GENERAL INFORMATION
BASIC FURNACE CHAMBER ASSEMBLY
The Basic Furnace consists of a double-wall all stainless steel (304L), water-jacketed chamber inside of which is the Heat Zone. The Heat Zone is resistance heated. The Heating Element is made of Refractory Metal (or Kanthal). The Heat Shields are also all Metal, Heat Zone components are easily accessible for inspection or maintenance. A Hearth is provided for work support.
The entire inside of the furnace chamber is designed to conform to the best High Vacuum Practice. Particular attention is given to the choice of heat zone materials and to surface finishes. Ports are provided for Sighting, Thermocouples, Evacuation, Inert Gas inlet and exit, Gauges, etc. Centorr’s proprietary Rotatable Sight Window is included as standard equipment. Loading is done through the Top Access Lid. Clamps are provided for operation to slightly above ambient pressure.
HIGH VACUUM SYSTEM
Standard High Vacuum Systems consist of High Vacuum Elbow; Diffusion Pump with Cold Trap; Mechanical Pump; Manual, Semi-Automatic, or Fully Automatic Valve System; all Copper Manifold; Viton "O" rings; and Combination Ion Gauge & Two-Station T.C. Gauge Vacuum Instrument.
POWER GAS SYSTEM
Process Gas System consists of Vacuum-Tight Gas Inlet Valve and Relief Valve, Bourdon– type Pressure Vacuum Gauge and Manifold.
POWER SUPPLY SYSTEM
Power Supply System consists of Silicon Controlled Rectifier Power Controller (Saturable Core Reactors also available) with Current Limit, Stepdown Transformer, Ammeter, Voltmeter, Push Buttons, Indicator Lights, Water Interlocks, all completely wired and packaged in an attractive floor standing cabinet.
Utility requirements are given in KVA at customer's Primary Voltage, Single or Three Phase, and 50 or 60 Hertz.
TEMPERATURE CONTROL INSTRUMENTATION
Centorr/Vacuum Industries can supply from the simplest Manual Power Control to the most elaborate Instrumentation. This can include Automatic closed loop control utilizing Thermocouples, Power Transducers, or Optical Pyrometers for sensing; and incorporating Indicator-Controllers, Recorders, and Programmers. Various types of Micro-Processor Programmers are now available and extremely popular.
FURNACE MOUNTING ASSEMBLY
The Furnace Chamber is mounted on an open support frame. Legs are provided with Leveling Pads.
EVACUATION SYSTEM
For operation in the 10-50 Microns range of vacuum or for evacuation prior to backfilling with Inert Gas or Nitrogen, we include an Evacuation System. This includes a Mechanical Vacuum Pump, Vacuum Valve, and Manifold. Line Filter ahead of the vacuum pump, and Thermocouple type Vacuum Instrument are optionally available.
