Gravity Convection Oven

Gravity convection ovens generate hot air through bottom heating elements and utilize the natural convection principle that hot air is less dense than cold air, ensuring uniform temperature distribution inside the chamber. They are used for sample drying, curing, and aging tests, and are commonly employed in laboratory material processing.
Selection
Determine the temperature range and uniformity requirements based on sample characteristics; consider matching the chamber volume to the sample size; select corrosion-resistant materials to suit the testing environment; pay attention to heating rate and temperature control accuracy; ensure comprehensive safety protection features.

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.
