Contact Oven

Contact-type drying ovens transfer heat by direct contact between a hot plate and the bottom of the sample, allowing the sample to be heated and dried. They are used for rapid drying tests of coatings, inks, and paper, and can simulate the heating processes in actual production.
Selection
Select the hot plate size based on the sample thickness, determine the temperature control accuracy according to the material's temperature resistance range, choose ventilation functions in combination with the laboratory space, and consider heating speed and energy consumption with reference to daily testing volume.

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.
