Natural Convection Chamber

The natural convection oven uses the cyclic flow of air rising when heated and sinking when cooled to conduct constant temperature aging tests on samples. The chamber is heated by heating elements without the need for fans for forced convection, simulating a natural ventilation environment. It is used for evaluating the thermal stability and observing the weather resistance of materials such as coatings and plastics, commonly found in laboratory aging experiments.
Selection
When selecting a natural convection oven, consider the temperature range and uniformity, match the chamber volume with the sample size, and ensure temperature control accuracy meets standard requirements. Pay attention to the balance between heating power and heating rate, and select a chamber material that is corrosion-resistant. Confirm that safety protection functions are complete, the operation interface is user-friendly, and maintenance is convenient.

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.
