Thanks to the ACC Combustion system, each model self-adapts to different types of gas, without the need for "dedicated" codes for methane, LPG and propane air(*), or gas conversion kits EXCLUSIVE X , TECHNOLOGY FOR A GREEN LIFESTYLE From the R&D laboratories of Beretta comes EXCLUSIVE X, the new condensing boiler that marks a further step in the evolution of the EXCLUSIVE range, whose name has always characterized the top of the brand's wall-mounted offer. Combustion and electronics, which represent the heart and brain of the boiler, have been entirely redesigned to offer an even more performing and responsive product to the European objectives of environmental sustainability. EXCLUSIVE X is the ideal choice for those who are not satisfied and are looking for green solutions. EX CLUSIVE INNOVATION The new stainless steel exchanger, the innovative electronics with hybrid function integrated in the boiler, without external remote controls, and the ability to process mixtures of natural gas and hydrogen up to 20% give EXCLUSIVE X a highly technological profile, ensuring maximum energy saving, which translates into an economic advantage for the user . EXCLUSIVE PERFORMANCE EXCLUSIVE X represents the spearhead of the Beretta offer. Thanks to the new optimized plate heat exchanger , the range achieves sanitary performance at the top of the category in terms of efficiency, temperature stability and waiting times. The refined ACC electronic combustion system, which allows the quantity of fuel delivered to be continuously modulated, offers “best-in-class” efficiency and functionality in all circumstances, reducing harmful emissions to a minimum. EXCLUSIVE BERETTA The new range represents the synthesis of Beretta's advanced research, in continuity of style with the best tradition of the brand. Continuity that manifests itself both in the aesthetics of the product, which takes up the lines of the first Beretta boiler models, reinterpreting them in a modern key, and in the simplicity of use and installation flexibility, among the distinctive features of the brand, which have always been appreciated by the market A NEW HEART OF STEEL EXCLUSIVE X is equipped with a new primary exchanger in stainless steel , with a smooth tube with a large section, to ensure the best efficiency and cleanliness over time. Stainless steel, in addition to the high resistance to the corrosive action of acid condensate, prevents the internal formation of oxides and other electrochemical phenomena typical in installation on old systems. The geometry with a single wound coil (hydraulic circuit in series) guarantees constant flow in all sections of the exchanger and intrinsically prevents phenomena of clogging. Front access facilitates periodic maintenance and cleaning of the combustion chamber. COMBUSTION WITH ELECTRONIC INJECTION The ACC system, refined by Beretta for the EXCLUSIVE X , allows in all circumstances to offer functionality, efficiency and low emissions that are “first in class”. Using a sensor for detecting the flame ionization current, which allows the electronics to continuously modulate the quantity of fuel injected, the system keeps the air/gas mixture constant at optimal values ​​over the whole modulation range of the delivered power (constant CO2 value). Thanks to the sophisticated ACC system, combustion adjusts itself, thus eliminating the need for any calibration and allowing the boiler to operate with different gas compositions. Particular attention is paid to CO emissions, through a self-diagnosis that intervenes on the burner before the emission threshold allowed by the legislation is exceeded.

