Double membrane gas holder is designed and produced by ZHAOYANG.

According to different customer requirements, we can provide technical research and development, customized, installation guidance, and other services. With professional production equipment, it produces gas holders with excellent performance.

There are two types of dual membrane flexible gas holders, integrated gas holders and independent gas holder.

The structure of the double membrane biogas storage gas holder is simple and requires no excessive maintenance. The membrane materials are made of corrosion-resistant and environmentally friendly special composite materials. Mainly made of high-strength tensile fiber, airtight anti-corrosion coating. Surface coating (Pvdf) composition. It has anti-corrosion, anti-aging, anti microbial and UV functions, and the fire rating has reached European standards. At the same time, the outer film has self-cleaning function.

The integrated gas holder is composed of a bottom membrane, an inner membrane, an outer membrane, and some control equipment and auxiliary materials; An independent gas holder consists of an inner membrane, an outer membrane, and some control equipment and auxiliary materials.

Integrated gas holder

The shape is mostly hemispherical or small, and it is used in connection with assembled or welded tanks, cement tanks, and so on. Form a whole project. The construction is simple, easy to install and maintain, and the entire system is easy to manage and control.

Independent double membrane gas holder

The outer shape is a 3/4 sphere or hemispherical body, fixed by steel rails on a cement base, and the main body is made of specially processed polyester material. The membrane body consists of an outer membrane, an inner membrane, a bottom membrane, and accessory equipment, all in accordance with relevant German product standards. An airtight space with variable capacity is formed between the inner membrane and the bottom membrane for storing biogas. The outer membrane forms the spherical shape of the storage cabinet, serving as a pressure space for protecting the inner membrane and forming a compressed inner membrane. It has the functions of preventing ultraviolet rays and protecting the inner membrane, and has self-cleaning functions.
