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 Solid Graphite. Heat shielding is by Graphite Felt pressed into solid form. Heat zone components are readily accessible for inspection or maintenance.
The entire inside of the furnace chamber is designed to conform to the best High VacuumPractice. 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 with gas port is included as standard equipment.
Loading is done through easily opened lids at either end of the Furnace Chamber. Lids are held in place by screws which permit operation to slightly above ambient pressure.
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.
PROCESS GAS SYSTEM
Process Gas Systems consist 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, Stepdown Transformer, Circuit Breaker, Contractor, Control 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.
OPTIONS - MUFFLE TUBE KIT
For Operating in Oxidizing Atmospheres, these furnaces can be supplied with a Refractory Muff to the furnace at both ends. Muffle tube kits can also be provided with closure lids with ports for gas inlet and exit, and/or sight windows or thermocouples.
