Furnace body

It adopts a double-layer water interlayer structure,The furnace body is also a double-layer water-cooled structure, and the middle is cooled by water. The inner walls are made of stainless steel (SUS304), the inner wall is strictly and precisely polished, and the outer wall is metal matt surface treatment. It is clean and beautiful, and it is easy to clean if the foreign body is dirty. The insulation layer inside the furnace body is composed of multi-layer molybdenum sheets and stainless steel sheets, and a special fixing method is adopted to reduce deformation.The "O" ring is used for vacuum sealing, and a water cooling device is installed (to prevent the "O" ring from aging due to excessive temperature). There are air extraction, air intake, thermocouple holes, etc.

Furnace door

It adopts a double-layer sandwich head structure and is cooled by water.

Furnace frame

It is welded into a box-type structure by section steel and steel plate, and the furnace body is placed on the box body, which is beautiful and generous.

Vacuum system

The vacuum system consists of one

STFJ-1200 Vortex molecular pump with 25L/S Rotary vane pump,manual high vacuum baffle valve, vacuum pressure gauge (±Pa), inflation valve, deflation valve and vacuum pipeline. the vacuum degree is measured by a digital display composite vacuum gauge.

Temaperature control

The power regulator is used to control the temperature, the instrument is Yudian instrument, with P.I.D adjustment, over-temperature sound and light alarm function, the electrical components are Chint brand, high temperature control accuracy, easy to operate

Gas system

There is one air inlet and one air outlet in the whole system, which can be filled with air.

Transformers and connecting cables

It use matching transformers and connecting cables

Water cooling system

It is composed of various pipeline valves and other related devices.

Electronic control system

The electronic control system adopts thyristor configuration, with P.I.D function instrument, multi-band digital display meter, and over-temperature sound and light alarm function.

Cooling system

The water cooling system is fed from the main pipe, and sent to the furnace body, furnace cover, furnace bottom, electrodes, vacuum pump and other places that need to be cooled through each branch pipe, and then collected and discharged. Each cooling water is equipped with a manual valve, which can adjust the flow according to the needs. There is an electric contact pressure gauge on the water inlet pipe, when the water pressure is lower than 0.1MPa, the heater can be automatically cut off.

Transformers and connecting cables

Use matching dry-type transformers and cables.

Heating element and heat shield

The heating element is a molybdenum wire structure and hangs vertically. When using it, its deformation should be observed to prevent short-circuit contact with the reflection screen in the furnace.

Warranty

One year limited warranty with lifetime support, excluding heating element,cooling fans,thermocouple damaged by user.

Attention: Any damages caused by the use of corrosive and acidic gases, and any damage from wrong operate and use are not under the coverage of One Year Limited Warranty.
