GSL-1700X-HV series furnace consists of a high-temperature alumina tube furnace and a high vacuum system.

It can be heated up to 1700°C by a different type of MoSi2 heating elements and achieve vacuum pressure up to 10^-5torr with a diaphragm pump. It is widely used for material or chemical lab to sinter all types of new material samples under vacuum or other gas conditions. The temperature of GSL1700X tube furnace is controlled by 30 segments programmable high precision SCR power controller with accuracy +/-1°C.

Working Range

From standard atmosphere to <E-5 mbar (under Cold Condition only; with special
 tube block) 
(Noted: Please don't use high vacuum if the temperature is over 1500 °C)

Motorized Valve

  •      •  Flange in and out: DN 16 ISO-KF
  •      •  Ambient temperature: 5-40 °C (41-104 °F)
  •      •  Gas flow controllable range: 3.75×10E-6~937.5
             Torr l/s
  •      •  Operating pressure: 7.5×10E-9 to 1875 torr
  •      •  With integrated motor control electronics
  •      •  Fluoroelastomer Dosing sleeve

  •      •  The motorized Valve is used together with a control
            unit for controlling the pressure in a vacuum system,
            with a variable gas flow (upstream control)
            maintaining a desired vacuum pressure. More
            specifically, the control valve regulates the gas inlet
            of the vacuum system.
  •      •  The valve plate moves in closing direction when the
            pressure in the vacuum system rises, vice and verse.

High Vacuum Station


Mobile cart size:  600 (L) x 600 (W) x 700(H), mm

Max. Loading:       600 Lbs on top
Molecular pump control Panel :   LCD digital
Inside:   Pfeiffer vacuum pump  made in Germany
Vacuum sensor is included

Vacuum sensor

Two vacuum gauges are installed in this system.

1.Mechanical vacuum gauge

2.High vacuum gauge (measuring range 10^-8 mbar ~ 10^3 mbar) is installed in the whole high vacuum system for monitoring the high vacuum status when operating the furnace with HV station support.

Control Panel

One button operation
 - the diaphragm pump and the turbo molecular pump will start after pressing "start" button.

System controlled spinning speed - the controller will control the speed of the turbine spinning up and down according to the vacuum level and leaking rate of the reaction chamber.
Self-protection - the system will protect the pump from damage by overheating and overcurrent if the leaking rate of the reaction chamber is too high to achieve a high vacuum.
LCD screen - double lines parameters checking interface
 make the working easier to be handled.
