Lindberg/Blue M™ LGO Box Furnaces (Thermo Scientific™)

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

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)
