ECC, LLC

ECC has been the leader and most reliable manufacturer of hollow plastic balls used as floating covers.

 

Not just a ball but a solution to a problem for many Municipal Drinking Water applications, ECC provides not just a ball, but a solution to a problem.

 

 

Waterfowl fatalities and process fouling in municipal and industrial ponds can be prevented by covering ponds with a Floating Ball Cover system.

 

Not just a ball but a solution to a problem

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.
P1010067ECC 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.
Yet this barrier to the elements does not present an obstacle to product dipping or equipment moving through the liquid surface. The balls are pushed aside, but quickly re-form their cover as the equipment moves forward or products are lifted away from the tank. The balls will rise and fall with liquid level within storage tanks, and also provide a constant cover over liquids held in reservoirs with sloping sides. If the liquid level falls — causing the surface area to shrink — the balls simply stack in a double layer; they automatically spread themselves into a single layer again as the level rises.
