Double Membrane Gas Cover
Double Membrane Gas Covers are suitable for installation on concrete and steel tanks. The outer membrane acts as a weather protector while the inner membrane expands and retracts to store biogas. The outer membrane is inflated with an ATEX air blower providing the necessary stability to withstand wind and snow loads. The membranes are clamped to the tank wall by stainless steel brackets. A cord is welded into the outer edge of the membranes to further increase their resistence to becoming detached during high winds. A centre pole and straps support the inner membrane when not inflated by gas. A net construction is placed across the starps to promote the activity of desulphurisation bacteria.
The Double Membrane Gas Covers can be supplied with the following options:
