GENERAL INFORMATION

BASIC FURNACE CHAMBER ASSEMBLY

The Basic Furnace consists of a double wall all stainless Steel, water-jacketed chamber containing The Heat Zone. The heat zone is resistance heated. The Heating Element is made of Refractory Metal. 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 Vacuum Industries’ proprietary Rotatable Sight Window is included as standard equipment.

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 Thermocouple Gauge Vacuum Instrument.

PROCESS GAS SYSTEM

Process Gas System consists of Vacuum-Tight Gas Inlet Valve and Relief Valve, Bourdon type Pressure Vacuum Gauge and Manifold. Process gas systems capable of handling multiple gases, including gas mixing, mass flow control, and gas analysis are available as options.

For inert atmosphere operation, the use of an optional gettering furnace, such as the CENTORR Model O2, is highly recommended.

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. Power supply systems employing saturable core reactors are also available on request.

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 control circuitry ranging from the simplest Manual Power Control to the most sophisticated intelligent Instrumentation. These controls can include Automatic closed loop control utilizing Thermocouples, Power Transducers, or Optical Pyrometers for sensing; and can incorporate 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 a steel table.

EVACUATION SYSTEM

For operation in the 10-50 Microns range of vacuum or for evacuation prior to backfilling with desired process gas, 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.
