ENGARD control unit


A computer system developed by Alfa Laval. The system optimizes the central cooling operations on board a ship. It monitors the seawater temperature and heat load conditions in order to adjust the pump output to the actual operating conditions.

Without a system to regulate seawater pumps, central cooling systems waste energy as their pumps operate at full speed even when the heat load is reduced. ENGARD automatically regulates the motor in seawater pumps to meet the need for seawater.
