Multiple Tank Cover Options

BioEnergy storage solutions include the industry’s best cover options for digester applications.  The gas zone of a digester is the most corrosive area and requires appropriate design.

Along with this corrosiveness, there are many other factors (environmental, mixer loads, pressure, vacuums, ancillary equipment loads, etc.) that need to be considered in cover selection.  CST can design and engineer the right solution from the multiple cover types in its portfolio.

Externally Supported Roof:

Externally Supported Roof_CST BioEnergyThe most common roof design in the industry with a smooth internal roof surface and no rafters.  Used when moderate to high pressure or vacuum design limits are anticipated.  It is also preferred when there are heavy load conditions expected from mixers and/or other ancillary equipment is installed in the cover.

Knuckle Roof:

Dual Membrane Covers:

Membrane Gas Holders:
