Aesthetically it looks like the previous one but its technology is now completely different. The Ciao LX CAI is the entry-level model for approaching Beretta boiler technology; the CAI model has an open chamber and natural draft. The adjectives that identify it are: high quality standard, sturdiness, reliability and economy in purchasing and running. The innovative Double Exchanger is very compact and is of the plate type with the possibility of preheating . It also uses a low consumption Synchronous Circulator (EEI=0.20) with anti-block cycle system and 3-way valve; it is equipped with a smoke control thermostat and by-pass on the heating circuit. Beretta Ciao has a simple, modern and elegant line; the front panel, the real brain of the boiler, is equipped with many functions. Ciao LX CAI is designed to be installed outdoors in partially protected places, thanks to the dedicated accessories and board antifreeze protection down to 0 °C. In colder temperatures it is possible to extend the protection down to -10 °C using the special antifreeze heater kit together with the siphon antifreeze heater kit (optional to be requested separately from the Beretta Technical Assistance Centre). A convenient liquid crystal digital display for viewing the temperature and diagnostic codes, the on/off/summer/winter/reset/heating temperature/ Amico Climate System selector, the domestic hot water temperature selector/pre-heating activation, the Hydrometer. The wall water fittings, the sanitary taps and the gas tap are not included in the package. GUARANTEED SAVINGS AND HIGH COMFORT Gas consumption is always very low . This new version complies with the new standards on combustion gas emissions (NOx 6) e the ErP Directive 2015 ; the boiler benefits from Energy Classes C in Heating and B in Sanitary . It all starts with savings, starting from the purchase price up to consumption management. Maximum comfort with minimum cost.

Nel suo DNA ha la piattaforma tecnologica KON, integrata all’“accumulo” da 60 litri superfast, in acciaio INOX AISI 316 L. È concepita per garantire docce confortevoli con erogazione a temperatura costante e per lungo tempo, senza risentire di “variazioni” causate dall’inserimento di altre utenze. Con l’accumulo a 70°C si dispone di ben 50 litri di acqua ad alta temperatura, miscelabili con acqua fredda, che forniscono oltre 195 litri nei primi 10 minuti con Δt 25K. L’erogazione dopo la scarica del bollitore prosegue per mantenersi a 45°C costanti nel tempo. L’utente potrà scegliere ovviamente la temperatura di consegna mediante il comando a bordo del pannello. La preparazione del bollitore avviene in circa 10 minuti da freddo e la ricarica, a partire da 45°C, in meno di 6 minuti. Il sistema di priorità sanitaria si basa sul pluritestato complesso con valvola a 3 vie elettrica. Un binomio hardware e software effi cientissimo, che consente il funzionamento in alta e bassa temperatura a priorità differenziate, abbinata all’eccellente gruppo scambiatore-condensatore premix, fornisce velocità di messa a regime dell’impianto di riscaldamento ed elevatissimo risparmio. Particolare attenzione è stata posta inoltre, alla riduzione delle emissioni sonore nonché all’isolamento del bollitore per evitare inutili dispersioni. KON B, la protagonista firmata Unical. Risparmio con lo scambiatore primario esclusivo in Al/Si/MgKON B impiega, come tutti i prodotti di ”Scuola Unical” un originale scambiatore primario. È realizzato in una speciale lega di Alluminio/Silicio/Magnesio che ne assicura effi cienza e resistenza tanto che è garantito da Unical ben 5 anni. Grazie alla confi gurazione di scambio termico interno si raggiungono rendimenti fi no al 108,2% (ex dir. 92/42) in regime di condensazione, che signifi cano per l’utente grande risparmio economico e ridottissimo impatto ambientale, per il miglior sfruttamento del combustibile.Ampia modulazione di potenza Questa dote permette di determinare, grazie al termostato e