Lindberg/Blue M™ LGO Box Furnaces
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.
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)
