Alveolar Midnight 400-micron bubble cover

Alveolar technology

• The DEL Premium Alveolar cover is the result of 100% CF group R&D technology. It is a bubble cover made of 550 microns polyethylene with alveolar technology. It is manufactured with a welded edged finish around the entire perimeter for a very aesthetic appearance and good resistance over time.
• The alveolar cover is adjusted to the size of the pool to block over 99%* of evaporation, which saves water: for a 4.00 x 8.00 m pool, losses are limited to around 180 litres of the 200 litres evaporated in a day with 2 hours of swimming. It also saves energy: the phenomenon of evaporation drives to cool the water.
• The DEL Premium Alveolar cover has solar heating capabilities for free and clean energy as well as insulating qualities to limit heat loss: +7%* vs Geobubble 500?m. This performance is due to significantly reduced thermal bridges (-19% compared to Geobubble bubbles and -39% compared to conventional round bubbles).
• The 2 models protect the water from debris and other pollution, reducing the consumption of treatment products and filtration time. The high opacity of the black model stops the light that causes photosynthesis and algae growth. This significantly reduces the consumption of chemical products.
• The patented shape of the alveolar bubbles associated with a maximised PE film offer a long life time to the alveolar covers.
