PureBallast 3 solutions for general cargo and multipurpose vessels

When your vessel is for merchant trade or contract work, your first concern is what it carries – bulk or break bulk, liquid cargo or dry goods, or things like people and equipment. 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 general cargo vessels or multipurpose vessels (MPP/MPV), but also for your time and budget.
