More beautiful than "BEFORE" The new range of generators is equipped with the tested heat exchanger in stainless steel . Designed and built according to the new ErP directives for eco-compatible design and labelling, BLUEHELIX ALPHA is at the top of its category. TOP EFFICIENCY EVEN ON OLD SYSTEMS (REPLACEMENTS) mod. 24 C COMBINED (14 l/min at ∆t 25°C) The BLUEHELIX ALPHA thermal group exchanger (fig. A) compared with the more classic and widespread steel exchanger. This geometry allows the exchanger to operate almost at maximum design efficiency even in conditions of partial blockage, while with the same amount of deposits and sediments (e.g. due to installation on old systems) the exchanger in fig. B tends to block up much faster in the part in contact with the flame due to the reduced passage area of ​​the fluid, in which a real barrier of deposits * is formed which hinder the heat exchange and reduce the efficiency beyond below the nominal values BLUEHELIX ALPHA FROM THE INSIDE EXCHANGER High flow single circuit stainless steel exchanger, resistant to clogging and easy to clean STEEL FRAME Made with high precision automated processes EXPANSION TANK 8 liter expansion tank placed on the side ELECTRIC PANEL FAN Offset fan, to facilitate maintenance of the primary exchanger without disassembly DOMESTIC HOT WATER EXCHANGER In stainless steel, with copper brazing CIRCULATOR High efficiency, for heating and exchange with the DHW circuit SEALED CHAMBER Removable steel panel to protect the combustion chamber with the function of a sealed chamber ELECTRICAL PANEL Large removable electrical panel to protect against water damage that may occur during normal maintenance. Easy access to electrical connectors. THE ENGINE The tube that makes up the BLUEHELIX ALPHA exchanger is made of stainless steel, a material that allows for the creation of an extremely smooth surface, therefore less susceptible to encrusting agents and deposits. THE BOILER CONTROL The control box of BLUEHELIX ALPHA consists of an easy to use interface with backlit display. Using the buttons, it is possible to easily adjust the heating flow temperature, the domestic hot water setpoint, switch the generator on/off or activate the comfort function, monitoring the status of the boiler. The control panel is completed by a traditional pressure gauge which can check the system pressure at any time. MC2 The electronics control the flame ionization current in order to ensure optimal combustion as the air density or gas quality varies. The relationship between the air/gas ratio (λ) and the flame ionization signal is used to control the air-gas ratio itself and therefore the combustion. MC2 : Multi Combustion Control, the new combustion system with patented Gas-adaptive technology improves the adaptability of use as the conditions of the gas network vary (e.g. fluctuations or reduced pressures). MGR Methane, LPG, Propane Ready Air The electronics control the flame ionization current in order to ensure optimal combustion as the air density or gas quality varies. The relationship between the air/gas ratio (λ) and the flame ionization signal is used to control the air-gas ratio itself and therefore the combustion. MC2 : Multi Combustion Control, the new combustion system with patented Gas-adaptive technology improves the adaptability of use as the conditions of the gas network vary (e.g. fluctuations or reduced pressures). Thanks to the new electronics supplied, the gas change operation is extremely simple. The MC2 combustion control performs constant monitoring of the quality of the combustion and by simply modifying a parameter on the electronic card (operation to be carried out only by qualified personnel) it is possible to operate the boiler on Natural Gas or LPG or Propane Air. It is therefore not necessary to purchase additional accessory kits. CONNECT New wireless remote control available as an accessory for home comfort management also from a smartphone using the connect app (iOS and Android). Maximizes room comfort with delivery temperature modulation through the Room Climatic Compensation (CCA) and External Climatic Compensation (CCE) functions via the external temperature detectable directly from the internet (or from an optional external probe). It improves the average seasonal efficiency in space heating by +4%. EASY MAINTENANCE Problem-free maintenance At the time of the first maintenance, the technician can appreciate the care with which every detail has been designed to facilitate his work. Thanks to the maximum accessibility of the main components, the BLUEHELIX ALPHA thermal group allows maintenance to be carried out with maximum precision and speed. Some examples: - The electrical box of the electronic card can be easily extracted from the chassis leaving free access to the internal parts. - Easy access to the burner unit by removing 4 screws and the quick coupling (clip) of the fan. - The exchanger with extra-large passages is designed to challenge the hardest waters and is easy to clean thanks to the non-collectorised single-pipe circuit. - The domestic hot water inlet filter can be extracted very easily directly from the inside without having to remove the boiler hydraulic connections. - Any disassembly and replacement of the plate heat exchanger takes place simply by removing the two Allen bolts accessible from the front SUN EASY FUNCTION BLUEHELIX ALPHA has been designed to be