Covertec Silo cover with gas-tight lung

Short Summary

The standard silo cover with gas-tight lung is a gas-tight model incorporating a sheet „lung“ for the storage of gas produced by any type of organic substrate. The cover is clamped to the internal face of the silo to produce a gas-tight seal. With the premium-grade model, the gas-tight seal is positioned on the top edge of the container, thus allowing the cover to be removed even when the silo is full.
