2. THE HOT ZONE

Typical KSF Hot Zone assemblies include graphite resistance heating element, thermal insulation shielding,convection barriers, electrical isolations.
INSULATION
A graphite insulation is used. Access to the hot zone is through a removable top cover. 
A convection barrier prevents "short circuiting" of the insulation, allowing maximum temperature uniformity to 2200¡É
HEATING ELEMENT
The three phase heating element is supported by  water cooled power feedthroughs 
Water cooled power feedthroughs carrying high current from the transformer to the heating element. 
CRUCIBLE SYSTEM
The crucible is designed to support a temperature uniformly distributed load up to 2200¡É
Loading / Unloading of the crucible is performed by air-hydraulic operated automatic work loading system. 

3. WATER CIRCULATION SYSTEM

KGPS employes a Closed Drain Cooling Water System wich matches your existing plant water system. 

Includes is an inlet distribution manifold with a pressure gauge and separately valved circuits for chamber, power feedthrough and pumping system. Inlet and Outlet alarmed pressure switches warn both of low water flow rate and high water temperature. 
Cooling water is distibuted to the chamber, power feedthru, some types of optional pumps, and accessory modules.

4. GAS CONTROL SYSTEM

Automatic Inert Gas High Pressure Control System: 

The inert gas pressure control system can be manually adjusted or programmed to get best sintering condition. To prevent overpressurizing the vessel a relief valve sett point adjustable is provided. 

The control system employs a 0-2 bar pressure transducer, a modulating valve and a programmable microprocessor pressure controller, with digital read out of pressure. 

The vessel cover will be interlocked to prevent their being opened when the vessel pressure is above + 0.1bar. 

5. PUMPING SYSTEM

The pumping system consists of a two stage rotary vacuum pump and a mechanical booster pump, a vacuum manifolding with metal bellows vibration isolation, thermocouple gauge port, mass spectrometer port, automatic vent valve and automatic isolation valve. 
  Option: 

• DP - Diffusion Pump: 

To provide High vacuum level. Size and speed on request.

6. Control System

We propose different models equivalent Controllers from different manufacturer, so you can chose the Controllers matching your existing equipment. 

Control Cabinet is a 19" Standard Rack Mounted deep cabinet with one hinged front door.

The basic control equipment is:

• Power circuit breaker 
• Voltmeters, Ammeters, Alarm Panel 
• Vacuum gauge readout 
• Pump motor starters 
• PLC Logic Controller (PLC Direct) 
• Graphic Status Display / Operating Console
• Chino KP1000 Temperature Controller
• Konics 6 Channel recorder
• Cabinet Fan & Dust Filter 

• Double door cabinet (Double 19" Standard rack mounted deep cabinet for easy access inside of the cabinet) 
• Pirani gauge with dual setpoints controller for partial pressure (or equivalent instrument) 
• Penning Gauge (Cold Cathode Gauge) with Controller (for High Vacuum) -MKS 
• Double Konics 6 channel recorder (or equivalent) 
• Chino 32 channel recorder
• Touch Screen Operating Console
• Industrial Computer & Monitoring Software , Inkjet Color Printer
• Cabinet Air Conditioning 

7. POWER SUPPLY

The Power Supply is a saturable core reactor or variable reactance transformer with linear power controller, circuit breaker, undervoltage trip, and water cooled leads. 
The power supply is transformed from high voltage, low current to low voltage, high current.
