Biogas Agitators GDD – Gastight ceiling lead through

The GDD was designed for installation on the (concrete) top of a gas tight tank and enables the operator to retract and service a SUMA OPTIMIX mixer without having to drain the tank.

The system may be installed on solid concrete roofs, specially designed bridges and other structures capable of holding the combined weight of the gas tight housing and submersible mixer.
