Boilers with feeder biomass

Bio Slim

End of problems with the selection of boiler pellet into a small boiler room.

  • Fuel tank placed directly over the heat exchanger minimizes the size of the boiler
  • Sleek and powerful burner pellet made from the finest materials with automatic cleaning
  • Horizontal tubular heat exchanger
  • Easy operation and maintenance, access to czyszczenai heating surface by a large front door of the boiler
  • Save space in the boiler room, the boiler requires only 1m2
  • Economizers in passageways combustion increasing precipitation of dust from the flue gases and raising the degree of heat exchange
  • Low operating costs
  • Exhaust fan eliminates the problem of improper chimney draft and stabilizing the operation of the boiler
