Serie BT DSNM-D

Technical and functional features

  • Heavy oil burners.
  • Two-stage operation (high/low flame).
  • Compatible with any type of combustion chamber.
  • High pressure mechanical atomisation of fuel using nozzle.
  • Ability to obtain optimal combustion values by regulating combustion air and blast-pipe.
  • Maintenance facilitated by the fact that the atomisation unit can be removed without having to remove the burner from the boiler.
  • Air flow regulation for first and second stage by means of electric servomotor with pause closure of gate to prevent any heat dispersion to flue.
  • Comes with 2 flexible oil pipes, 1 self cleaning and heated heavy oil filter, 1 flange and 1 insulating seal to connect the burner to the application. Nozzle must be ordered separately according to the burner nominal output reqired..
