We offer a range of high quality innovative silo cover and gas storage solutions.
The Covertec double membrane roof is an innovative, premium-quality roof system for the biogas industry. The system comprises two separate membranes manufactured from polyester woven fabric, PVC-coated on both sides, with a minimum weight of 27 oz/yd² (900 g/m²) and a minimum tear resistance of 900 lbs per 2 in. (4,000 N per 5 cm). The double-layer assembly is designed to even out pressure fluctuations in the container while the hemispherical and rotunda shape serves to maximize storage capacity. At the same time, the domed surface protects the cover against external weather action, such as heavy snow loads in winter.
Covertec silo covers prevent water infiltration, thereby maintaining full storage capacity. They also excel by their high tear strength and UV stability. The low gas permeability reduces gas and ammonia emissions by over 95%. At the same time, the nitrogen content of the manure is retained.
Using the Flexcover Combi solution, an existing tipping trailer can be converted for use as a manure transport vehicle to move liquid manure/fermentation liquids to fields in the same way as a tanker. This is accomplished by removing the original trailer tailgate and installing the Combi system onto the tailgate fittings. Any complex installation is avoided as the entire module is supplied fully assembled, including the pump and storage bag. Hydraulic hoses for the pump and RotaCut need to be installed on just one occasion prior to the initial assembly, with subsequent connection to the tractor/trailer hydraulics or an auxiliary pump.
