Heating chamber: adopts box type heating chamber structure. The microwave shield grid ensure max safety operation; structure lined with high purity polycrystalline alumina fiber to achieve good temperature uniformity and for superior temperature presevation. It stands for a long service life, good thermal insulation performance, and minimal vacuum outgassing.


Heating control: PID intelligent temperature control module design, can edit 40 segments of temperature heating profile, store 20000 groups of process curves, combined with PLC, etc. to achieve automatic alarm protection functions such as over-pressure, over-temperature, over-current, 7-in or 10-inch touch screen display .



Water cooling system:

It is used to coool vacuum furnace body, door, vacuum unit, and water-cooled electrodes, and magnetrons. The system is distributed to each cooling part by the main water supply pipe. It uses a round-way water circulation system. Each electrode is equipped with a water flow observer and the main road is equipped with a water pressure alarm system.


Security system:

The safety system includes: water supply cut-off, over-temperature, over-current, rotary vane pump, molecular pump. The equipment has functions such as self-test, fault self-diagnosis, automatic protection, and prevention of misoperation. It has audible and visual alarm prompts and interlocking protection.


the microwave power is produced by 1 independent 1500W magnetrons allowing a maximum output power of 1.4kw. the microwave power is continuously adjustable from 15% to 100%. the mganetrons are water-cooled in order to ensure an optimum cooling and continuous operation at maximum effort.
