7 Zones 1200C Max. 5" Tube Furnace w/ Temperature Controller & Quick Flange - OTF-1200X-VII-5-UL

OTF-1200X-VII-5 is a Seven-zone 5“ split tube furnace with a separated temperature control unit and max working temperature of 1200 o C. This seven-zone furnace can create a step thermal gradient or one long constant temperature zone up to 35" by adjusting seven zone temperature. The furnace installed with 5" quartz tube and quick flange, and also can accept various processing tubes from 1" to 4".

SPECIFICATIONS:

Note	OTF-1200X-VII-5 is updated based on OTF-1200X-VII from Jan. 20, 2014
Furnace Structure	Double-layer steel case with air cooling to ensure furnace surface temperature < 60 °C Energy-saving high purity fibrous alumina insulation. Heating Element: 1300ºC  grade Fe-Cr-Al Alloy doped by Mo 41 "length x 5.5"dia heating chamber with 7 built-in thermal couples to accept processing tube from 1" - 5" dia.x2000 mm length The splittable cover is lifted and closed by a pair of heavy-duty compressed air springs to make tube replacement at easy.

Quartz tube & Thermal Block Placement	Quartz Tube: 130 OD x122 ID x2000 L mm (5"x 79")  (The tube is consumable , click picture below to order spare ) Two fibrous alumina thermal blocks are included , which must be placed on two end of inside tube ( click pic below right )
Vacuum Flange	One pair stainless steel vacuum flange is included with quick assembling flange ( a outside clamp for quick installation) Left flange installed with needle valve with 1/4" pipe port for gas inlet ( Pic below left ) Righ flange built in K25 port and Anti-Corrosive digital vacuum gauge to connect a vacuum pump
Heating Zone	Seven independent heating zones:   each heating zone length  150 mm ( 6") Total zone length: 1050 mm ( 42 )  Max. Constant temperature zone 35"  ( 875 mm ) if 7 zones heated  at the same temperature ( within +/- 2  °C)
Temperature Controllers	One touch screen digital temperature controller built-in a separated unit, which can control seven heating zones independently Each channel is PID automatically controlled and saves 10 programs and each program has max. 30 segments Built-in overheating & broken thermocouple protection. +/- 1 ºC temperature accuracy. Seven K-type thermocouples (one for each zone). RS485 Communications Port built-in. and software included,  The furnace may be operated by PC ( please order PC separately ).
Optionals	You may add a multi-channel gas delivery system under bottom table  for CVD or atmosphere control applications ( click PIC below-left to order ) You may consider a pressure control unit to keep constant pressure ( click picture below right to order )
Software & WiFi Control (Optional)	Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use. Labview Based Temperature Control System (MTS01) enables users to edit temperature profiles, manage heat-treatment recipes, record and plot data for MTI furnaces. A wireless remote control provides up to 300 meters of operating range. The above features are available upon request at an extra cost (up to $1,000). Please contact us for more information.
Compliance	CE Certified The furnace is ready to pass NRTLor CSA certification at extra cost.
Notice	In order to obtain an accurate temperature inside the tube furnace, you need to calibrate the temperature by yourself. Please click here to learn how.
Warning Click here to learn the installation of a gas regulator	The tube furnaces with quartz/mullite tubes are designed for use under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. * Vacuum pressures may only be safely used up to 1000°C   The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
