1700°C BOX FURNACES, INDEPENDENT CONTROL

BF51314C Research and Pilot Plant Production
The General Purpose 1700°C Box Furnace with independent control are designed for applications which require extremely rapid heat-up rates, with 3500 watt models reaching 1700°C in as little as 15 minutes. Choose from two popular chamber sizes, each with a fully programmable independent controller (ordered separately, see specification chart).

General Features

Available in two popular chamber sizes (see chart)
Double shell design for lower external cabinet temperature and energy savings
Moldatherm^© high temperature ceramic fiber 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^© hearth plate 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 energy efficiency and operator safety
Long-life type "B" thermocouples with 10' compensated lead wire and polarized plug for accurate high temperature measurement

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

CONTROLLERS

CC59256PCOMC 1700°C Controller, Programmable, With Communications
Lindberg/Blue M 1700°C Programmable Controllers provide multiple programmable and multiple segments for ramp (up and down) and dwell (timed holds) temperature control. The controller visually displays ramp rate, dwell time, program segment and percent power output. A holdback feature allows the operator to set a "process vs. set point" temperature value which, when exceeded, holds the program to allow the process to catch up.

The controller includes a selectable self-tuning feature which automatically sets the best PID settings for the thermal process. LED display indicates actual temperature and set point temperature. High limit over temperature protection is standard. The control console includes a circuit breaker, power module, transformer and cooling fans.

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 Over Temperature Control (OTC)
Adjustable digital over temperature control, factory installed on selected control consoles with "B" designation; see chart. Protects furnace and load in the event of primary control circuit failure. 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 signal from independent thermocouple
