Suitable for continuous operation
A hot air oven works on the principle of dry heat sterilization. Heat is generated by electric heaters and evenly distributed by a forced air circulation fan, ensuring uniform temperature throughout the chamber. It is widely used in laboratories, pharmaceuticals, research institutes, food, and industrial testing applications.
