Brief Introduction
For this double membrane gasholder, it's designed and manufactured by our company, so technical support, customized design, instructions on installation and other services can be provided according to your requirements. Flexible holder design and German advanced production technology are adopted to provide safe, reliable gasholder with excellent performance for customers.
Generally this independent double membrane gasholder is a 3/4 sphere, made of special processed polyester material and fixed on the cement foundation by rails. Divided into outer membrane, inner membrane and bottom membrane, the outer membrane is always pressurized to form the shape of gasholder and protect the inner membrane. As a result, rain, snow and wind have little impact on it. Then with the bottom membrane to function as foundation seal to realize the anti-corrosion, anti-leakage and easy installation, this double membrane gasholder is better than traditional wet gasholder both in performance and maintenance. Between the outer membrane and inner membrane, there's a variable-capacity airtight space to store biogas and other gases, such as carbon dioxide, oxygen etc.
Thanks to the high chemical resistance and mechanical strength of the imported materials, the double membrane gasholder satisfies the highest quality standards. With the ability of corrosion, microorganisms and ultraviolet rays resisting, the life time could be as long as 25 years.

Accessories
1) Air blower: It blows air into the space between the internal and external membranes of the gas holder to support the gas holder.
2) Check valve: It prevents air filled into the gas holder from flowing reversely.
3) Pressure gauge with electric contact: It measures the pressures of the internal and external membranes.
4) Liquid seal safety tank: It ensures automatic discharge of excess air in case of too high pressure between internal and external membranes of the gas holder.
5) Control cabinet: It automatically controls the startup of the air blower according to the pressure.