easily inserted into systems made with the latest technologies. The SUN EASY system makes use of electronics that simplify the combination with solar panels with both natural and forced circulation. By means of a sensor located on the DHW circuit, it continuously controls the temperature of the water preheated by the solar panels, foreseeing the ignition of the burner only if the latter drops below the level necessary to guarantee optimal comfort for the user. STOP AND GO FUNCTION With the use of sanitary mixing taps, short or very short dispensing for quick rinses involves the start of the boiler ignition procedure which usually ends immediately. The continuation of these "false starts" can, in the long run, compromise the average life of the product. For this reason BLUEHELIX ALPHA provides an electronic parameter through which it is possible to delay burner ignition (Stop and Go) by activating it only in the face of actual withdrawals of domestic hot water. OUTDOOR INSTALLATION - ANTIFREEZE FUNCTION To make the most of the available space, the new BLUEHELIX ALPHA 24 - 28 C boiler can be installed recessed into the wall thanks to the special kit; for more critical installations, in completely uncovered places not protected from atmospheric agents, the "painted cabinet" kit is also available. In the event that the temperature in the boiler drops to 5°C, the burner automatically lights up and the circulator is activated in order to protect the appliance from damage caused by frost. This function is active with the boiler powered by the gas circuit and under electrical voltage. SANITARY ECO-COMFORT FUNCTION In ECO operation, the production of domestic hot water takes place according to traditional standards, allowing for energy savings during periods of non-use. In COMFORT mode, thanks to the particular heat exchanger temperature maintenance system, the delivery of domestic hot water becomes even faster and more comfortable. The efficiency and the load profiles according to the ErP directive are at the top of the category: mod. 24 C / A - XL. Product Warranty All products for sale on our site are new and packed.

The acronym ErP, an acronym for "Energy related Products", identifies Directive 2009/125/EC aimed at reducing the energy consumption of products through eco-compatible design. Starting from 26 September 2015, the date of its effective entry into force in the European Union, it will mark an epochal turning point for heating products and the production of domestic hot water. On that date, other regulations issued at the same time for the energy labeling of products to supplement the corresponding Directive 2010/30/EU will also become effective. The regulation provides that all products intended for heating and for the production of domestic hot water with a nominal thermal power lower than or equal to 70 kW can only be placed on the market with an energy label that highlights the efficiency class. Different energy efficiency labels have been provided based on the different types of appliances/technologies, but all have the same graduated color scale that identifies the various levels of efficiency at a glance. The purpose of the labels is to give the consumer the possibility of easily identifying the level of efficiency of a product and to be able to make a homogeneous comparison between products that use different technologies. For products whose transformation efficiency is influenced by external conditions, such as heat pumps, the efficiency data is reported by climatic bands. In addition to the product labels, the European regulation has provided for the creation of a system label in case systems are created with different appliances, components and related controls. This second type of labeling, thanks to the virtuous synergy between the different elements, will make it possible to create systems capable of reaching levels of efficiency even higher than those of the individual devices. Also starting from the same date, new seasonal efficiency limits will be triggered for products intended for heating and combined. These for products with a nominal thermal power equal to or less than 400kW, will prevent less efficient products from being placed on the market. The obligation to comply with minimum heat loss limits will also apply to DHW tanks. For primary water tanks, these will be subject to compliance with an energy classification based on heat dispersion. For sanitary accumulations, up to 500 liters there will be a labeling obligation, from 500 to 2000 liters will be bound to compliance with the energy classification. For heat pumps for heating and mixed appliances, in addition to the seasonal efficiency limits, there will be specific noise emission limits for power sizes. Even water heaters, whether gas, heat pump or solar, in order to be placed on the market, in addition to energy labelling, will have to comply with a series of requirements in terms of efficiency. Beretta's commitment is concrete and is directed towards an increasingly eco-sustainable future. This is why Beretta is already ErP-Ready today with solutions for any installation and comfort requirement linked to autonomous residential and centralized systems. A complete and constantly evolving catalog with many ErP-Ready proposals in the case of mere replacement, energy redevelopment, renovation or new construction.

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.
