Armor Balls® Cover: 4 Inches Thick Shell Hollow Plastic Shade Ball Cover
AWTT INC. Armor 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. Our Armor Balls are not just a product; they’re your water’s shield, providing an innovative layer of protection for your reservoirs, ponds, and tanks.
Our AWTT floating covers offer a versatile solution for water maintenance needs. They help prevent algae growth, reduce water loss through evaporation, control unpleasant smells, and protect your water. Plus, the smart design allows rain and melting snow to pass through without harming the cover.
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 floating ball cover also reduces liquid loss through evaporation and prevents odor problems. By covering your water body with our designed Armor Balls, you reduce evaporation, deter wildlife contamination, and maintain cleaner water—all while saving on maintenance costs and conserving precious resources.
These lightweight yet durable spheres are engineered for maximum coverage, forming a barrier that outsmarts natural elements and preserves your water quality. Practical, adaptable, and environmentally friendly, these evaporation balls are a simple solution to complex problems plaguing individual and industrial water users alike.
The Armor Balls® 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,
