Semi-closed Genafloat®

The Genafloat® from Genap is an innovative, floating cover for water reservoirs. Our Genafloat® is specifically designed to combine durability with effective protection against algae growth, evaporation, and wave action. This water covering system maximises the storage capacity of the water reservoir while maintaining water quality.

Application of the semi-closed Genafloat®

The semi-enclosed Genafloat® is made from a double-sided coated, open-weave fabric and conforms to the shape of the bottom of the reservoir. The Genafloat® is available in both open and semi-closed versions. For new construction projects, the semi-closed system is often preferred; this system offers extra protection against leaf debris by attaching to the slope.

Genap’s semi-closed Genafloat® not only provides effective protection against various forms of pollution but also contributes to the preservation of water quality. This makes it an ideal choice for modern water storage systems in the horticulture sector. This cover is also available with an anchoring system for floating solar panels.

Infa Techniek | Terneuzen, The Netherlands

Three water reservoirs with a semi-closed Genafloat®

On behalf of distributor Infa Techniek, Genap has installed three water reservoirs at the new greenhouse complex of Verenigde Groenten Tuinders (VGT) in Terneuzen. These reservoirs are equipped with semi-closed Genafloat® covers that protect the quality of the stored water against wave action, algae, and evaporation. With a total storage capacity of 90,000 m³, approximately 150,000 m² of greenhouse is supplied with water.

Horticoop | Wervershoof, The Netherlands

Water reservoirs with a semi-closed Genafloat®

The recent expansion of the greenhouses at the Zwinkels bell pepper nursery in Wervershoof led to an increased demand for clean water for cultivation. At the request of Horticoop, we were asked to find a suitable solution. The main goal was to maintain water quality and ensure a consistent water supply. In response, we installed semi-closed anti-algae covers on two water reservoirs, which have successfully contributed to achieving these goals.
