Lindberg/Blue M™ 1200°C LGO Box Furnaces
By Thermo
LGO Series Box Furnaces feature technical advances in heating elements, insulation, and temperature control, all integrated into a self-contained cabinet. The patented LGO™ heating element (light gauge overbend) delivers maximum radiant heat energy to the process load. The LGO™ element is imbedded within Lindberg/Blue M's exclusive Moldatherm® insulation, combined with unique double shell construction to provide temperature uniformity, energy efficiency, fast response, quick heat-up, and rapid cool-down. Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates.
Self-tuning, digital instrumentation for precise temperature setpoint and display automatically sets the best control parameter values during operation. Platinel II® thermocouple for long-term stability. Choice of side hinge or vertical lift door; see specifications for model selection. A safety door switch interrupts power to heating element when door is opened to protect heating elements and minimize exposure to end-user. The main power on/off switch is on a control panel that is designed for easy maintenance access. Moldatherm® hearthplate supports loadand prevents damage due to spillage.
Air vent (1" dia., top) and air inlet (.375" dia., rear) for inert atmosphere exchange. Removable shelves for versatility; 0.58 cu.ft. models include 1 two-part shelf, center position; 1.95 cu.ft. models have 3 shelf positions; 1 two-part shelf included standard.
Digital, Single Setpoint Controller, a microprocessor-based self-tuning PID control (proportional, integral, derivative), provides optimum thermal process, prevents overshoot.
- Single segment, single setpoint, 1 ramp to setpoint
- Adjustable high limit overtemperature protection
- Simultaneous LED display of actual temperature vs. setpoint
- Can be configured to display temperature in either °C or °F
Digital Single Program, Multiple Segment, Programmable Controller is similar to the single setpoint controller but provides a 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" designation, offers multiple programs and segments for ramp and dwell temperature control.
Adjustable digital overtemperature control (OTC), available on selected models with "B" designation, protects furnace and load in the event of primary control circuit failure by overriding the main controller, assuming temperature control and shutting off power to furnace if high limit is reached. Manual re-set required for safety. Operates via magnetic contacts through signal from independent thermocouple.
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. Contact Krackeler Scientific for ordering information.
Flowmeter Option (FM) (Inert Atmosphere Only), available on selected models with "FM" designation, includes a gas flowmeter on the front control panel. The flow rate is adjustable accross the range 1.0 to 10.0 cu.ft./hr standard. Suitable for inert gas or air flow to chamber; not suitable for combustible or volatile gases. Note: Use with inert atmosphere will exhibit some leakage.
