The furnace can be equipped with a gas pre-heating system specially designed. The entire pre-heater is made of 316L stainless steel, ensuring durability and resistance to corrosion. It allows pre-heating of various gases, including corrosive gases, to meet special process requirements. The maximum pre-heating temperature reaches 600°C.

Safety and Operating Instructions:

1. Do not open the furnace chamber when the temperature is ≥300°C to avoid personal injury.

2. The pressure inside the furnace tube must not exceed 0.125 MPa (absolute pressure) during operation, in order to prevent equipment damage.

3. When operating under vacuum conditions, the maximum allowable temperature is 800°C.

4. Since gas cylinders are supplied at high pressure, a pressure-reducing valve must be installed before introducing gas into the furnace tube. It is recommended to use a low-pressure regulator with a range of 0.01 MPa – 0.15 MPa for higher precision and safety.

5. When the furnace temperature is above 1000°C, the tube must not remain under vacuum. The internal pressure should be maintained close to atmospheric pressure (ambient pressure).

6. For high-purity quartz tubes, the maximum recommended continuous operating temperature is ≤1100°C.

7. During heating experiments, it is not recommended to completely close both the inlet and outlet valves on the tube flange. If closed-valve heating is required, the pressure gauge must be closely monitored. If the absolute pressure exceeds 0.15 MPa, the exhaust valve must be opened immediately to prevent accidents (e.g., tube rupture or flange ejection).

8. This equipment is recommended for micron-sized powders or granular samples. The use of nano-powders is not advised with this model.
