- Gas hood and support flange are on top of one another parallel and level, form-fit and non-displaceable. They transfer the dynamic forces and vibrations of the mixer directly to the substructure.
- The gas hood with the mixer can be uninstalled at any time. The impeller clearance in the draft tube pipe remains unchanged during the re-installation. It does not require any readjustment.
- Defined sealing forces ensure reliable effect and a long life of the gas hood seal.
Gas Hoods
*Gas hoods are calculated individually for each project.

Gas hoods are needed to cover larger openings on the digester tank head with a diameter of up to 3 meter. They take up the mixer while transferring all forces and moments to the substructure of the digester tank. Gas hoods are designed individually for the respective mixer type and digester tank head. All assembly parts are arranged customer-specific: gas extraction dome, over- and under pressure safety relief valve, foam fighting, inspection glasses, measuring sensors, etc.
The Träxler gas hood is equipped with strong mechanically machined flanges in the transition from gas hood to tank frame, curved discs are welded. An O-ring is used as gas-proof seal between gas hood and frame. This O-ring is inserted in a mechanically processed groove. The reinforcement of the ribs is calculated by using a load analysis per FEM Finite Element Method.
