3 MEMBRANE GASHOLDER
Three membrane constant-pressure gasholders are designed to store biogas made from the anaerobic digestion of organic waste and sludge.
They are manufactured with biogas resistant polyester reinforced PVC membranes seam welded by high frequency electronic machines.
The exclusive 3MASTER system is designed to form an upper air chamber that gives a pneumatic push on the biogas chamber, which keeps the biogas chamber at a prefixed and constant positive pressure. The two chambers are divided from each other by a double membrane layer that ensures complete safety against the formation of a dangerous air and gas mixture. The one-piece gas chamber can be made in the factory, or on site. Closed piece construction prevents gas losses through the anchor bolts that fix the cover to the ground.
MAIN FEATURES
High safety level
Ecomembrane’s PATENTED 3 membrane system negates any possibility of a gas and air explosive mix because the biogas chamber is completely divided from the air compensation chamber. Any possible leakage from the gas membrane will be directly pushed outside trough special fitting passages that allow the natural gas discharge.
Low Energy Consumption:
The compensation air blower only operates when the biogas is being used from the gasholder and switches off when the gasholder is filling. The air blower is controlled by a pressure sensor and an air valve is fitted to the air chamber and set to limit the maximum operating pressure ensuring constant pressure of the biogas throughout the filling and emptying cycle.
Long Life:
3MASTER gasholders are UV resistant and designed to withstand substantial wind and snow loadings. The internal membrane is biogas tight. Three membrane constant-pressure gasholders are designed to store biogas made from anaerobic digestion of organic waste and sludge. They are manufactured with biogas resistant polyester reinforced PVC membranes seam welded by high frequency electronic machines. The welding of the internal membrane is made adding an Eco-Safe layer of pure PVC that stops every porosity of the fibres to the biogas
Shape Variability:
It is possible to manufacture gasholders with either a ½ sphere or ¾ sphere shape. Big sizes and sites where high winds are expected then a ½ sphere gas holder would be recommended. Upon request we can design special shape gasholders with rectangular base.
