GENERAL SPECIFICATIONS
Note
* Inrush power and current.
** Power and current required to maintain maximum temperature after stabilization.
The maximum current is determined by the limiting factor set by the current controller. In the event
that 40 amperes is not available, the current controller may be set to limit the current to some small-
er value at the expense of a somewhat longer heatup time.
The variation in current is a result of molybdenum disilicide heating elements having a large
increase in resistance with increasing temperature.
The maximum ramp rates for this furnace for heatup are: 100° per minute from 25C-1000°C and
15°C per minute from 1000°C-1700°C.
