Thermo Scientific LBM LGO Furn 55L A OTC – Lindberg/Blue M LGO Box Furnace, 100 to 1200 deg C, 55.3 L, Digital Single Setpoint Controller, OTC Over Temperature Controller, Horizontal Side Swing Door

• Feature exclusive LGO heating elements and Moldatherm insulation for efficient and economical transfer of heat to chamber, with low exterior temperatures
• Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates
• Air vent (1 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange; (Note: door is not gas-tight)
• Self-tuning, digital instrumentation for precise temperature setpoint and display
• Platinel II thermocouple for longterm stability

Utilize the latest technical advances in heating elements, insulation and temperature control integrated into a self-contained cabinet with Thermo Scientific Lindberg/Blue M LGO Box Furnaces. Furnaces feature proprietary LGO (light gauge overbend) heating elements and Thermo Scientific Moldatherm insulation for efficient and economical transfer of heat to chamber, with low exterior temperatures. Variable heat-up rate eliminates thermal shock to materials with inherently quick heat up and cool down rates.

• 0.6 cu.ft. models feature vertical lift door; 2 cu.ft. models feature horizontal side swing door, hot side facing away from operator for protection

Microprocessor Control

• Microprocessor-based self-tuning PID control provides optimum thermal process, prevents overshoot
• Control panel designed for easy access and maintenance
• Main power ON/OFF switch on control panel
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint in °C or °F
• Safety door switch interrupts power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
• Removable shelves for versatility
• Moldatherm hearthplate supports load and prevents damage due to spillage

Applications:

• Drying
• Ashing
• Annealing
• Enameling
• Tempering
• Heat treatment
• Melting

Digital Single-Program, Multiple-Segment Programmable Controller

• Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature 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

Overtemperature Control (OTC)

Adjustable digital overtemperature control, available on selected models with(B)suffix designation

• 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 reset required for safety
• Operates via magnetic contacts through signal from independent thermocouple
