Having a uniform temperature within the working chamber of the industrial oven ensures also a uniform resulting product. However, if you prefer to optimize the full potential of specifying a customized oven, it’s crucial that you know the two critical elements when it comes to obtaining a uniform product out of the oven. These are control sensitivity and temperature uniformity.
In essence, temperature uniformity refers to the spread of deviation between the highest and lowest points of temperature within the working chamber of the oven. It is affected by many factors such as product loading style, airflow pattern, air circulation, oven temperature, and load placement inside the oven. Incorrect levels or amounts of these factors can significantly impact temperature uniformity, and thus, the final results of the curing or drying process.
Take for example the case of processing a part using flat and solid shelves or racks inside the custom industrial oven. Using a vertical airflow pattern is the biggest error one can make because the air will only be blocked and can’t find its way back into the return duct. You have to keep in mind that the oven works by transferring the heat through air movement which means incorrect air flow will just disable the equipment to work as required. Thus, a full-horizontal airflow will be the best option to facilitate good airflow.
Lastly, control sensitivity, which refers to the ability of the oven to react to any changes in temperature at a given point in time during its operation. This factor requires you to be very mindful about deciding on which industrial oven to choose because a wrong control means an unresponsive oven. It will not be able to respond appropriately to the specific requirements of your application.
So, even if you achieve uniformity in temperature, the absence of correct control sensitivity will cause your oven to perform badly. This is the reason why these two parameters must go along together.
