Lindberg/Blue M™ LGO Box Furnaces

Key Features Choice of side hinge or vertical lift door Air vent (1 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange (may experience some leakage at door) Self-tuning, digital instrumentation for precise temperature setpoint and display Platinel II™ thermocouple for long-term stability 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 (proportional, integral, derivative) 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 Can be configured to display temperature in either °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 Digital, Single-Setpoint Controller Single segment, single setpoint, one ramp to setpoint Digital Single-Program, Multiple-Segment Programmable Controller Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control Digital Multiple-Program, Multiple-Segment Programmable Controller Available on models with (P) suffix designation Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control 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 Flowmeter Option (FM) (Inert Atmosphere Only) Available on selected models with (FM) designation Gas flowmeter, adjustable, located on front control panel Adjustable flowrate, range 1.0 to 10.0 cu. ft./hr. standard Suitable for inert gas or airflow to chamber Allows fresh air exchange for ashing applications Not suitable for combustible or volatile gases Ordering Information: Required power cord and hardwiring not included. Optional RS485 Digital Communications Port 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. †Specify Option B for Overtemperature Control (OTC) when ordering. Includes One two-part shelf (0.6 cu. ft. models have one shelf position at center position; 2.0 cu. ft. models have three shelf positions)
