Easy Procedure to Maintain the Hot Air Oven Effectively

For hot air oven maintenance, you can read the following points mentioned below:


  • Maximum Heating Capacity and Operation Timer: 

Adhere to the specified maximum heating capacity and operation timer. Exceeding these limits can lead to potential damage to the hot air oven or compromise the accuracy of the results. Following the recommended parameters ensures safe and effective operation.

  • Close the chamber door properly:

Always ensure that the chamber doors are securely closed during the operation of the hot air oven. Proper closure helps maintain the desired temperature inside the chamber, prevents heat loss, and ensures the efficiency of the sterilization or testing process.

  • Clearance from Walls:

Allow at least one foot of clearance between the hot air oven and surrounding walls. This clearance ensures proper ventilation and prevents any potential interference with the oven's exhaust or cooling systems. It also minimizes the risk of heat buildup in the immediate vicinity.

  • Avoid liquid sample testing:

Never place liquid materials inside the heating chamber. This is because the Presto Group hot air oven has been specifically designed for dry heat applications. If you will put the liquid materials in the humidity chamber then it will compromise the integrity of the equipment. 

By following these maintenance guidelines helps ensure the safe, effective, and reliable operation of the hot air oven, extending its lifespan and maintaining the quality of experimental or sterilization processes. Contact us at +919210903903 or email us at info@prestogroup.com