IMMERGAS VICTRIX 24 TT CONDENSING ERP COMPLETE WITH FUME EXHAUST KIT Technical features Immergas Victrix 24 TT condensing boiler Capacity: 24Kw Useful heating power kW: 20.5 DHW useful power kW: 23.6 Type: Instant Modulation range: 15 - 100% Hot water production (∆t 30 °C) l/min: 11.3 Electrical protection degree IPX: 5D Dimensions (HxWxD) mm: 748 x 440 x 280 VICTRIX TT The VICTRIX TT ErP range, intended for new installations and above all for the replacement of existing appliances, has been designed to comply with the new European Directives on the use of energy, increasingly oriented towards condensing technology to more easily reach the efficiency classes high in space heating and in the production of domestic hot water in homes. VICTRIX TT ErP, produced in the new highly automated lines of the company's historic headquarters in Brescello, incorporates the innovative condensing module which guarantees high flow rate and head on the heating circuit, low risk of clogging due to any impurities in the system and greater corrosion resistance thanks to the special alloy with which it is made. Reduced consumption thanks to the class A circulator and boiler power modulation up to 15%: ideal condition for mid-seasons or reduced loads. In addition to a very low environmental impact, the boiler features an advanced and easy-to-use user interface with adjustment knobs, selection buttons and LCD display for viewing operating temperatures, operating status and error codes. HIGH HYDRAULIC PERFORMANCE The condensing module has been designed to have large water passages which allow interesting flow rate and head performance even on old heating systems. This also means a low risk of clogging in the presence of impurities in the system water. It is made of a special Aluminium-Silicon-Magnesium alloy, a material which – together with the high thicknesses used – is particularly resistant to corrosion. The water circuit runs through the exchanger in an ascending manner, in counter-current with respect to the flame. The dense pinning allows you to increase the exchange surface ensuring excellent water yield. It is important to keep the pH of the heating system filling water between 6.5 and 8.5 with a hardness of 15°F (ref. UNI 8065 - DI 26/06/15). CLASS A CIRCULATOR The low-consumption modulating circulator guarantees considerable savings in electricity compared to a traditional circulator, it can be set in Auto or Fixed operating modes. WIDE MODULATION RANGE The electronic card reduces operating costs thanks to particularly high yields even with low energy absorption, as occurs for example in the mid-seasons. In fact, the wide range of modulation of the appliance (from 15% to 100% of the thermal power) determines high seasonal yields. LOW ELECTRICITY CONSUMPTION IN STAND-BY (LESS THAN 6 W) EVOLVED DESIGN The VICTRIX TT ErP range is designed to make the work of professionals easier. Immergas has invested significant resources in the industrialization of the parts of the appliance, making it particularly robust and has paid the utmost attention to details and finishes. VICTRIX TT ErP presents new technical features such as: • safety valve drain conveyed to the condensate drain • removable cover for direct access to the electrical connection compartment • cover casing for the water connections to better position the boiler in domestic spaces DIRECT ACCESSIBILITY TO THE ELECTRICAL CONNECTIONS COMPARTMENT In the lower part of the boiler there is a connection compartment accessible without the need to open the product but simply by removing the aesthetic cover, to house the electrical connections of the main devices that can be combined (for example CARV2, external probe, CRONO 7). ELECTRONIC AIR/GAS CONTROL The electronic gas valve allows air/gas control by means of a multifunction electrode placed inside the combustion chamber; the car electronic card adapts the combustion parameters in the event of variations in the density of the air or of the fuel. This allows VICTRIX TT ErP to be powered with any type of fuel (methane/LPG or propane air), by intervening only on the electronic board software even at a later time (for example at the first commissioning by the Authorized Assistance Centre). The boiler is therefore supplied with a single product code.

ATTENTION Natural gas, LPG, Propane air Ready through a simple configuration the boiler is able to operate on natural gas, LPG and propane air without the use of additional conversion kits. For info, contact the local authorized assistance center in advance NB: PRODUCT AVAILABLE ON ORDER Ferroli Bluehelix TOP RRT K 50 28C Methane or LPG condensing boiler Complete with Smoke Exhaust Kit cod. 0T3T2AWA - NEW Energy label specifications according to the European ErP directive Class A heating energy efficiency Sanitary energy efficiency profile XL Class A Characteristics of heating/DHW operation: Heating max / min heat input (Hs) kW 27.2 / 5.6 Heating power max / min heating (80/60°C) kW 24 / 4,9 Max DHW heat input (Hi) kW 28.5 Min DHW heat input (Hi) kW 5.0 Max / min DHW thermal power kW 28.0 / 5.0 NOx emission class (EN 15502-1) - 6 Max working pressure heating bar 3 Sanitary flow rate ∆t 30°C l/10min 161 Protection degree (IEC 60529) IP X5D Supply voltage V/Hz 230V / 50Hz BLUEHELIX TOP RRT K 50 BLUEHELIX TOP RRT K 50... THE EVOLUTION IS COMPLETE This range of generators is equipped with the tested primary heat exchanger in stainless steel and a 50-litre domestic hot water storage tank, also in stainless steel. Designed and built according to the new