ai sensori di bordo, la giusta potenza istantanea necessaria, riducendo i fenomeni di on-off responsabili degli elevati consumi. L’omologazione in banda di potenza (Range Rated) dà l’opportunità di fi ssare la potenza erogata adeguandola all’esigenza dell’impianto. Il sistema “ANTIFAST” riduce ulteriormente i cicli di accensione e spegnimento ottimizzando rese e costi. Si tratta di un ritardatore elettronico di accensione che interviene dopo lo spegnimento della caldaia per raggiunta temperatura. Vantaggi: Rapidità di messa a regime all’accensione. Riduzione dei cicli on-off con diminuzione dei consumi e dell’usura dei componenti. Bruciatore premix modulante A controllo elettropneumatico e a rapporto di combustione costante, il bruciatore tipo “Flat” assicura lunga durata grazie alle basse sollecitazioni termiche e meccaniche ed all’inalterabilità fi sica del tessuto in fi bra FeCrAlloy, oltre ad una propagazione ideale del calore per irraggiamento grazie alla sua struttura capace di sviluppare una fi amma particolarmente morbida e luminosa. Lo sblocco “Quick release” sia della piastra superiore che del fondo dello scambiatore, permette la rimozione completa del sistema di combustione assieme all’ampiamente collaudato ed aggiornato complesso di elettronica e sistema di premiscelazione. L’elettrovalvola gas pneumatica ed il ventilatore, entrambi modulanti, si distinguono per il limitato ingombro. Vantaggi: compattezza e ridotta emissione acustica ampio range di modulazione 1:6,3 assoluta sicurezza d’esercizio per l’assenza di turbolenze La valvola è progettata per compensare le fluttuazioni di pressione del gas presenti nelle reti nonché stabilizzare la pressione di alimentazione indipendentemente dalla pressione di aspirazione generata dal ventilatore del premix. Facilmente regolabile, assicura una accurata miscela di combustione aria/gas (Low NOx) per garantire elevati tenori di CO2 e favorire la condensazione. Circolatore modulante al alta efficienza con disareatore Rappresenta lo stato dell’arte nello standard dell’alta effi cienza. In linea con la direttiva ErP del 2015, con meno di 1W di consumo in stand-by e soli 45W in funzionamento al massimo, grazie all’ampia capacità di modulazione, in base alla richiesta del termostato ambiente e alle temperature rilevate dai sensori posti in mandata/ritorno, dosa automaticamente la potenza della caldaia alle esigenze dell’impianto. Nella preparazione del bollitore di acqua sanitaria concorre positivamente a velocizzare i tempi e a ridurre gli on/off del bruciatore. Particolarmente silenzioso e compatto, si integra perfettamente con la valvola di sicurezza, il by-pass regolabile ed il rubinetto di scarico. Dentro al bollitore Capacità di 60 litri di accumulo, completamente flangiato, facilmente ispezionabile e coibentato in polistirolo autoestinguente. Acciaio INOX AISI 316 L Disposizione del serpentino acqua-acqua in 2 spirali concentriche estraibili disposte nella parte inferiore del bollitore. Si ottiene così il massimo scambio termico con l’acqua fredda in ingresso, che viene iniettata da uno speciale rompi flusso il quale riduce la turbolenza nella zona superiore ove avviene il prelievo di acqua calda Lunghezza del serpentino primario: 13 metri Superfi cie di scambio: 0,85 m2 Tempo di caricamento da 12 a 74°C: 10 minuti circa Rubinetto di svuotamento Efficienza energetica di riscaldamento dell’acqua ηwh pari al 68,1% secondo la dir. Erp, che ne fa un bollitore in grado di sostenere impegnativi ed intensivi prelievi anche protratti nel tempo. L’anodo di magnesio preserva dalle correnti parassite l’integrità del bollitore e ne conferma la garanzia di 5 anni. Acqua sana grazie all’antilegionella: l’utilissimo programma elettronico automatico prevede, ogni 186 ore, un ciclo ad alta temperatura (70°) che “sterilizza” il bollitore impedendo qualsiasi proliferazione batterica. Garanzia prodotto : La garanzia su questo articolo è 24 mesi dalla data dell'acquisto.
