• In order to achieve the Max. cooling rate, move the heated furnace from hot zone to cold zone

Warranty

One year limited warranty with lifetime support.

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.
For operating PECVD system with tube size larger than 4", please always keep more than 1-meter distance from the plasma source after the plasma generator starts working.
