Lindberg/Blue M™ 1700°C Box Furnaces with Integral Control

By Thermo
Lindberg/Blue M™ 1700°C Box Furnaces with Integral Control

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.

Energy-efficient double shell design means 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. A Moldatherm® hearthplate supports load and protects chamber from damage due to spillage. Side swing door provides full and easy access to chamber and protects user from heat surge. Removable panels allow easy access to replaceable heating elements and thermocouples.

Furnace has a 0.375" diameter atmosphere port for fresh air or inert gas inlet (located at back wall, bottom). 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 "Open Element," "Fuse" 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.

The Smart Heating Elements are molybdenum disilicide elements with unique right angle bend and sidewall mounting to reduce maintenance associated with element termination and mounting. These elements offer increased resistance to thermal shock, ideal for rapid cycling over extended periods. Designed for easy replacement without matching resistance values.

Digital, Single Setpoint Controller is a microprocessor-based PID control (proportional, integral, derivative) that prevents overshoot:

  • Single segment, single setpoint, 1 ramp to setpoint
  • Adjustable high limit overtemperature protection
  • 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 is also a microprocessor-based PID control but with multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control. LED display of actual temperature (°C or °F ). Contact Krackeler Scientific Customer Service for more information.

Programmable Control With Communications, available on "COM" models, has installed communications card and port for user connection. 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. Contact Krackeler Scientific Customer Service for more information.

Option B Overtemperature Control (OTC), adjustable digital overtemperature control available on selected models with "B" designation; protects furnace and load in the event of primary control circuit failure. OTC overrides main controller, assumes temperature control, 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.

Specifications: (For overtemperature control, specify Option B when ordering.)
