Human perception and exploration of the external world is a continuous journey from the unknown to the known and from the unfamiliar to the familiar. The same principle applies to human understanding of the internal biological world. From genes and cells to tissues and organs, medical science seeks to understand normal physiological states. When abnormalities arise, determining how to correct them drives research and innovation in disease treatment and pharmaceutical manufacturing.

As an advanced high-tech sector, biopharmaceuticals represent modern bioengineering rooted in genetic engineering. For more than 30 years, biopharmaceutical technology development has created expansive opportunities across the medical and pharmaceutical industries, significantly improving human health and quality of life. With high added value and vast market potential, biopharmaceuticals are recognized globally as a critical technology and a key strategic emerging industry for 21st-century scientific and economic development.

However, significant challenges and market opportunities coexist. Ensuring safe, efficient, and compliant manufacturing of biopharmaceutical products remains a fundamental objective for biopharmaceutical enterprises, particularly amid fierce market competition and concentrated product varieties. In this environment, deploying advanced cleanroom enclosure systems to maintain stringent cleanliness levels, optimize product quality, and ensure biosafety throughout the production process has become a top operational priority.

Founded in 1993, 3SBio Group is an integrated biopharmaceutical enterprise spanning R&D, production, and sales. It boasts a comprehensive pipeline of therapeutic products covering oncology, autoimmunity, nephrology, metabolism, and dermatology. In this facility project, essential clean areas such as the aseptic material room, aseptic filter room, B-level corridor, and B-level dressing room were constructed within the production workshop.

Endure® Cleanroom Panel

Disinfecting environment · Excellent performance

In clean room B-level areas, the maximum allowable count of suspended particles is ≧0.5µm (micrometers), and planktonic bacteria must be <1cfu/m³ (1 colony per cubic meter). To satisfy these standards, biological environment systems require regular disinfection to control airborne microbial contamination from suspended microorganisms. However, high concentrations of hydrogen peroxide can corrode conventional color steel plates, leading to surface blistering on the corroded panels.

In order to avoid this problem, Cnsterilezoom endure^® panels serve as specialized steel plates for the pharmaceutical industry. Key performance benefits include superior resistance to VHP disinfection, exceptional wear resistance, easy cleaning, safety, and environmental protection.

Matte shell white finish with elegant aesthetics

Endure^® features an attractive design with minimal color variance. The color difference of the same batch is △E＜0.3, and the color difference of different batches is △E＜0.5. Finished in shell white with a matte surface, it delivers superior visual appeal, a smooth uniform texture, and a glossiness of 8-10.

Hollow Return Air

Beyond the strict cleanliness requirements of biological product workshops, clean room facility design must remain standardized, ensuring aesthetic and practical room layouts while optimizing space utilization. Conventional clean room facilities typically rely on traditional return air columns for air handling, which occupy substantial floor space and disrupt aesthetic appeal. To effectively resolve these operational challenges, Cnsterilezoom provides a 100mm hollow return air unit module that completely replaces traditional return air columns and 100 thick hollow shrapnel walls in dressing and shoe-take-off buffer rooms, greatly optimizing overall space utilization.

To rigorously satisfy modern clean room GMP compliance standards, Cnsterilezoom's advanced 100mm hollow return air wall incorporates modular customization and utilizes leading international drilling technology. Additionally, detachable return air outlet engineering simplifies ongoing maintenance, cleaning, and disinfection. Featuring factory prefabrication and rapid on-site assembly, it ensures convenient, fast installation.

3SBio Group has continually dedicated itself to resolving clinical medication challenges for patients, conquering complex disease obstacles, and improving patient quality of life with high-quality therapies for human health. As an established professional service provider in clean room engineering systems, Cnsterilezoom consistently drives product innovation across cleanroom building enclosure systems, delivering proprietary patented solutions that address critical industry pain points for 3SBio.

Delivering superior product quality to ensure complete peace of mind, confidence, and enduring success for every client.
