Accessories for underwater pelletizing

The issue of water, water filtration, and water treatment plays an important role in the underwater pelletizing of plastic pellets. To meet the demands, MAAG offers appropriate additional equipment and accessories for underwater pelletizing systems. PURO® is a highly efficient and compact process water system, suitable as an accessory for almost all applications. The various temperature-controlled water systems convey and cool the pellets in a closed circuit from the cutting chamber to the dryer.
