Intended for use in biogas plants with membrane closure digesters: this structure makes it possible to install mixers inside digesters and then remove them without losing gas.
The BST150 version is designed to house the CS150 service cabin with relative TBM mixer. The BST150F version is closed above with a plate that permits the fitting of dedicated structures for housing AF flow accelerators.
A skirt below the opening hatch makes it possible to isolate the well for the removal and installation of a mixer without losing gas and without having to lower the pressure inside the membrane dome.
The structure’s wall fixing arms are adjustable to adapt to different digester diameters. The lower struts are adjustable with hinges and spiders on the ends to simplify installation operations.
