Double Membrane Gas Holder WD68S

Grade 5 Customized Anti-Odor Type: Special structure, stringent-grade membrane material, reducing penetration or leakage by 99%, achieving odorless and tasteless performance, suitable for projects particularly sensitive to odors.
Although ultra-low permeability material + fully sealed welding process + active protection system (strict control of inner membrane height and pressure) are adopted, achieving 99.9% airtightness. However, the permeability inherent in flexible materials cannot be completely avoided. Over time, ppm-level微量渗透 can cause sulfur-containing media to yellow the gas holder and produce strong odors. Minor leakage leaves a serious impression and also fails to comply with national relevant standards. The fifth-generation double-membrane gas holder technology of Da Bai Qiu adopts the strategy of "dredging rather than blocking," developing an organized negative pressure odor isolation solution. It collects ppm-level微量渗透 in an organized manner, achieving an odorless, non-yellowing, and leak-free gas holder. Through multiple project practices, it has been proven effective and is now officially launched in the market.
