Product Description
This is the most advanced vacuum brazing oven currently available. It is have a fully intelligent control system, a complex temperature control process with one-click settings, and vacuum pressure management and control. It automatically runs the heat treatment process and performs every step in accordance with the requirements set by the engineer.
Not only that, all the vacuum pumps of this vacuum furnace have many sensors. If they encounter excessive temperature, motor overload, pressure loss, etc. during operation, they will automatically alarm and notify the engineer to intervene manually to avoid unnecessary losses.
The heating element inside the vacuum furnace body is molybdenum metal, and there are multiple layers of stainless steel reflection screens to prevent heat from spreading outward and ensure that heat will not be lost, thus reducing energy consumption.
The furnace body is design with a multi-layer structure, with a cooling water channel in the middle of the interlayer. During high-temperature operation at 700 °C, the temperature of the outer wall of the furnace shell will not exceed 35 °C, maintaining a comfortable temperature in the factory workshop.

The advantages of a vacuum brazing oven
- Multiple temperature monitors
There are 9 temperature monitors in the chamber of the vacuum furnace. It uses an N-type thermocouple to collect temperature data, and then controls the uniformity of the temperature through a PLC. The maximum temperature error is restriction within the range of 1 °C, meeting the need for precise temperature control. Aluminum brazing and other heat treatment processes.
- A faster rate of temperature rise
This brazing vacuum oven have a transformer, which can efficiently control the heating speed. The fastest heating speed per minute reaches 25 °C. It only takes 50 minutes to reach 650 °C. This rapid heating design can greatly improve work efficiency.
- Intelligent control system
The control system is the soul of the entire vacuum brazing furnace, which plays a crucial role in the quality of the product. Therefore, we preset a variety of operation modes for this control system, such as access mode, operation mode, maintenance mode, manager mode, etc. In order to avoid unprofessional engineers operating errors, resulting in significant losses.
- Strong load capacity
The vacuum oven body is a double-layer design, with reinforcing pillars distributed on both sides of the interlayer, which are welded and fixed. The pillars in the furnace are made of stainless steel, which has auxiliary support strengthening devices to share the load pressure on the wall of the furnace body, eliminate the deformation of the furnace body and increase the load capacity.
- Intelligent vacuum system
The vacuum pump has the ability to automatically control in operation. If it encounters a power outage, the vacuum valve will automatically close to ensure that the vacuum pressure in the furnace will not decrease. Not only that, but each vacuum pump can operate independently and can be locked to each other to prevent malfunctions caused by misoperation.

Vacuum pump system
- The vacuum system of this furnace is compose of a mechanical pump, a roots pump, a diffusion pump, a maintenance pump, etc. Each pump has a different function.
- The ultimate vacuum pressure of this vacuum furnace is 5 * 10-4pa. We have reserved some reserve capacity for each vacuum pump to ensure the efficiency of vacuuming.
- Each vacuum furnace has an isolation valve, allowing them to work independently without interfering with each other.
- An interface is reserved between the roots pump and the mechanical pump. Usually, this interface is closed. Its function is to facilitate the inspection of helium for leakage in the vacuum furnace.
- The diffusion pump has an independent oil temperature display and is connecte to a sensor. Engineers can check the temperature of the diffusion pump on the touch screen. If the oil temperature is too high, the control system will issue a warning.
