• Built-in adjustable high limit overtemperature protection
• Simultaneous LED display of actual and setpoint temperatures in either °C or °F
• Silicon carbide heating elements for long-life, safety, and reliable service with maximum energy savings
• Safety door switch interrupts power to heating elements when the door is opened; protects elements and minimizes exposure to the operator
• Moldatherm hearth plate supports a load and protects the interior from spillage and mishandling

Thermo Scientific Lindberg/Blue M Multipurpose 1500°C Box Furnaces have a double-wall construction with Moldatherm insulation for rapid heat up and cool down, energy efficiency, and cooler exterior surface temperatures.

• Built-in adjustable high limit overtemperature protection
• Simultaneous LED display of actual and setpoint temperatures in either °C or °F
• Silicon carbide heating elements for long-life, safety, and reliable service with maximum energy savings
• Safety door switch interrupts power to heating elements when the door is opened; protects elements and minimizes exposure to the operator
• Moldatherm hearth plate supports a load and protects the interior from spillage and mishandling
• Type “R” thermocouple is integrated into chamber back wall
• Double-wall construction with Moldatherm insulation for rapid heat up and cool down, energy efficiency, and cooler exterior surface temperatures
• Adjustable high-limit overtemperature protection
• Microprocessor-based PID control
• 6L models with vertical lift door

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

Over-temperature control (OTC):

• Adjustable digital over-temperature control protects furnace and load in the event of primary control circuit failure
• 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 independent thermocouple

Applications

• Annealing
• Melting
• Heat treatment
• Brazing
• Alloying
