Model TGZ - Non-Pressurized Gas Storage System


EnvironTec's TGZ non-pressurized gas holder consists of a prefabricated metal silo made of corrugated steel segments with lateral stiffeners attached to it and a conical roof. Inside it, a tight, high quality, UV-and-fungus-resistant membrane treated with flame retardant (DIN 4102 B1), is connected to the top and the bottom of the silo structure using AISI316Ti flanges, avoiding the membrane to be in contact with the silo walls. Additionally, a protective floor matt is laid on top of the concrete foundation in order to avoid damages on the membrane. The membrane will inflate and deflate as gas flow in and out respectively. Hydraulic pressure-security devices, a mechanical pressure-relief valve as well as an optical fill level indicator and vacuum monitoring ensures and full of continuous monitoring and control of the membrane.
