Hot Air Oven is a laboratory test equipment widely used for sterilization. It makes most favourable use of dry heat to cleanse. Presto is engaged in manufacturing and exporting superior quality Lab Hot Air Oven which is extensively demanded in laboratories for testing.
Presto’s Laboratory Hot Air Oven functions electrically; a fan is duly installed in the machine that ensures a uniform temperature inside the chamber. The ovens have quality insulation with top quality glass wool insulation, which is supplied to fulfil various industrial requirements.
Utilizing forced air circulation, hot air ovens are used in the laboratory to perform the effect of ageing on various properties of any type of materials.
Presto’s hot air oven is equipped with a double-walled chamber. The inside wall of the chamber is fabricated with heavy stainless steel, and the outside wall is made of mild steel duly powder coated. Impartial mineral glass wool insulation, which is incorporated within the walls ensures that the cabinet is well insulated.
The heaters are mounted in the ribs at the bottom of the machine and on the sides of the chamber. It is also equipped with an air circulation fan and a hot air blower that ensures constant temperature distribution.
A special port is installed in the chamber with adjustable openings that have been provided in the oven for introducing an external sensor or for change of air. The control panel of the machine is provided on the side of the main body to support better visual monitoring. Samples for testing can be placed on the S.S. trays, provided with the machine for comfortable storage of test specimens.

A hot air oven, also known as a convection oven, operates on the principle of convection heating. The main principle behind a hot air oven is the circulation of hot air inside the oven cavity to evenly distribute heat and cook the food.

Here's how the principle of a hot air oven works:
Heating Element: The oven is equipped with an electric heating element, typically located at the bottom or the back of the oven. This element produces heat when electricity passes through it.
Fan: A fan is installed in the oven to circulate the hot air. The fan helps distribute the heat evenly throughout the oven cavity, ensuring consistent cooking and preventing hot or cold spots.
Thermostat: The oven is equipped with a thermostat that allows the user to set and maintain the desired temperature. The thermostat regulates the heating element to maintain a constant temperature inside the oven.
Air Circulation: When the oven is turned on, the heating element begins to generate heat. The fan then circulates the heated air throughout the oven cavity. As the hot air moves around the food, it transfers heat energy to the food, promoting even cooking.
Exhaust Vent: Hot air ovens usually have an exhaust vent to allow moisture and steam to escape. This helps prevent the accumulation of moisture inside the oven, allowing the food to bake or roast properly.
Cooking Process: The heated air inside the oven cavity cooks the food by transferring heat to the surface of the food. The food absorbs this heat, which then travels to the interior of the food, cooking it evenly.
Hot air ovens are commonly used for baking, roasting, and cooking a variety of foods. The hot air oven principle, where heat is mainly generated from the top or bottom without air circulation. Presto is the best hot air oven seller in India. You can get a hot air oven price.
