The Evap-Cap is a patented floating evaporation cover made from light impervious polyethylene. The black bubble underside provides flotation and stops light penetration, while the white upper surface deflects the heat from the sun. Both layers are UV stabilised and designed to reduce evaporation to an absolute minimum.

Bartlett's unique 'on the water' installtion means you do not need to empty your dam and can cover when at capacity, allowing water saving benefits from day one.

With a 5 year warranty, the Bartlett Evap-Cap evaporation cover ensures:

• Up to 95% reduction of evaporation
• Reduction of algal growth
• Improved water quality
• Full retention of rainfall
• Reduction of salt build up
