Plastic Hollow Balls

For many industrial applications, ECC provides not just a ball, but a solution to a problem. Most of our successful installations have resulted from working closely with customers, sharing our ideas and experience and tailoring a solution to meet their specific requirements. ECC floating ball blankets provide highly effective solutions to difficult liquid storage problems in industries including Processing, Petrochemical and Metal Treatment. By placing a sufficient quantity of hollow plastic balls onto the surface of a liquid, the balls automatically arrange themselves into a close packed formation over 91% of the surface area. This high surface coverage provides an extremely effective barrier and significantly reduces the mass and heat transfer mechanisms operating between the liquid and surrounding environment. The hollow plastic balls that form a floating cover for ponds, tanks, lagoons, and other basins. The balls are of course hollow and full of air. And the plastic balls offer very low heat conductivity. Together, these properties result in a very effective thermal insulation barrier. The air pockets between the balls -- although not sealed -- also contribute to this cellular insulation system, dramatically reducing heat loss. The barrier works both ways: the low liquid surface area exposed to atmosphere dramatically reduces liquid loss through evaporation and odor release to the atmosphere. It also prevents surface absorption of oxygen. Available in PVDF, PP, and HDPE in sizes ranging from 10 mm to 150 mm.
