Chamber: cylindrical, steel pressure vessel, carbon steel jacketed, designed for uniform water cooling. Full opening front door.
Hot Zone: furnace - molybdenum element with molybdenum/stainless steel insulation, molybdenum posts resting in sockets on the chamber bottom provide sturdy hearth support.
Vacuum Pumping System: mechanical booster pumping system, mechanical pump with blower; necessary valving, manifolding and vibration isolation.
Temperature Controls, Instruments, Power Supply; NEMA-1 control cabinet with front access door interlocked for safety.
Contains: pumping system control panel with pushbutton station and indicating lights, two station thermocouple gauge (1-1000 microns) to main chamber and pump, furnace power control with meters for power supply output (voltage and current on each phase), pushbutton and pilot light for control power and manual power control.
Other features: emergency stop button, automatic/manual control for heat mode and quench mode by means of status indicating programmer and three (3) mode controller using control signal from thermocouple, cooling system on/off push-button with pilot light, interlock and failsafe provisions, audible alarm for furnace over-temperature condition, and water flow interlocks to protect critical components.
Power Supply: 60 KVA low voltage saturable core reactor, 3-phase balanced; manual circuit breaker with under voltage release for alarm conditions.
