2MASTER

2 MEMBRANE  GASHOLDER

Two 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.

The 2MASTER system is made with a single upper membrane, pressurized by an air fan 24 hours a day to give a pneumatic push on the inner biogas chamber, keeping the biogas chamber at a prefixed and constant positive pressure. 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 or tank.

MAIN FEATURES

High Storage and Gas Flow Rate:

The 2MASTER system is suggested for use in all cases where storage volume is greater than 3000m³. The lighter weight of the 2 membrane allows larger gas holders to be constructed. The 2 membrane system is also proposed where high and variable gas flow rates are expected.

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.
