Main features:

The appearance tends to be perfectly spherical without any wrinkles

Stable pressure, low pressure fluctuation

Separate air intake and outlet

No embedded pressing plate is required

Pay attention to installation details


Membrane materials

Biogas special purpose membrane has flame retardant, anti-bacterial and anti-ultraviolet properties, and meets the following standards: the sunlight fastness conforms to DIN 54004 7 standard, the flame retardant performance conforms to DIN 4102 B1 design standard, the heat expansion and cold shrinkage resistant conforms to DIN53361 standard, the waterproof conforms to DIN 51635 standard, and the ductility meets DIN 53359 standard.


The outer membrane is coated with PVC/PVDF which has high strength and self-cleaning. The inner and bottom membrane have good air tightness and remains inert to the main components of biogas (CH4, H2S). Generally ranging of membrane strength is from 4000 N/5 cm to 9000 N/5 cm, can be calculated according to snow and wind load.


Controlling device

The explosion-proof blower is an important part of the double membrane gas holder. MONDES adopts the anti-corrosion and anti-explosion blower to adapt to the harsh site environment and ensure the durability of blower.

The storage volume monitoring device is another important part of double membrane gas holder. The biogas storage volume signal can be used for remote control. The biogas flare will automatically start when the biogas level is higher than 90%, the lower alarm will be given when the biogas level is lower than 20%, meanwhile, the gas appliances such as biogas booster fan and boiler will be closed.
