The new range of generators features the proven stainless steel exchanger. Designed and built according to the new ErP directives for eco-design and abelling, BLUEHELIX ALPHA is at the top of its class.

Product advantages:

• Boiler with primary exchanger made of stainless steel mono circuit without joints and/or welds, maintains high efficiency even on old systems
• MC2: Multi Combustion Control, new combustion system with patented gas-adaptive technology of industrial derivation for better adaptability of use to varying conditions of the gas network (e.g. fluctuations or reduced pressures)
• M.G.R: Methane, LPG, Propane Air Ready by means of a simple configuration the boiler is able to operate on methane, LPG and propane air without the use of additional conversion kits
• Instant production of domestic hot water with dedicated plate heat exchanger
• User interface with display and multifunction keys for adjustment and setting of parameters
• Standard by-pass
• Predisposition for solar systems: prearranged for the production of domestic hot water combined with solar panel systems
• Intubation on flues: particularly suitable for operation in flues that require heavy intubation thanks to the approval for operation with 50 mm diameter flue gas discharge
• Minimum polluting emissions (class 6 according to EN 15502-1)
• Sliding temperature operation through optional external probe
• Low consumption modulating heating circulator (ErP Ready - Class A)
• User interface with display and multifunction keys for adjustment and parameter setting
• Digital flame control with three re-ignition attempts in case of operation block due to lack of flame detection (methane mod.)
• Place of installation: also for outdoor use in a partially protected place down to -5°C as standard and down to -15°C with the optional antifreeze heater kit
• Casing can be disassembled into three pieces for easier maintenance or inspection
• F.P.S.: Smoke Protection System. With the use of the optional flue accessory (041106X0 - Exhaust gas clapet valve kit), which can be installed on the outside of the boiler, it is possible to easily connect to pressurised collective flue systems (e.g. in renovations), in accordance with UNI 7129.
  
  

SUN EASY FUNCTION

• BLUEHELIX ALPHA has been designed to be easily installed in systems made with the latest technologies. The SUN EASY system uses electronics that simplify the combination with solar panels with both natural and forced circulation. By means of a sensor located on the sanitary circuit, it continuously controls the temperature of the water pre-heated by the solar panels, foreseeing the ignition of the burner only if the latter drops below the level necessary to guarantee optimal comfort to the user.
  
  

STOP AND GO FUNCTION

• With the use of mixing sanitary taps, short or very short deliveries for quick rinses start the boiler ignition procedure, which usually ends immediately. The persistence of these "false starts" can, in the long run, compromise the average life of the product. For this reason BLUEHELIX ALPHA provides a parameter of the electronics through which it is possible to delay the ignition of the burner (Stop and Go) activating it only when there is a real withdrawal of sanitary hot water.
  
  

SANITARY ECO-COMFORT FUNCTION

• In ECO mode the production of domestic hot water takes place according to traditional standards, allowing energy savings during periods of non-use. In COMFORT operation, thanks to the special system of maintaining the temperature of the heat exchanger, the supply of domestic hot water becomes even faster and more comfortable. The efficiency and load profiles according to the ErP directive are at the top of the category: mod. 24 C / A - XL.
