Automatic bench of boiler biomass
Model GRA 125


Boiler including/understanding:
  • Automatic feeding since the silo.
  • Manual Lighting.
  • Ventilator of air inlet at variable speed.
  • Ventilator of support of pulling.
  • Circuit of spillplate of temperature integrated.

  • The bench of study of a multi-fuel is delivered, instrumented with technical and teaching handbook.
  • It is composed of an automatic boiler biomass HS TERM 15, 25 or 40 kw, of a domestic network hot water, a network heating high temperature by unit heater.
  • Silo of a volume of 600 L allowing to receive the storage of cereals, pellet, shredded wood, oil cake of colza…
  • The food to the boiler is done by an endless screw.
