Lindberg 1100°C Moldatherm® Box Furnaces

Lindberg/Blue M Moldatherm^© 1100°C box furnaces feature a choice of microprocessor-based single set point 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 Set Point 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 set point, 1 ramp to set point
Adjustable high limit over temperature protection
Simultaneous LED display of actual temperature vs. set point

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. See page 35 for more information
Adjustable high limit over temperature protection
Simultaneous LED display of actual temperature vs. set point
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
