Traditional (Chemical and Pharmaceutical) System
Green Pharmaceutical Environmental System Solutions
Under the industry trend of “Green Pharmaceutical Manufacturing, Leading the Future,” the pharmaceutical industry is placing increasingly stringent demands on production environments. As medical standards continue to rise and public expectations for drug safety grow, temperature and humidity control, air cleanliness, and system energy efficiency in clean pharmaceutical environments have become critical factors in ensuring drug quality. As a core supporting system for pharmaceutical companies, air-conditioning systems directly impact the compliance, safety, and efficacy of drug production. SCHLEE, a leading enterprise in industrial environmental control, has long been deeply committed to meeting the specialized needs of the pharmaceutical industry. Through continuous technological research and innovation, we have developed comprehensive environmental system solutions that comply with GMP standards. We are dedicated to providing pharmaceutical companies with green, efficient, and reliable air-handling systems, helping them build high-standard cleanrooms that meet modern pharmaceutical manufacturing quality management regulations and offering robust technical support for the green and sustainable development of the pharmaceutical industry.
System Principle
The pharmaceutical cleanroom environment system employs a technical principle based on hierarchical control and multi-level safeguards. The system utilizes a three-stage filtration system—primary, secondary, and high-efficiency—to ensure that air cleanliness meets the requirements of ISO Class 5 to Class 8. In terms of temperature and humidity control, an advanced Direct Digital Control (DDC) system is adopted. High-precision sensors continuously monitor environmental parameters in real time and automatically adjust actuators such as chilled-water valves, heaters, and humidifiers, maintaining indoor temperature within the precise range of 18–26°C and relative humidity between 45% and 65%. The system innovatively incorporates an energy recovery device that uses a total heat exchanger to recover cold and heat from exhaust air, pre-treating the fresh-air load and significantly reducing system energy consumption. Meanwhile, to meet the differential-pressure control requirements for different clean zones, the system employs airflow-tracking technology to automatically maintain appropriate pressure gradients, thereby preventing cross-contamination. As for the chiller units, highly efficient magnetic-levitation variable-frequency technology is utilized, enabling automatic adjustment of cooling capacity according to load fluctuations and ensuring efficient operation even under partial-load conditions.
System advantages
In terms of energy efficiency, the system’s energy consumption is reduced by more than 30% compared to conventional systems thanks to the application of heat recovery technology and a variable-frequency control system, significantly lowering operational costs. In terms of reliability, the system features redundant design and an automatic backup mechanism, ensuring that temperature, humidity, and cleanliness levels in critical areas consistently meet standards. As for control accuracy, the system achieves temperature control within ±0.5℃ and humidity control within ±3%, fully complying with GMP regulatory requirements. The system’s modular design makes subsequent maintenance more convenient and also provides excellent scalability, enabling it to adapt to the needs of pharmaceutical companies’ production line upgrades and capacity expansions. Through an intelligent energy management platform, the system can monitor energy consumption data in real time and automatically generate operational reports, providing data support for enterprises’ refined management. Most importantly, the system’s green design throughout its entire lifecycle helps pharmaceutical companies achieve their energy-saving and emission-reduction goals, enhancing their social image and market competitiveness.
