In the global transition toward renewable energy, the efficient management of biogas—produced from anaerobic digestion—is critical. Center Enamel provides industry-leading Double Membrane Gas Holders (often referred to as gas balloons) designed to offer safe, dynamic, and cost-effective storage for agricultural, municipal, and industrial biogas facilities.
With over 30 years of experience, Center Enamel combines advanced material science with precision engineering to deliver storage solutions that optimize gas production and ensure operational continuity.
The double membrane system is an intelligent, air-supported structure that eliminates the need for complex, heavy internal frameworks. It consists of two specialized, high-strength layers:
Inner Membrane: Acts as the primary, gas-tight chamber. Its flexibility allows it to expand and contract dynamically based on gas volume, managing fluctuations in production without the risk of over-pressurization.
Outer Membrane: A robust, dome-shaped shield. It is maintained under positive air pressure by a blower, acting as a protective barrier against weather, UV radiation, and mechanical impacts.
Inter-Membrane Cavity: The space between the layers is pressurized, ensuring the outer shell maintains its structural shape while the inner membrane remains protected and stable.
Dynamic Capacity: Our systems accommodate variable gas production levels seamlessly, ensuring a steady supply for energy conversion units.
Extreme Durability: Constructed from high-strength, UV-resistant technical fabrics, these balloons are engineered for long-term outdoor performance in diverse climates.
Sustainability & Odor Control: By providing an airtight, sealed environment, our balloons prevent methane emissions and effectively contain odors, supporting environmental compliance and community safety.
Energy Efficiency: The air-supported design significantly reduces the energy required to maintain pressure, lowering the total cost of ownership (TCO).
Center Enamel’s gas holders are currently utilized in projects spanning agriculture, wastewater management, and industrial processing. Our technology is scalable, fitting everything from localized farm-based digesters to large-scale municipal facilities.

A: The flexible nature of the double membrane system allows it to accommodate pressure changes naturally. Integrated pressure management features prevent the dangerous vacuum or over-pressure conditions that can occur in rigid, fixed-volume systems.
A: Minimal. Unlike rigid steel tanks that require ongoing painting, sandblasting, and corrosion protection, Center Enamel's membrane holders are made from chemically robust fabrics. Routine inspection is straightforward and significantly less labor-intensive.
A: Yes. While optimized for biogas from anaerobic digestion, our membrane technology is versatile and can be adapted for the storage of various industrial gases, provided the chemical compatibility is verified by our engineering team.
A: Absolutely. We offer bespoke engineering to match your digester size, gas production volume, and local environmental conditions (wind, snow loads, temperature).
