Cover Shade Balls

Euro-Matic Cover Shade Balls are an innovative and highly effective solution for covering large open liquid surfaces. They’re designed to reduce evaporation, suppress emissions, deter birds, and eliminate algae growth — all while enhancing environmental safety and lowering operational costs.

From wastewater and slurry lagoons to chemical tanks and airport ponds, Shade Balls form a durable, wind-stable floating cover that adapts naturally to changing liquid levels. They’re the smart, maintenance-free choice for challenging open-surface environments. (watch video)

Why Choose Shade Balls?

Each Shade Ball is precision-engineered to float efficiently, resist wind and weather, and create a dense, interlocking barrier over the liquid surface. This cover significantly reduces:

• Evaporation by up to 90%
• UV light penetration, almost eliminating algae growth
• Odour and fume emissions
• Bird activity and wildlife contamination
• Algae build-up, which can clog pumps and lead to costly downtime

By blocking sunlight and discouraging birds from landing, Shade Balls prevent algae blooms and nesting — two major sources of maintenance and contamination in industrial and environmental systems.
