Now in its third generation, Alfa Laval PureBallast leads the way in ballast water treatment performance. With the introduction of Alfa Laval PureBallast 3.1 Compact Flex to the PureBallast family of systems, it also leads the way in minimizing footprint and installation costs.

Available space comes at a premium on any vessel. This is especially true when retrofitting major equipment such as a ballast water treatment system, which in most cases was never considered in the vessel design. On newbuilds as well, it can be difficult to incorporate a treatment system into the already cramped engine room.

Alfa Laval PureBallast 3.1 Compact Flex, a new PureBallast system based on loose components, is the answer to space and flexibility needs. Available for flows of 32–1000 m3/h, it packs the leading ballast water treatment technology into a footprint up to 20% smaller than that of PureBallast 3.1 – the smallest on the market. Likewise, it reduces installation costs by up to 10%, thanks to a plug-and-play concept for quick and easy connection.

“Alfa Laval PureBallast 3.1 Compact Flex is economical, both in its use of space and in its installation,” says Anders Lindmark, Head of Alfa Laval PureBallast. “As a result, it removes headaches for both ship owners and shipyards. It’s an ideal choice for the vast majority of vessels, combining the smallest possible footprint with superior performance in the widest range of conditions.”

Available now, Alfa Laval PureBallast 3.1 Compact Flex joins the existing PureBallast family of ballast water treatment systems adapted to different customer needs. PureBallast 3.1 handles high flows and special requirements, while PureBallast 3.1 Compact offers a skid-mounted option. These systems have U.S. Coast guard type approval, which is also pending for PureBallast 3.1 Compact Flex. All three PureBallast 3.1 systems provide the same superior performance in fresh, brackish and marine water, including full-flow operation in IMO-regulated waters where the UV transmittance is as low as 42%.
