Automatic Airflow Control

The PTAC Control System will automatically control the intake and exhaust fans in the engine room based on the pressure and temperature in the engine room and the combustion air needs of the vessel’s engines.

Manual Airflow Control

All fans may also be controlled manually within the engine room when the system is placed in Manual Mode. This allows the user to customize fan speeds and airflow direction to accommodate various needs.

Fire System Interface

The PTAC Control System will automatically shut down all fans upon discharge of the fire system. A switch provided by the fire system manufacturer provides the signal to the system for auto shutdown.
