Hexa-Cover® secure Australia a 73% reduction in water evaporation
Hexa-Cover® is widely used worldwide for controlling evaporation (and at the same time controlling algae as well as keeping unwanted waterfowls from landing on covered waters). The Government of Western Australia is one of our clients and we are proud to share the evaporation is reduced by 73%. Thus, a significant amount of water is secured.
Evaporation sounds harmless, but in most water systems it creates a chain of operational, environmental, and economic problems including:
- Reduced available volume in reservoirs, ponds, and tanks
- Increased reliance on make-up water (often costly or scarce)
- Particularly critical in arid regions and drought conditions
- Losses can reach meters of water per year in hot climates
At its core, evaporation happens when water molecules gain enough energy (heat + airflow) to escape from the surface into the air.
Hexa-Cover® works by interrupting the physical conditions required for this process.
- Physical barrier: covering the water surface
Hexa-Cover® achieves up to ~99% surface coverage. This dramatically reduces the exposed water surface area. Less exposed surface = fewer molecules can evaporate. This is the single biggest driver of the ~95% evaporation reduction. - Wind suppression at the surface
Wind is a major evaporation accelerator because it removes the humid boundary layer above water. The Hexa-Cover® elements create a rough, interlocking layer that breaks the wind flow and stabilizes the air just above the surface. - Solar shading (heat reduction)
Direct sunlight heats the water, what increases evaporation. The Hexa-Cover® elements block the solar radiation and thus, reduce heat absorption in the water body. Lower temperature = lower vapor pressure → less evaporation
