New: sustainable filters with excellent seawater resistance


STC Trade is a company focused on sustainable innovations for shipbuilding and the marine industry that has created an environmentally-friendly alternative to the common metal filters.

Their solution is high-density polyethene (HDPE) filters and fibre-glass reinforced plastic castings. The high-density polyethene HDPE filters created by STC Trade are moulded from a naturally tough and resistant material that can withstand corrosion by seawater and external influences. This means that their lifespan is unlimited and as a result, the cost of ownership is much lower. Another benefit of the filters is their design – their lightweight feature enables them to be lifted out of the inlet strainer and cleaned easily by one person. The perforated plastic sheets have been developed under the brand name Perfoplast™.

Based in the Netherlands, STC Trade successfully introduced the HDPE filters in the Dutch superyacht industry in 2009 and has been the preferred supplier to many leading Dutch superyacht builders since. Over 700 filters are onboard various superyachts around the world, including the new plastic filters for bilge water.

Thanks to their versatility, the HDPE filters can be delivered both during the new building phase, during a refit or as a replacement. Besides the HDPE filter elements the strainer housings are designed and delivered in GRP of HDPE. The former are also certified under IMO Regulations. In 2015 STC Trade began introducing their products into the commercial shipping sector to further their bid to preserve the environment. IHC and Damen shipyards have been applying filters from STC Trade in their inlet strainers as a large number of Dutch yacht builders do!

Biggest filter ever
This month STC Trade has designed and made its largest filter ever. The tailor-made filter is for a Greek customer and has a height of 1225 mm, a diameter of 900 mm and an inlet of 613 mm. The filter is now transported to South Korea where it will be installed in the ship.
