What is the purpose of a heating coil in an air handling system?

The purpose of a heating coil in an air handling system is mainly to increase the temperature of the air that passes through it.

Specifically, it helps to:

Provide warmth to the conditioned space. This is crucial in cold weather or when a specific temperature needs to be maintained.

Compensate for heat losses in the ductwork and the space being served.

Ensure a consistent and comfortable temperature is achieved throughout the area.

Allow for fine-tuning of the temperature output based on the requirements of the occupants or the process.

For example, in a commercial building during winter, the heating coil in the air handling system warms the incoming air before it is distributed to different rooms, keeping the occupants comfortable. It also helps to maintain a suitable temperature for various activities or processes that take place within the building. Without the heating coil, it would be difficult to effectively heat the space and meet the thermal demands.
