Silo cover | GasTIGHT execution

A gastight silo roof is a cover for a silo, which is made completely gastight, virtually emission-free and also suitable as an after fermentation unit. This silo roof offers the solution for the cover obligation that applies in many European countries. Depending on your wishes, the silo cover can be fitted gastight on the inside or on top of the silo edge. This choice has an effect on the extent to which maintenance can be carried out on the cover and the silo. The Flexxocover gastight has been designed to ensure a maximum lifespan in all circumstances and is therefore extremly durable for our customers. We make this possible by choosing the best materials, by using tested components and by certified production and assembly. Ask our sales experts for more information! This product is also available in a gas-open execution.
