How air heating systems are chosen for industrial, domestic, and commercial purposes

 Air heating is a part and parcel of many industries. It is used in bakery, laundry, oil & gas, power, and other industries for different purposes. It all depends on the requisites of the industries. Customized designs are often used to serve the purpose. Air heating elements are generally designed and manufactured based on the specific requirements of an industry. From hospitality to heating big furnaces, air heaters are used as a part of the operations. Let us find out how the responsible team of engineers choose air heaters.

Things to look for in air heating systems

1.  Knowing the process

Engineers first calculate the amount of air to be heated and what temperature. The rate of heat transfer will determine the equipment and industry needs. The atmosphere inside a machine will also determine the rate of heat transfer. Hence, it is the prime factor to choose the right heating elements for the purpose.

2.   Convection

Another important factor to consider in the air heating process is whether the machine is using a steady airflow or depending on the convection current. It all depends on the airflow rate. A heating element will be chosen accordingly based on the amount of heat to be passed to raise the temperature of a column of air passing through the element. When the airflow is forced, the rate of heat transfer will be higher than what is required to heat a stagnant air column. Checking the rate of convection also becomes very necessary.

3.  Applications

The application in an industry will determine the type of air heating elements required. It depends on what process the heated air will serve. It can be used to maintain an ambient temperature inside a room or maybe needed for industrial processes such as calcining, melting, drying, etc.

4.   Performance of the heating elements

The performance of an air heater needs to be calibrated according to the need of an industry. Customized solutions are provided for meeting this particular need.

Final words

These are some of the considerations when air heating elements are chosen. Follow the parameters mentioned to get the best solution.

How to optimally use heaters for chemical processing

Immersion heaters are the most common choice of a chemical processing plant. Immersion heaters come in a huge variety of shapes and sizes which is best to function as chemical heating elements . All that a company needs to focus upon is what type of chemical heating elements they should select as this determines the final strategy to implement immersion heaters into their system. Since immersion heaters are used for many different industrial applications, one needs to be familiar with the best choice of chemical heating elements available in the market. Immersion heaters as the name says are put in the solvent that they heat up. The solvent could be molten metals or non-metals, gases, water, oil or any other chemical. Immersion heaters are highly energy efficient as they heat the liquid while releasing their energy but one needs to familiarise themselves on the different shapes and sizes, accessories, kilowatt ratings, voltages, terminations, sheath materials and the ...
