 Descrizione  Disegni e Misure  Libretti 

As compared to the power, weight and dimensions are extremely reduced.
These characteristics allow easily to install this boiler in any heating plant. Through a specific series of accessories it can be easily applied on both new and existing plants.
In case of a new heating plant, the reduced dimensions allow to save useful space.
In case of installation in existing heating plants in cellar and attic, the reduced dimensions facilitate transport and installation also in limited spaces.

Main Characteristics:

  • Input from 320 to 585 kW;
  • Class 5 NOx;
  • Energy efficiency (92/42/EEC directive);
  • High modulation range (from 18 to 100% of the power);
  • Efficiency: at 100% of the load with 80/60 °C  temperature = more than 97,5%; at 30% of the load with 30 °C on the return = 108%;
  • Aluminium, silicon and magnesium alloy primary low water content exchanger   (4 to 8 elements);
  • Total premix modulating burner with metal head;
  • Premix in combustion antechamber;
  • Automatic anti-return diaphragm for separation from the combustion chamber;
  • High level of silence at maximum power;
  • Possibility of cascade combination with a cascade control unit;
  • New electronic components to favour control of boiler parameters through telecontrol systems;
  • Control panel with alphanumeric display and program pushbuttons;
  • Thermoregulation with external probe (optional);
  • Domestic hot water production in combination with a remote calorifier controlled by the electronic components of the boiler.
