STF55346C 1100C Tube Furnace

At Pacific Combustion, we carry a full line of Thermo Scientific Lindberg / Blue M tube furnaces. Of the Lindberg / Blue M line, we offer the 1100C 3 Zone STF55346C tube furnace. Lightweight and compact, the model is designed specifically for processes that require radial and linear temperature uniformity. Incorporating the signature Moldatherm ceramic fiber insulation with embedded heating elements, the STF55346C is able to heat up exceptionally fast to temperatures of 1100C whilst being able to cool down with optimum energy efficiency. Furthermore, the furnace also offers three separate and programmable controllers, one for each zone, allowing you to control each zone independently.

Additional Features of the STF55346C

  • 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 STF55346C

  • 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.
