Process Tube Size

High purity fused quartz tube
Ø4" OD x 1400mm L  

Sliding Rails / Table

• Dual sliding rails made of Cr plated steel
• Sliding rail length: 1200 mm
• Driven by DC motor

Sliding Control
    

Automatic sliding is controlled by the temperature controller.  When the heating program is finished, the furnace will slide from right to left at the set speed. Air fans will blow heated area to achieve fast cooling.

• Sliding Range: 340mm
• Sliding Speed: 0-70 mm/s; adjustable

Heating Elements

8 pcs Paralleled Infrared Heating  ( 1200w each)

Thermocouple

K type, 1/4" Dia x 24" length

Temperature Controller

• PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
• Built-in overheating & thermocouple broken protection.
• Over temperature protection and alarm allows for operation without attendant(s).
• +/- 1 ºC temperature accuracy.
• RS485 Communications Port.
• PC Control:  
• An MTS-02 control module is included for PC control on this furnace.
• The new version of PC module is now compatible with Lab View 05/08/2014
• A laptop PC can be ordered for $500 together with the furnace. We recommend ordering a computer (laptop) from us to avoid software installation problems as we will perform installation and testing before shipping.
•                                    

Vacuum Flanges
   

Stainless steel vacuum flanges are installed on both ends of the tube.

Compliance

• CE Certified
• All electric components ( >24V) are UL / MET / CSA certified
• The furnace is ready to pass TUV(UL61010) or CSA certification at extra cost.               

Application Notes
   

• Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.12 MPa (absolute pressure).
• Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. 
• The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
• Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
• Quartz tubes should be replaced after every 10th use to ensure the best performance.
