Protecting Our Navy

As our Navy’s ships travel the world’s oceans, the earth’s ever present magnetic fields impart a unique magnetic signature on the ships. This unique magnetic signature is called permanent magnetism. In order to minimize the ship’s level of permanent magnetism, a specific process called magnetic silencing, also known as degaussing, must be followed. Magnetic Silencing Facilities (MSF) are used by submarines and surface vessels to complete this process. The introduction of controllable magnetic fields is what drives the entire operation. 

With over 50 years of experience in developing rectifier solutions, Dynapower proudly produces the high power rectifiers that generate these controllable magnetic fields. With both standard and custom options, we can power any of your magnetic silencing operations.