ErP directives for eco-compatible design and labelling, BLUEHELIX TOP RRT K 50 is at the top of its category. BLUEHELIX TOP RRT K 50 achieves one of the highest energy efficiency of space heating in the boiler category: ηs 94% (Class A ErP, scale from G to A++). Furthermore, when combined with the external probe and the Romeo remote timer control or the new Connect control, it reaches system energy class A+ (scale from G to A+++). TOP EFFICIENCY EVEN ON OLD SYSTEMS (REPLACEMENTS) The THERMOBALANCE™ heat exchanger of BLUEHELIX TOP RRT K 50 (fig. A) compared to the more classic and widespread steel exchanger (fig. B), abandoned in favor of the evolution towards the primary steel exchanger used in the models Bluehelix (2012 -> ). This geometry allows the heat exchanger of the THERMOBALANCE heating unit 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. INNOVATIVE THERMAL GROUP FERROLI THERMOBALANCE TM IN ITS 5 ELEMENTS Ferroli has oriented the design of the combustion cell and the exchanger of BLUEHELIX TOP RRT K 50 in order to maximize the functional advantages and the constructive sturdiness, as well as the simplicity of maintenance: the single-circuit design means that any air bubbles in the system do not remain trapped in the exchanger, and facilitates cleaning with chemical washing as much as possible, unlike spiral exchangers with double parallel circuit (more common) in which if only one of the circuits is blocked, chemical washing is much more laborious. THE ENGINE The tube that makes up the BLUEHELIX TOP RRT K 50 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. TOP QUIETNESS The particularly careful design of BLUEHELIX TOP RRT K 50 has made it possible to achieve significant values ​​in terms of silence and acoustic comfort, so much so that it could almost be difficult to distinguish the background noise of a home from the noise produced by the boiler during normal operation. . Even the boiler on/off transients have been optimized as a function of acoustic comfort, so that the customer will no longer have the hassle of understanding whether the boiler is on or off from its noise as with older generations of boilers. The planning also took care of the design, creating a precious mantle in 3 removable pieces, which descends to cover the pipe connections. THE BOILER CONTROL The control and management electronics allow the user to customize the operation of the appliance in order to manage the environmental comfort according to one's needs. The key control panel and the simple LCD display make the programming operations for the production of hot water, both for domestic hot water and for heating, extremely easy and intuitive. Thanks to the remote connection via bus, this can also be done directly from the remote control. The card is protected by an easily accessible fuse thanks to the dedicated flap and the electrical connections benefit from a robust and large box, with easily accessible connectors and numerous cable ties. The boiler is also set up to connect a second room thermostat to the dedicated terminals to manage multi-zone mixing systems. 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). EASY 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 "Thermobalance"TM thermal group allows maintenance to be carried out with maximum precision and speed. Some examples: Internal accessibility is favored by the 3-piece mantle with removable side panels. The electrical box of the electronic board can be easily rotated on the chassis leaving free access to the internal parts. The fan, offset from the burner and placed underneath, must not be disassembled to access the steel burner-exchanger unit. The burner door is totally self-air-cooled and therefore does not require an insulating panel, avoiding the risk that this could be damaged or broken during disassembly for cleaning. The burner can be disassembled by loosening just 3 bolts leaving free access to the stainless steel exchanger. 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 SIMPLIFIED REPLACEMENT The new boiler can also be installed with 50mm diameter ducting outlets. Particularly important in the replacement market in the frequent case of collective flues that require "heavy" ducting where it is necessary to have a high fume expulsion capacity even with reduced diameters. STOP AND GO FUNCTION With the use of sanitary taps with mixing, 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 TOP RRT K 50 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 SUN EASY FUNCTION BLUEHELIX TOP RRT K 50 has been designed to be easily inserted into systems built 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. Through a sensor placed on the DHW circuit, it continuously monitors the temperature of the water preheated by the solar panels, foreseeing the ignition of the burner only if the latter falls below the level necessary to guarantee optimal comfort for the user 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. Achieving maximum comfort certified 3 stars (EN 13203). The efficiency and the load profiles according to the ErP directive are at the top of the category: mod. 28 / A - XL | mod. 34/A - XXL MODULATION RANGE The new control electronics allow to reach high modulation fields which can reach up to 1:12 for the 34 K 50 model (1:10 for the 28 K 50). In this way BLUEHELIX TOP RRT K 50 is able to adapt to the effective power required by the system with extreme ease and efficiency, avoiding annoying on/off type operations which increase operating costs and reduce the average life of the product.
