Dual Zone Quartz tubular furnace
1.Features of Dual Zone Quartz Tube Furnace :
(1). Operation Temperature: 1100°C  ( 1200°C for short time). 
(2). Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
(3). Heavy duty double layer structure with cooling fan. Lower temperature in outside case. 
(4). PID automatic control via current limiting phase angle fired the resistor, e.g. SCR(Silicon Controlled Rectifier).             
(5). Power control with 30 segments programmable. 

We have a wide range of different optional function furnace to meet different heating requirement, also we accept customer design furnace R&D working, please email us your specific requirement, we will recommend most reasonable choice for you, thanks!
