An underwater pelletiser that removes dirt and fine particles from process water is said to drastically reduce power usage in water filtration and cut overall pelletiser energy use by 10-17%, according to Nordson BKG. The Optigon water filtration system eliminates the need for a separate fines-removal sieve, which in standard systems requires a secondary, dedicated water pump. Instead, all filtration is provided by a Polygon drum filter, where the 70-micron screens are finer than the 150-micron screens used in standard systems. Driven by a small motor, the drum rotates within the water that is circulated in the pelletising system by the main process water pump. By eliminating the secondary pump, the Optigon water filtration system uses 1,440 KW/year (measured at 8,000 hours), as against 44,000 kW and 98,480 kW for the company's Opti-Line and Poly-Line systems, respectively. Other energy-saving measures available as optional include the insulation of the water system to prevent heat loss; and insulation of the die plate heating flanges, with energy savings of 30% compared with standard die plates.
