Cooling Control System for Marine Engines

Rotary motion electric actuators are in use for cooling systems of marine diesel engines. They control pure water temperatures to cool diesel engines, as well as 3-way valve apertures that maintain adequate sea-water temperatures for cooling air. For marine use, equipment must endure harsher conditions than those for onshore equipment so as to assure safe navigation of the vessels. Approval certificates of classification societies are granted for electric devices or equipment that can endure such conditions. The PRP Rotary Motion Electric Actuator has been accredited by Lloyd’s Register Marine classification, the certification of longest standing among the international classification societies.
