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.

FEATURES

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

*Process Tubes: These furnaces are designed for use with a variety of process tubes including alumina, mullite, quartz and metallic. Process tube is not supplied with furnace. For information on process tubes contact us. One set of (2) tube adapters included with furnace; largest specified size supplied.

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.
