As we all know that precision hot air ovens have a wide range of applications. It can dry a variety of industrial materials and are general-purpose drying environment test equipment. And it has the characteristics of fast heating, good insulation, easy operation and safety.
The working principle of the precision hot air oven is to control the temperature through the connection of the digital display instrument and the temperature sensor. The hot air circulation air supply method is adopted. The hot air circulation system is divided into horizontal and vertical. The wind source is precisely calculated. The air source is driven by the air supply motor to drive the wind wheel through the electric heater to send the hot air to the air duct and enter the inner chamber. The used air is drawn into the air duct to become the air source and recirculated and heated. This will effectively improve temperature uniformity. If the door is opened or closed during use, the air circulation system can quickly back to the operating temperature value.
