STF55666C 1100C Tube Furnace

Part of the high quality Thermo Scientific Lindberg / Blue M tube furnace line here at Pacific Combustion, The STF55666C 1100C tube furnace uses special Moldatherm ceramic fiber insulation with embedded heating elements as part of a new, energy efficient design. The furnace is able to perform quickly at temperatures up to 1100C whilst also displaying quicky recovery times within optimum power comsumption standards. Included are three separate digital controllers, one for each zone, allowing you to program each zone to your specific requirements. These unique features sets the STF55666C up specifically for all your processes that require radial and linear temperature uniformity through single program with multiple segment temperature control. The main differences with the STF55346C furnace model are the larger process tubes (3" to 6") and larger heated zones (36").

Additional Features of the STF55666C

  • Compatible with a large range of different process tubes including alumina, mullite, quartz and metallic
  • Able to create lower exterior surface temperatures through innovative use of venting and insulating air spaces
  • Flexible and lightweight design allowing you to use the furnace for a variety of applications (see below)
  • One set of (2) tube adapters are included as standard
  • Long-life Type K thermocouples

Uses of the STF55666C

  • Annealing
  • Crystal Growing
  • Calibration
  • Heat Treating

Features of Digital 16 Segment Programmable Controller

  • Three programmable controllers, giving the user one for each zone to control temperatures separately
  • Microprocessor-based self-tuning PID control (proportional, integral, derivative) providing optimum thermal process without any overshoot
  • 1 program with 16 segments. Every segment contains one ramp and dwell allowing you to set 16 ramp/dwell cycles.
  • Adjustable high limit over-temperature protection through super control (fuzzy logic)
  • Simultaneous LED display of actual temperature vs setpoint
  • May be configured to display temperature in either C or F

Optional RS485 Digital Communications Port

  • RS485 Digital communications port is available as an option. This port allows the controller to be connected to a PC for remote monitoring and control of the furnace, with up to 30 units being able to connect to one PC.
