Fournaises tubulaires

Trois zones

  • Utilisation innovante des espaces d'aération et d'isolation de l'air
  • Accepte un éventail d'adaptateurs de tubes (voir le tableau)
  • Conception flexible, peut être utilisé pour une variété d'applications

Three Zone 1100°C Tube Furnaces have new, energy efficient designs incorporating Lindberg/Blue M exclusive Moldatherm® ceramic fiber insulation.

Performance attributes include excellent temperature uniformity, fast heat-up and cool-down, and quick recovery with optimum power consumption. The furnace includes three independent, programmable controllers, one for each zone.


  • Innovative use of venting and insulating air spaces to create lower exterior surface temperatures
  • Accepts an array of tube adapters (see chart)
  • Flexible design, may be used for a variety of applications
  • One set of (2) tube adapters included; standard
  • Long-life Type "K" thermocouples
  • RS-485 communications port available as an option


Digital 16 Segment Programmable Controller

  • Three programmable controllers, one for each zone
  • Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process without overshoot
  • 1 program with 16 segments for ramps (up and down) and dwells (timed holds) each zone
  • Adjustable high limit overtemperature protection
  • Simultaneous LED display of actual temperature vs. setpoint
  • May be configured to display temperature in either °C or °F



Tube adapters
Tube adapters prevent heat loss and improve temperature uniformity within the furnace chamber by insulating the end vestibules. One set (2) of tube adapters provided with each Lindberg/Blue M furnace fits the largest diameter process tube specified for use with that furnace. Interchangeable tube adapters which allow alternative size process tubes are available; see chart.
