Topside and Dockside Chlorinators

Overview

Biofouling of shipboard seawater cooling systems can degrade the heat transfer performance of heat exchangers, cause flow restriction, and add significant downtime for system and component cleaning. SAIC and the Naval Research Laboratory developed the SAIC Topside Chlorinator/De-Chlorinator Ensemble (AN/TSQ-218 and AN/PSQ-11) to treat the auxiliary and main seawater systems on U.S. Navy submarines while in port.

Applications

The chlorinator is intended for use on SSN 688 and Trident Class submarines to service the Auxiliary Sea Water (ASW) heat exchangers. The unit was designed to function directly from the deck of a submarine or use shore power.

Features

SAIC's chlorinator produces a small amount of sodium hypochlorite from seawater that is injected into the seawater cooling system to prevent biological fouling.

Benefits

The Topside Chlorinator uses electrolytic chlorination to create the chlorine, which controls biofouling and greatly reduces the requirement for seawater system component cleaning. The below deck installed De-Chlorinator works in conjunction with the Topside Chlorinator to satisfy both federal and state regulations for the discharge of chlorine to aquatic environments.
