Evac Evolution system schematic


Specifically designed for superyachts, the Evac Evolution ballast water management system (BWMS), produced by Cathelco, is compact, reliable and completely chemical free.

The new system represents our continuing commitment to the luxury yacht sector based on over 50 years of experience in marine engineering.

The yacht BWMS equipment was developed in tandem with systems for commercial vessels. However, right from the beginning, we have kept the yacht market in mind and incorporated specific features – a smaller filter, shorter UV chamber and more compact ‘footprint’, to name just a few.

The Evac Evolution BWT system is in the final stages of achieving U.S. Coast Guard Type Approval which is likely be received before the end of 2018. In addition, it is anticipated that the system will attain IMO Approval to the revised G8 standard early next year.
