Filters, strainers, sieves and baskets in all kind of applications as in sea chests or sea inlet strainers, but also hair filters or pre-filters. These strainers are used to prevent unwanted materials and solids to flow into the process of cooling systems. These particles can cause severe damage to precious machinery. Polyethylene or HDPE and polypropylene or PP are often chosen for their good resistance to chemicals and seawater.
Many fluids in several compositions can be filtered due to the good material properties, p.e. chemicals but also of seawater, river water, briny water, sewage, etc. Plastic is in most cases a very good replacement of steel variations, because of their excellent corrosion resistance in seawater applications. Furthermore, it is much lighter and cheaper than steel. Even bronze and cunifer cannot equal their properties. Depending on the particles to be filtered, the maximum allowable pressure loss, capacity and service frequency the largest possible filter surface will be calculated so that a remarkable efficient and light filter will be generated. This results in a very low-pressure loss and less service and downtime for the customer.
Because the filters are very low weight the cleaning of the strainers is an easier job. No lifting device is necessary because plastic is 10 x lighter than steel! The device can be spared and the job is done quicker. The strainers have a large filter area and are very service friendly because of the smooth surface and scratch-resistance of the filters. The result: an efficient removal of solids and unwanted materials out of fluids.
