The Lindberg/Blue M product line offers a versatile selection of small, medium and large chamber box furnaces suitable for a variety of industrial and laboratory applications. Advanced engineering and specialized construction techniques include variable density insulation, double shell cabinets, long-life heating elements and vertical, horizontal side swing or swing down doors.

Lindberg/Blue M Moldatherm 1100°C box furnaces feature a choice of microprocessor-based single setpoint or programmable control instrumentation. Available in four popular chamber sizes to meet the most demanding laboratory applications, these furnaces include unique insulation and heating element composites to minimize outer surface temperatures while maintaining uniform heat distribution within the chamber.

NOT AVAILABLE IN EUROPE.


Features and Benefits

• Two control options
• Controlled heat-up rate eliminates thermal shock to materials
• Quick heat-up and cool-down rates
• Energy efficient Moldatherm insulation with embedded heating elements
• Unique double-wall construction minimizes exterior surface temperatures for operator safety and energy efficiency
• Side-hinge door for convenient operation and full chamber access
• Long-life Type “K” thermocouple
• Air vent (1" dia., top) and air inlet (.375" dia., rear) for inert atmosphere exchange. Will experience some leakage at door
• Removable and replaceable Moldatherm hearth plate supports load and prevents damage due to spillage
• Main power on/off switch on control panel
• Safety door switch to interrupt power to heating element when door is opened; protects heating element and minimizes exposure to end-user
• Available in 120V and 208/240V configurations

Digital, Single Setpoint Controller

• Microprocessor-based control with selectable self-tuning feature sets best control parameters for the thermal process. PID control (proportional, integral, derivative) prevents overshoot
• Single segment, single setpoint, 1 ramp to setpoint
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• May be configured to display temperature in either C or F
• UL approval

Digital Single Program, Multiple Segment Programmable Controller

• Microprocessor-based control with selectable self-tuning feature sets best control parameters for the thermal process. PID control (proportional, integral, derivative) prevents overshoot
• Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control.
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• May be configured to display temperature in either C or F
• UL approval

Optional RS485 Digital Communications Port

• RS485 Digital communications port available as an option. Allows controller to be connected to a PC for remote monitoring and control of the furnace. Up to 30 units can be connected to one PC. Please see page 35 for ordering information and additional options
