Main Applications

RXH series hot air circulation ovens are widely used in pharmaceutical, food, chemical and other industries to heat, dry or dehumidify materials.

The machine works by using steam or electricity to heat air, which is then circulated to dry the material. Temperature differences within the chamber are minimal, ensuring uniform drying. Fresh air is constantly added and hot, humid air is exhausted during the drying process, maintaining the appropriate temperature within the chamber and ensuring a consistently dry drying process.
