The Centorr Vacuum Industries Series 60 High Temperature Vacuum or Controlled Atmosphere, Front Access, Cold Wall, Refractory Metal, Laboratory Furnaces are simple and easy to operate.
A furnace system typically consists of the Basic Furnace Chamber Assembly, the High Vacuum System or Evacuation System, the Process Gas System, the Power Supply, the Temperature Control Instrumentation, and the Furnace Mounting Assembly.
The unit is ready to operate as soon as power is connected to the main circuit breaker, and water inlet and drain connections are made.
The Furnace is completely assembled and thoroughly tested prior to shipping; a copy of test results will accompany shipment.
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 Tungsten, Tantalum, Molybdenum, or Kanthal. Heating shielding is by concentric layers of metallic radiation shields. Heat zone components are readily accessible for inspection or maintenance. Provision is made for either suspending the work from above or for support by means of a work support hearth.
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.
Loading is done through the front door. Clamps are provided for operation to slightly above ambient pressure.
HIGH VACUUM SYSTEM
For operation in the 10-4 - 10-6 torr vacuum range of vacuum we supply a High Vacuum System. This system includes a High Speed Diffusion Pump, Cold Trap, Mechanical Pump, High Vacuum, Foreline, and Roughing Valves, Vent Valves, High Vacuum Elbow, and Vacuum Instrument. Systems can be fully Automatic, Semi-Automatic, or simply Manual.
PROCESS 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 Systems consist of Silicon Controlled Rectifier Power Controller (Saturable Core Reactors also available) with Current Limit, Step-down Transformer, Circuit Breaker, Contactor, Control Transformer, Ammeter, Voltmeter, Push Buttons, Indicator Lights, Water Interlocks, all completely wired and packaged in an attractive floor standing cabinet.
TEMPERATURE CONTROL INSTRUMENTATION
Centorr 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 Indicators- Controllers, Recorders, and Programmers. Various types of Micro-Processor Programmers are now available and extremely popular.
