SHIELD BALL

Coverhex Shield Ball hollow ball cover systems offer highly effective solutions to problematic liquid storage systems such as municipal and industrial wastewater, treatment processing plants, metal and petrochemical plants, leachate, airports, raw water reservoirs and other applications for heat retention and waterfowl deterrent.

High surface area coverage is achieved by placing a sufficient amount of balls on the surface of the liquid. The balls arrange themselves to provide coverage of up to 91%. The result is a thermal insulation barrier which combines the insulation factor of the air held in each ball with the poor heat conductivity of plastic. While the air pockets between the balls are not sealed, they also contribute to this insulation system, which dramatically reduces heat loss and light transfer. The cover also reduces liquid loss through evaporation and prevents odor problems.

The Shield Ball cover, contrary to standard covers, does not represent an obstacle to static, moving or dipping equipment. The balls can be easily pushed aside and the cover reforms itself as the basin and obstacles change configuration, as in a clarifier. In fact, the balls will keep up with liquid level, rising, lowering and restacking themselves as needed.

This heavy duty shade ball cover is also an effective wildlife deterrent. When entirely covered, the body of water becomes unattractive to waterfowl and other wildlife such as deer. They simply don’t recognize it as water. Our hollow plastic ball covers have been approved by the FAA and are used in airports worldwide,

Compared to netting, Shield Ball covers are not sensitive to ice or snow damage and do not require any kind of support.
