Nitrogen Hot Air Circulation Drying Oven

The nitrogen hot air circulation oven generates hot air through electric heating, which circulates within the sealed chamber while nitrogen is introduced to displace air, preventing material oxidation. It is used for drying and curing processes of oxygen-sensitive materials and is commonly employed in oxygen-free heating applications in industries such as chemical and electronic components.
Selection
When selecting, consider the material's temperature resistance range to match the heating temperature, determine the inner tank size based on the processing capacity, choose the nitrogen concentration control accuracy according to process requirements, confirm the equipment's external dimensions based on site conditions, check the fan power to ensure uniform hot air circulation, and verify that the power specifications meet the installation environment.

Temperature gradient control in high-temperature ovens during thermal resistance testing.
The heat resistance test simulates the performance of materials under high temperatures using a high-temperature oven, and the accuracy of its results is highly dependent on the uniformity of temperature inside the oven.

What are the differences between a vacuum oven and a conventional oven?
The main difference between a vacuum oven and a conventional oven lies in their working pressure. Conventional ovens operate at atmospheric pressure, heating through air convection, making them suitable for routine drying tasks. In contrast, vacuum ovens are evacuated to low pressure to reduce air presence, primarily relying on thermal radiation for heat transfer. This makes them ideal for processing heat-sensitive, oxidation-prone materials or those requiring thorough drying.
