installations (floorheating systems).
