The shutter damper helps prevent the hot water coil from freezing by regulating the airflow, ensuring efficient operation even in cold conditions. 

By preventing cold air from entering the building when the unit is not operating, the damper helps maintain indoor temperatures and reduces the need for additional heating.

With leakage of less than 1% of the local design airflow rate at the local maximum static pressure, the damper ensures effective airflow control.
