Hot Air Oven

Dry Heat sterilizer/Hot Air Oven/Gravity Convection Oven


You demand and we design oven for your application in research, laboratories, Universities, and Hospitals. Hot air ovens are designed for baking, drying & de-pyrogenation in the laboratory, Microbiology, bio-medical, Pharmaceuticals & Textile Industries. These places need a fast heating rate with constant temperature and our oven can attain 300 degrees Celsius temperature within a few minutes of starting the oven.

Dry heating is one of the methods of sterilization and ovens are known as dry heat sterilizers. Dry heat sterilization works at 171 degrees Celsius to 224 degrees Celsius. Sterilization has three methods: one is steam sterilization, the second one is H2O2 sterilization or ethylene oxide sterilization, & third is the last method of sterilization is dry heat sterilization requires high temperature. Dry heat sterilization requires a Hot Air Oven for killing microorganisms at high-temperature ranges from 171 to 224 degrees Celsius.

We are the leading manufacturer, supplier, exporter and distributor of Hot Air Oven in India. Our Hot air ovens are rugged in construction with accurate and uniform temperature. Yatherm manufacture Hot air oven up to 400 degrees Celsius working temperature. Our Hot air ovens consist of round shape air heaters with imported motor for circulation of fan.

Yatherm Hot air ovens are suitable for operation within the range of ambient to 300°C and readability 0.00°C with an accuracy of +/-1% only. PID controller has timer up to 9999 minutes and an alarm facility for high and low temperatures. Temperature is uniform inside the Chamber because of the air circulatory fan. We also offer a safety thermostat of temperature for our hot air oven.


Hot Air Oven Construction:

Double-walled and triple-walled construction with inner SS 304/316 and outer construction of Mild Steel powder coated. Double-walled hot air ovens are insulated with Mineral wool insulation instead of glass wool insulation for zero skin temperature. Oven Chamber consists of adjustable SS 304 trays for keeping samples and glassware. Air circulatory fan is covered by mesh type steel cover for the safety of the user. Yatherm ovens are mounted on heavy castor wheels with two lockable wheels and two free movable wheels.



Doors are designed in double-walled construction where inner door made up of complete SS 304 and outer MS powder coated with 60 mm mineral wool insulation in between the walls. Doors are equipped with high-quality heavy hinges and door lock handle facility to avoid intervention. Yatherm also offers toughened glass for easy view of samples on customer’s request.


Heating Elements:

For uniform and efficient heating inside the chamber, we provide air heaters instead of nichrome wires and heaters. ISI mark air heaters come in u shape and ring shape which works only with a circulatory fan. Fin type air heaters provide fast heating at a high RAMP rate.
