Hexprotect AQUA: Hexagonal floating cover
Our hollow ball floating cover: Armor Ball
LIGHT FLOATING BALL COVER FOR FLEXIBLE APPLICATIONS
AWTT INC.’s Armor Ball® floating cover systems deliver superior performance for demanding liquid storage applications across municipal and industrial sectors. Our hollow ball covers are engineered specifically for wastewater treatment facilities, metal processing operations, petrochemical plants, leachate containment systems, and raw water reservoirs where thermal management and wildlife deterrence are critical requirements.
The innovative design achieves optimal surface coverage through precise ball deployment, creating an interlocking matrix that covers up to 91% of the liquid surface. This comprehensive coverage forms a sophisticated thermal barrier that leverages both the inherent insulation properties of the trapped air within each ball and the low thermal conductivity of our specialized plastic composition. While maintaining natural ventilation through interstitial spaces, the system significantly reduces heat loss, controls light penetration, minimizes evaporative losses, and effectively manages odor emissions. These engineered benefits make Armor Ball® the preferred solution for operations demanding reliable, long-term performance in challenging industrial environments.
The Armor Ball® floating cover system offers superior operational flexibility compared to traditional cover solutions. Its dynamic design allows unimpeded access for static equipment, moving components, and dipping mechanisms, as the individual spheres automatically redistribute around obstacles while maintaining comprehensive surface coverage. This self-adjusting capability is particularly valuable in applications such as clarifiers, where the balls automatically track changing liquid levels and reconfigure around moving equipment without manual intervention.
In addition to its operational advantages, the Armor Ball® system serves as a highly effective wildlife management solution. The complete surface coverage creates an unrecognizable water signature, significantly reducing attraction for waterfowl and terrestrial wildlife. This capability has earned Federal Aviation Administration (FAA) approval, leading to widespread adoption at airports globally for wildlife control in retention basins and treatment facilities.
Unlike conventional netting systems, the Armor Ball® cover demonstrates exceptional durability in harsh weather conditions. The robust construction withstands ice formation and snow loading without structural compromise, eliminating the need for additional support infrastructure and reducing long-term maintenance requirements.

Reinforced shell
Hexprotect AQUA are manufactured using high density polyethelene sourced from top tiers manufacturers. The thickness of the shell is between 40% and 120% thicket than competitor's products.

Technical specifications
Armor® Balls are made of virgin or recycled, high density polyethylene HDPE (FDA (3) and NSF approved HDPE resins available for special applications). The cover is pre ballasted, increasing its weight more than 260%, making it suitable for high wind applications. Furthermore, the proprietary features and manufacturing process ensures the cover floats with slightly more than 50% of its shell above water. Compared to other shade ball covers, the Armor® Ball cover is more durable and offers improved wind resistance. Installation remains extremely simple, and simply consists of unloading the product directly onto the liquid.
