Focused on constructing ultra-clean rooms, creating high-purity research and production spaces with advanced technology

In fields such as biomedicine, electronic semiconductors, precision manufacturing, and food testing, cleanrooms serve as the core operational space. Their cleanliness, temperature and humidity control accuracy, and airflow stability directly determine product quality and the reliability of scientific research results. Nanjing Expansion Technology Co., Ltd. (hereinafter referred to as "Nanjing Expansion Technology") has been deeply engaged in the clean engineering field for more than ten years. With a profound understanding of cleanroom technical standards, independently developed core technology systems, and refined full-process services, it has become a leading enterprise in the domestic cleanroom construction sector, creating high-cleanliness spaces that meet international standards for over a thousand clients, supporting high-quality industry development.

Precision Customization: Creating adaptable cleanroom solutions centered on requirements

Different industries have significant differences in cleanroom requirements: the biomedicine field must meet GMP certification requirements, focusing on controlling microbial contamination; the electronic semiconductor industry has strict demands on dust particle size and electrostatic protection; food testing laboratories need to balance cleanliness and cross-contamination prevention. Nanjing Expansion Technology understands that a "one-size-fits-all" solution cannot meet professional needs, so it has established a service model of "in-depth requirement analysis + scenario-based solution design" to customize Exclusive cleanroom solutions .

At the project initiation stage, the company forms a special team composed of clean engineering designers, industry technical consultants, and equipment engineers to deeply engage with the client's production/research site. Through on-site surveys, requirement interviews, and benchmarking against industry standards, the core parameters of the cleanroom are defined (cleanliness levels from Class 100 to Class 100,000, temperature and humidity ranges with accuracy up to ±0.005℃/±1% RH, airflow organization forms such as vertical laminar flow, horizontal laminar flow, and turbulent flow). For example, in a cleanroom project for a biological vaccine company, the team innovatively designed a "fully enclosed negative pressure clean system + online sterilization device" tailored to the sterile requirements of vaccine production, optimizing the separation layout of personnel flow, logistics, and airflow to effectively avoid cross-contamination, ultimately helping the client successfully pass GMP certification.
 

To date, Nanjing Expansion Technology has completed cleanroom projects covering multiple fields including biomedicine, electronic information, precision manufacturing, and laboratories. The solution adaptation rate is 100%, and customer satisfaction exceeds 98%, fully demonstrating the company's professional strength in customized cleanroom design.

 

Technical Strength: Driven by innovation, building a solid foundation for cleanroom quality

The core competitiveness of cleanrooms lies in technology. Nanjing Expansion Technology always regards technology research and development as the core of its growth, forming a R&D team of more than 20 senior engineers. It has built a comprehensive technical system covering clean air treatment, airflow control, intelligent monitoring, and energy saving, ensuring the quality of cleanrooms.

In terms of clean air treatment technology, the company integrates primary, medium, high-efficiency (HEPA), and ultra-high-efficiency (ULPA) filtration systems, achieving a filtration efficiency of 99.999% for particles larger than 0.3μm. It is also equipped with ultraviolet sterilization modules, with a microbial removal rate exceeding 99.9%, meeting the air purification needs of cleanrooms at different cleanliness levels. In the field of airflow control, sensors monitor airflow speed and pressure difference in real time, automatically adjusting fan speed to ensure airflow stability while reducing energy consumption by more than 30%, far exceeding the industry average. In intelligent monitoring, the company developed the "Smart Laboratory Management System," which can collect parameters such as cleanliness, temperature and humidity, pressure difference, and VOC concentration in real time. When data anomalies occur, alarms are automatically triggered and pushed to management terminals, achieving 24-hour visualized control of cleanroom operation status.

Additionally, Nanjing Expansion Technology strictly follows ISO 14644-1 cleanroom standards, GB 50073-2013 "Cleanroom Design Code," and other authoritative domestic and international standards. It has established a four-level quality control system for cleanroom construction: "technical disclosure - process inspection - concealed work acceptance - completion testing." Each construction step is supervised on-site by professional engineers to ensure that all indicators meet 100% of the standards after completion. With strong technical capabilities, a Class 100 cleanroom project for a semiconductor company undertaken by the company was verified by a third-party testing agency to have cleanliness, particle count, and airflow uniformity indicators exceeding contract requirements, earning high praise from the client.

Full-chain Service: Professional assurance covering the entire cleanroom lifecycle

Nanjing Expansion Technology understands that cleanroom construction is not a "one-time build." Every stage from early planning to later operation and maintenance affects the client's long-term usage experience. Therefore, the company has built a full lifecycle service system of "early consultation - solution design - construction - acceptance certification - operation and maintenance training," providing clients with a "one-stop" cleanroom solution.

During the early consultation phase, the company offers services such as industry policy interpretation, clean level selection advice, and cost budget analysis to help clients avoid decision-making risks. During construction, a "progress report + on-site communication meeting" mechanism is implemented to keep clients informed of project progress in real time. At the acceptance stage, the company assists clients in connecting with third-party testing agencies and industry certification bodies (such as GMP, ISO) to ensure smooth certification of the cleanroom. After project delivery, operation training and equipment maintenance guidance are provided, along with a 24-hour emergency service team to promptly resolve issues such as filter replacement and equipment failure during cleanroom operation. Regular on-site inspections are conducted to extend the cleanroom's service life and ensure its long-term stable operation.

After delivering a cleanroom project for a biomedicine client, due to expanded production scale requiring partial renovation, the Nanjing Expansion Technology team responded within 48 hours, formulated a renovation plan, and completed construction without affecting the client's normal production, winning client trust through professional service. This "customer-centric" service philosophy is the confidence behind Nanjing Expansion Technology's continuous deep cultivation in the cleanroom field.
 

In the future, Nanjing Expansion Technology will continue to focus on cleanroom technology innovation and service upgrades, closely following industry development trends (such as nanometer-level clean technology in the semiconductor field and sterile isolation technology in biomedicine), continuously breaking through technical bottlenecks to create "high cleanliness, high stability, high intelligence, and low energy consumption" cleanrooms for more clients, helping them seize market opportunities in fierce competition and injecting stronger momentum into China's high-end manufacturing and scientific research innovation.
