• Burn-off Furnaces from Carbolite

Burn-off Furnaces from Carbolite

  • 1100 °C or 1200 °C maximum operating temperature
  • Good uniformity & compensation for heat loss from graded wire wound elements in side mounted, hard wearing alumina carriers
  • Hard wearing alumina element carrier, furnace entrance and hearth

The BWF burn-off furnace is designed to promote burning of combustible materials.


The airflow in the BWF is enhanced by the addition of a tall chimney and air inlet holes in the door, which rapidly remove the fumes from the furnace.
 

Features:

  • 1100 °C or 1200 °C maximum operating temperature
  • Good uniformity & compensation for heat loss from graded wire wound elements in side mounted, hard wearing alumina carriers
  • Hard wearing alumina element carrier, furnace entrance and hearth
  • Enhanced airflow from high chimney & door vents for full combustion
  • Carbolite 301 PID controller with single ramp to setpoint and process timer

Options (specify these at time of order) 

  • Optional racks & hearth trays
  • A range of sophisticated digital controllers, multisegment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications.
