Davis :: Sea Water Injected (SWI) Eductor/Diffuser

Scalable to fit any size uptake.

Can be configured to activate only in threat situations. Delivers Level 3 suppression in normal conditions.

Custom nozzle selection and placement ensures efficient use of sea water and uniform plume temperatures.

Level IV IR suppression.

Highest performance IR suppressor available on the market.

Benefits of the SWI Eductor/Diffuser:

The SWI system is controlled by the Onboard Signature Manager (OSM), which interfaces with the ship machinery control system in order to control the flow of water as a function of the engine operating state.

The SWI system mounts directly to the uptake and is located immediately upstream of the Eductor/Diffuser nozzle. The system uses an array of atomizing nozzles to inject a fine mist into the exhaust stream. As the water evaporates, heat is transferred from the hot exhaust gas into the water vapor, resulting in a lower average gas temperature. The location and size of the nozzles is custom designed to the size of the uptake in order to ensure that the system uses water efficiently and the plume is uniformly cooled.

The Sea Water Injection (SWI) system can be used in conjunction with an Eductor/Diffuser in order to achieve plume temperatures below 150 degrees C. As with the Eductor/Diffuser, uptake metal temperatures are cooled to less than 25 degrees C above ambient.
