Boiler Pellets Fuzzy Logic 2, Kostrzewa

Application and advantages of the boiler Automatic PELLETS FUZZY LOGIC 2 boiler is intended for combustion of solid fuels such like pellets, pea coal, cereals, wood.
It can be used to heat single or multi-family houses, smaller resorts, workshops, schools, offices, etc.


 

Boiler Pellets Fuzzy Logic 2, KostrzewaAdvantages of Pellets Fuzzy Logic boiler

  • Modern design of steel heat exchanger, allowing the achievement of efficiency above 90%;
  • Possible combustion of four types of fuels;
    -automatic fuel ignition - pellets;
    -automatic fuel ignition – pea coal;
    -automatic fuel ignition – cereals;
    -wood
  • Automatic operation of the boiler controlled by weather controller and room thermostat;
  • To improve the quality of combustion Pellets Fuzzy Logic is fitted with three fans (two pressure and one exhaust);
    - exhaust fan
    - to eliminate odors and dust in the boiler room;
    during the combustion of fuels the fan draws flue gas from the boiler to the chimney. Fan rotor, through which flue gas pass, is made of stainless steel;
  • Door viewer - to not open the door during operation, a sight glass was mounted to view the flame;
  • Flue gas temperature measurement - this feature allows you to control the efficiency of the boiler and its settings. It informs you also about the point at which the boiler heat exchanger must be cleaned;
  • Two operation modes;
  • - summer - during the summer season domestic hot water is heated;
  • - weather - along with the external temperature sensor and the room temperature controller (standard boiler equipment);
  • Modulation of the burner operation by Fuzzy Logic method - no feeding and stan dstill times - automatic power adjustment to the heat demand of the building - from 10% to 100% of the boiler output;
  • Lambda probe - infinitely adjustable fan speed (air is tuned by the lambda probe and not by the user.
  • Just press the start button and the boiler will tune the amount of air itself;
  • Temperature limiter - the boiler is fitted with the temperature limiter, independent from the boiler control system, which operates at a temperature higher than 95°C; continuous feeder temperature measurement; fee der alarm condition temperature is programmable;
  • Automatic control of the mixing valve actuator; measurement and regulation of the temperature of the water returning to the boiler;
  • Possible domestic hot water heating;
  • Alphanumeric display with backlight - nice and easy to use; Menu in English, Polish, German;
  • Mechanical or electronic (optional) fuel level indicator
  • Economic operation
  • Low levels of harmful substances in flue gas;
  • High efficiency of the device
  • Versatile installation options (left / right side)
