High performance wind resistant floating cover: Armor Ball Aqua 275
AWTT INC. Armor Balls® AQUA shade ball cover systems offer a simple and maintenance free solution to reduce heat loss, evaporation, algae growth and odors.
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 Armor Ball® AQUA ball cover is constructed of polyethylene and is 100mm (4 inches) in diameter, with a weight ranging from 120g to 275g (depending on the application). The sturdy construction combined with the ballasting element inside the ball allow each element to float with about 30% to 50% of the ball submerge, making the cover wind resistant and preventing the balls from being blown out of the pond. Its sturdy construction ensure it is very durable, totally maintenance free, with airtight seals to contain the ballasting material (proprietary manufacturing techniques are used). Special HDPE formulation and ultraviolet stabilizers protect from the degrading effect of sunlight.
The Armor Balls® AQUA ball cover barrier, 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.
Armor Balls® AQUA 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. Compared to netting, Armor Balls covers are not sensitive to ice or snow damage and do not require any kind of support.
Armor Ball® AQUA 275 is made of virgin or recycled, high density polyethylene HDPE. Armor Balls® AQUA(160‐275) are widely used for all external applications due to their particular resistance to freezing and high wind conditions. The degrading effects of sunlight are prevented with UV stabilizing additives.
HDPE is recommended for most applications including demineralized water and Chromic acid applications. FDA (3) and NSF approved HDPE resins available for special applications.
