Lindberg/Blue M™ 1700°C Box Furnaces

Designed for applications which require extremely rapid heat-up rates, with 3500 watt models reaching 1700°C in as little as 15 minutes, Thermo Scientific™ Lindberg/Blue M™ 1700°C Box Furnaces with Independent Control are available in two popular chamber sizes, each with a fully programmable independent controller (ordered separately).

Features

• Available in two popular chamber sizes
• Double shell design for lower external cabinet temperature with energy savings
• Moldatherm™ high temperature ceramic fibre insulation with advanced graded design for fast heat-up and resistance to thermal shock
• Vertically hinged door lifts up and out of the way to save space and minimize exposure to the operator
• Removable panels for easy access to replaceable heating elements and thermocouples
• Moldatherm hearthplate supports load and protects chamber from spills or mishandling
• High volume cooling fans move air between inner and outer chamber to reduce exterior shell temperatures and improve

Smart Heating Elements

• Molybdenum disilicide elements with unique right angle bend and sidewall mounting reduce maintenance usually associated with element termination and mounting
• Designed for easy replacement without matching resistance values
• Fast heat-up and recovery with excellent uniformity and energy efficiency
• Increased resistance to thermal shock, ideal for rapid cycling over extended periods

1700°C Controller, Programmable, with Communications

• Provide multiple programs and multiple segments for ramp (up and down) and dwell (timed hold) temperature control
• Visually displays ramp rate, dwell time, program segment and percent power out-put
• Holdback feature allows the operator to set a process vs setpoint temperature value which, when exceeded, holds the program to allow the process to catch up
• Includes a selectable self-tuning feature which sets the best PID settings for the thermal process
• LED display indicates actual temperature (high limit overtemperature protection is standard)
• Control console includes a circuit breaker, power module, transformer and cooling fans
• 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.

Option B Overtemperature Control (OTC)

• Adjustable digital overtemperature control, factory installed on selected control consoles 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 signal from independent thermocouple
