What temperature is needed for the application?Lindburg/Blue M FURNACES are listed by increasing maximumtemperature; 1100 C, 1200 C, 1500 C and 1700 What type of furnace is needed: box, tube or crucible?Each type of furnace may be used for many different types ofapplications. Here are some examples: A box furnace may beappropriate for processing large samples or for ease of placement andaccess of samples.

2 A tube furnace may be appropriate for processingsmall samples in inert atmospheres. A crucible furnace may beappropriate for processing samples in If a tube furnace seems appropriate for theapplication, please consider the following features:Will a single zone or three zone furnace be moreappropriate for the application?A single zone furnace has one set of heating elements controlled byone controller. A three zone furnace has three groups of heatingelements controlled by three controllers, one for each zone. A threezone furnace can be configured to help reduce the heat loss at thetube ends or to provide a gradient temperature along the length of a split-hinge or solid tube furnace needed?

3 A hinge tube furnace allows a process tube to be easily changed andremoved and may be appropriate if tubes must be changed on afrequent basis. A solid tube furnace may be appropriate if the tubewill not be changed or removed from the furnace on a frequent heated length is needed?The heated length of a tube furnace refers to the area covered by theheating elements. The heated length is noted for each tube furnace inthe size process tube will be used in the furnace ?Most of our tube FURNACES will accommodate a range of processtubesdue to our interchangeable tube adapters.

4 Please see the specifica-tions for each furnace model for this What type of controller is needed? A single setpoint, asingle program with multiple segments, or multipleprograms and multiple segments?A single setpoint provides one ramp up to one temperature single program, multiple segment controller provides one programwith multiple ramp (change in temperature) and dwell (temperaturehold) settings. A multiple program, multiple segment controllerallows multiple programs to be stored in the controller memory, witheach program offering multiple segments for temperature see page 35 for additional information on each type Are you concerned about saftey?

5 Will the furnace beleft running while unattended or overnight?We offer an Over Temperature Control (OTC) feature that provides aredundant, back-up thermocouple and controller to shut down thefurnace if the high temperature limit is reached. This requires a man-ual reset for optimum safety. This feature is designated by a B inthe model number suffix or is available as an option on other selectfurnaces. Please see individual furnace specifications for Lindberg/Blue M product line offers aversatile selection of small, medium and largechamber box FURNACES suitable for a variety ofindustrial and LABORATORY engineering and specialized con-struction techniques include variable densityinsulation, double shell cabinets, long-lifeheating elements and vertical, horizontal sideswing or swing down doors.
