1700°C Box Furnace, Large Chamber, Integral Control
|
|
Large Chamber 1700°C Box Furnaces are designed for efficient, high temperature use with minimal maintenance. Moldathermâ 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.

General Features
|
Construction
- Available in two popular chamber sizes (see chart)
- Energy efficient double shell design for better uniformity, lower external cabinet temperature
- Moldathermâ 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, .375" diameter, for fresh air or inert gas inlet (located at back wall, bottom)
- Moldathermâ 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 "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
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

Controllers
|
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
- Simultaneous LED display of actual temperature vs. setpoint
- May be configured to display temperature in either °C or °F
Option P Digital 16 Segment Programmable Controller
- Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot
- 16 segments, 4 programs with 8 ramps (up and down) and 8 dwells (timed holds) each
- Simultaneous LED display of actual temperature vs. setpoint
- May be configured to display temperature in either °C or °F
Programmable Control With Communications
- Available on "COM" Models
- RS232 port allows modification and interrogation of all instrument control and
configuration parameters from remote computer (software not
included)
- Includes installed communications card and port for user connection
Option B Overtemperature Control (OTC)
- Adjustable digital overtemperature control, available on selected models 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 magnetic contacts through signal from independent thermocouple
- Factory installed, specify when ordering
