Lindberg / Blue M 1700°C Large Chamber Integral Control Box Furnaces
from Thermo Fisher Scientific
Large Chamber 1700°C Box Furnaces are designed for efficient, high temperature use with minimal maintenance.
- Moldatherm® graduated density insulation adds to safety and performance by forming enhanced insulation protection between the high temperature chamber and exterior cabinet surface.
- Unique right angle heating elements and an integrated control system (a choice of single setpoint or programmable control) combine to deliver safe, dependable operation.
Applications
- Sintering.
- Ashing.
- Bonding.
- Melting.
- Metals and ceramic composites.
Construction
- Available in two popular chamber sizes.
- Energy efficient double shell design for better uniformity, lower external cabinet temperature.
- Moldatherm high temperature ceramic fiber insulation with advanced graded design for fast heat-up and resistance to thermal shock.
- Side swing door provides full and easy access to chamber, protects user from heat surge.
- Removable panels for easy access to replaceable heating elements and thermocouples.
- Atmosphere port, 0.375" diameter, for fresh air or inert gas inlet (located at back wall, bottom).
- Moldatherm hearthplate supports load and protects chamber from damage due to spillage.
- High volume cooling fans move air between inner and outer chamber to lower exterior shell temperatures and improve energy efficiency.
- Solid-state power module with ammeter, circuit breaker, transformer and front panel indicator lights for “Ready Element” and “Main Power Applied”.
- Long-life type “B” thermocouples for accurate high temperature measurement.
- Safety power disconnect switch cuts power to heating elements when door is opened.
Smart Heating Elements
- Molybdenum disilicide elements with unique right angle bend and sidewall mounting to reduce maintenance associated with element termination and mounting.
- Energy efficient, fast heat-up and response.
- Increased resistance to thermal shock, ideal for rapid cycling over extended periods.
- Designed for easy replacement without matching resistance values.
Digital, Single Setpoint Controller
- Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot.
- Single segment, single setpoint, 1 ramp to setpoint.
- Adjustable high limit overtemperature protection (OTP).
- Simultaneous LED display of actual temperature vs. setpoint.
- May be configured to display temperature in either °C or °F.
Option P Digital Multiple Program, Multiple Segment Programmable Controller
- Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot.
- Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control.
- LED display of actual temperature.
- May be configured to display temperature in either °C or °F.
Programmable Control With Communications
- Available on “COM” Models.
- Controllers include RS485 data port (communications card and port) for connection to remote computer, allowing modification, interrogation and data transfer of all instrument control and configuration parameter.
- Up to 30 units can be connected to one PC.
- Software is not included, but is available as an option.
- Includes installed communications card and port for user connection.
Option B 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 re-set required for safety.
- Operates via magnetic contacts through signal from independent thermocouple.
- Factory installed, specify when ordering.
