Covers
For water storage applications, maintaining the quality of stored water is essential. Various options for covering the silo are available. A cover helps reduce the likelihood of algae formation, evaporation, and contamination from leaves.
Tensioned anti-algae covers
Our tensioned anti-algae covers are constructed from 210 g. woven polypropylene, featuring reinforced edges and stainless steel eyelets. The cover is designed to be easily supported with PVC tubes. It is secured to the exterior of the tank using special hooks and nylon cord. The primary function of the anti-algae cover is to inhibit algae growth, as its name indicates. Additionally, it prevents contamination of the tank contents by small objects and reduces water evaporation. The woven material of the cover allows for water permeability.
The tensioned anti-algae covers are most effective for tanks with diameters up to approximately 9 metres. For larger diameters, we recommend the installation of a reinforcement ring within the upper ring, coupled with a central support system. Alternatively, our product range includes two types of floating covers that can be considered.
Floating anti-algae covers
ENPI AIRFLOAT
The ENPI Airfloat is a floating cover constructed from polypropylene, designed as an effective solution to address issues related to algae growth, contamination, and sunlight exposure. This cover has been specifically engineered for outdoor applications with larger diameters. Its installation process is highly efficient; there is no need for centre poles or reinforcement rings. The surface of the cover features small, air-filled bubbles that provide it with significant buoyancy. The top layer of the cover is white, which reflects UV rays and reduces water heating in areas with intense sunlight. The cover is UV-resistant, ensuring a prolonged lifespan and easy maintenance.
FLOATING ANTI-ALGAE COVER
The floating anti-algae cover is designed for tanks with a diameter larger than approximately 10 meters. The cover is made from woven polypropylene and includes long pockets that contain light PVC buoyancy tubes. This lightweight frame provides the cover with buoyancy while ensuring that the water surface is nearly covered. The closed structure of the cover helps protect against contamination and UV radiation, while allowing rainwater to pass through.
Steel roof
Our galvanised steel roof is a robust solution for covering NPI tanks and water silos. It protects drinking water and other liquids from contamination, evaporation, and all weather conditions.
The roof is easy to install with lightweight panels that link together to form a watertight seal. It includes two standard hatches for tank access and fits tanks up to 14.63 metres in diameter.
