Box Furnace

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.

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 Moldathermâ 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" dia., top) and air inlet (.375" dia., rear) for inert atmosphere exchange
• Removable and replaceable Moldathermâ 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 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
• May be configured to display temperature in either °C or °F
• UL, CUL approval pending

Digital 16 segments programmable 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
• 16 segments, 1 program with 16ramps (up and down) and 16dwells (timed holds)
• Adjustable high limit overtemperature protection (optional)
• Simultaneous LED display of actualtemperature vs. setpoint
• May be configured to display temperature in either °C or °F
• 1 program with 16 segments for ramps (up and down) and dwells (timed holds)
