• Unique insulation and heating element composites minimize outer surface temperatures while maintaining uniform heat distribution within the chamber
• Advanced engineering and specialized construction techniques include variable density insulation, double shell cabinets, long-life heating elements, and horizontal side swing doors
• Selectable self-tuning feature sets control parameters for the thermal process
• PID control prevents temperature overshoot
• Main power ON/OFF switch on the control panel
• Controlled heat-up rate eliminates thermal shock to materials
• Quick heat-up and cool-down rates
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint (°C or °F)

Advanced Construction

• Advanced double-wall 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 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange; (Note: the door is not gas-tight)
• Removable and replaceable Moldatherm hearth plate supports a load and prevents damage due to spillage
• Energy-efficient Moldatherm insulation with embedded heating elements
• Safety door switch to interrupt power to the heating element when the door is opened; protects heating element and minimizes exposure to end-user

B: Digital Single-Program, Multiple-Segment Programmable Control

• Single program with 16 segments for ramp (up and down) and dwell (timed hold) temperature control
• Simultaneous LED display of actual temperature vs setpoint
• Super Control (Fuzzy logic) suppresses overshooting of temperature
• Customer initiated auto-tune function will adjust and update the PID parameters to the optimum settings for new temperature setpoints

D: Over-Temperature Control (OTC):

• Adjustable digital over-temperature control protects furnace and load in the event of primary control circuit failure available on selected models with “B” suffix designation; see spec table
• Overrides main controller and shuts off power to furnace if high limit is reached
• Manual re-set required for safety
• Operates via magnetic contacts through a signal from the independent thermocouple
