Tubular furnace FHA series

thermalannealingcalcination

The FHA, single zone, and FHC, 3-zone, tube furnaces can be used either vertically or horizontally and have a maximum operating temperature of 1350 °C. The extensive F range of tube furnaces is offered with a wide range of accessories. The furnaces comprise ceramic fibre modules with a high quality 5 mm APM wire heating element mounted in the insulation, held in position by a ceramic holding ridge. The low thermal mass ceramic fibre insulation ensures low energy consumption and allows fast heating rates. The control thermocouple is a high grade type S thermocouple. Additionally, the tube furnace is available with up to 8 heating zones for the most precise temperature control and uniformity. Application Examples ageing, annealing, brazing, calcination, catalyst research, CIM, coating, CVD, degassing, drying, hardening, MIM, miniplants, pyrolysis, sintering, soldering, sublimation, synthesis, tempering, test fuel cells, thermocouple calibration Standard features Single zone models fitted with Carbolite Gero 3216CC PID controller with single ramp to setpoint and process timer 3-zone models fitted with 1 x programmable 3216CC and 2 x 3216CC end zone controllers, with retransmission of setpoint Accepts work tubes with outer diameters up to 110 mm Use in horizontal or vertical orientation Exceptional lifetime and temperature stability High grade type S thermocouple Low thermal mass ceramic fibre insulation High quality 5 mm APM wire as heating element Furnace fitted with separate control box with 3 m cable, plug and socket
