1500C 8-Zone Split Tube Furnace For Thermal Gradient Processing - OTF-1500X-Z8

Please email for lead time
Item Number: OTF-1500X-Z8
Transported by LTL Freight (Truck)
OTF-1500X-Z8  is an eight-zone tube furnace with a mullite tube and conventional flange working up to 1500°C.. Each SiC heating element is controlled by an independent temperature controller to create the various thermal gradient for special processing in material research, such as gradient functional material, high-through phase transition and re-crystallization, etc.

Power Input 9KW
Working Voltage  AC208 - 240V,  Single phase 50/60Hz ( 50 A breaker required)
Max. Working Temperature 1500°C
 Working Temperature 1400°C (Continuously)
Recommend Heating rate 5°C/min.

Application Notes

  • The tube furnaces with mullite tubes are designed for use under vacuum and low pressure < 0.02 Mpa
  • Never use graphite crucible in alumina tube.
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Please click here to learn the installation of a gas regulator. 
  • The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
  •  Vacuum pressures may only be safely used up to 1300°C
Dimensions Furnace only: 35" × 23" × 30"
Operation Instructions

  • One-year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.).  
  • ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of MTI One Year Limited Warranty.
Laptop, software & WiFi Control (Optional)
  • Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) 
  • Labview Based Temperature Control System (EQ-MTS01) enables users to edit temperature profiles, manage heat-treatment recipes, record and plot data for MTI furnaces.
