Model BF51866C

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.

General Features

• Two control options
• RS 485 communications port available as an option
• Controlled heat-up rate eliminates thermal shock to materials
• Quick heat-up and cool-down rates
• Energy efficient Moldatherm® insulation with fully embedded heating element
• 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"/25.4mm dia., top) and air inlet (.375"/9.5mm dia., rear) for inert atmosphere exchange
• 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 in 50/60H configurations.

Digital, Single Setpoint Controller

• Microprocessor-based control with advanced self-tuning feature automatically 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

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.
