Vertical Tube Furnace

The VTL1200/VTL1400/VTL1600/VTL1700 series has many advantages:even temperature,low surface temperature,heating or cooling promptly,energy saving and so on. it is an ideal muffle furnace for high temperature atmosphere sintering,atmosphere reducing,CVD experiment,vacuum annealing in industry,scientific research institutes and universities, which offer heating element of MoSi2 and double walled housing,Phase-shift trigger,Controlled silicon.Temperature controller is Shimaden 40-segments digital controller imported from Japan. Stainless steel flanges seal are connected with both ends of the tube, the flanges are equipped with gas fitting,valve and pressure gauge, with these accessories, vacuum level can be 10-3 Pa when vacuum. This furnace is vertical and split furnace, the body is fixed on the brace, there are supports to fix the tube and flanges, it is convenient and simple to operate the furnace.

Product Features:
1.Temperature controller: Shimaden FP93 (1)40 programmable segments (Shimaden fp93 made in Japan), It can separate into 4,2,1 programs, ie. 4x10 segments.
(2)FP93 have 6 PID controls, different PID are used for low,middle,high temperature for precise control.
(3)Over-temperature and over-current protection, shutdown automatically when the thermocouple is broken( it will shut down power when temperature is higher than 1620 ℃ or the thermocouples is broken, "ON" on the board is off and "OFF" is on)
(4)There is Fahrenheit (F) scale and Celsius (C) scale for option.
(5)With 485 communication interface: which can stop the furnace automatically.
2.Cover opening protection system: overtravel-limit switch is installed to protect user, it will cut off power when the cover open.
3.Chamber:it is imported from Japan, good performance of heat preservation, high reflectivity,even temperature field, good ability of anti thermal expansion and cold contraction.
4.Heating elements:This furnace is installed with MoSi2 to ensure uniform temperature field and long service life.
5.Leakage protection function:the furnace is installed with leakage air switch, it will cut off power automatically when electricity leak or current exceed rated current.
6.Software controlling system:this furnace can control every parameter directly and observe PV and SV on the computer by communication interface and software, computer can draw and save actual heating curve, it is convenient to call these dates at any time.
7.Controlling system:
Power control: Chint; Controlled silicon:Germany Semikron 106/16E; Trigger:Phase-shift trigger
8.Vacuum system: Vacuum level can be 10-1 or 10-4 with German molecular pump. TW-1.5 vacuum pump is for option.
9.Gas system:floating flow meter or digital flow meter is for option to control gas Speed.
10.Flange: with double ring sealing flanges, there are many adapter of the flanges to connect digital vacuum gauge,K25 vacuum Bellow. It can be made as hinge for removing conveniently.
