PureBallast 3 solutions for fishing vessels and live fish carriers

No matter if you trawl, seine or fish by line, your focus is what matters for your catch – from the movements of the fish to the weather and currents that affect them. Retrofitting a ballast water treatment system is an added necessity, but it doesn’t have to be a headache. For nearly 20 years, we’ve been making it easy. Alfa Laval PureBallast 3 provides an optimal fit for fishing vessels and live fish carriers, but also for your time and budget.
