In cutting-edge fields such as semiconductor manufacturing, precision optical inspection, and high-end metrology and calibration, the core equipment housed in cleanrooms demands an exceptionally stringent operating environment. Even minute temperature drifts, inadvertent humidity fluctuations, or subtle air disturbances can become critical factors that limit equipment performance. The independently developed by Jice (Nanjing) Technology Co., Ltd. High-Precision Environmental Control System UPECS (Ultra-Precision Environmental Control System) The high-precision environmental control system was specifically developed to address this challenge—it is not merely a temperature-control device, but rather a comprehensive environmental support framework built around the core equipment.

Through its independently developed millikelvin‑level precision environmental control technology, Jice has achieved extreme control capabilities: air temperature stability of ±0.002°C, humidity stability of ±0.1% RH, and cleanliness at ISO Class 1. These performance metrics are not theoretical projections under ideal laboratory conditions; rather, they represent engineering results rigorously validated through the delivery of numerous real‑world projects. It is precisely this level of precision that enables the high‑precision environmental control system UPECS to provide truly reliable operational support for critical equipment—such as semiconductor lithography tools and ultra‑precise measurement instruments—that are extremely sensitive to environmental influences.

The performance observed in real-world projects further validates the system‑level advantages of the high‑precision environmental control system, UPECS. After deployment at one customer site, air‑flow disturbance levels at different frequencies were reduced by 90%, 86%, and 80%, respectively. Once the system was operational, long‑term drift‑induced disturbances were also markedly suppressed, with the fluctuation range narrowing by approximately 50% and the standard deviation shrinking by 45%. Only when the environment stabilizes can the equipment’s inherent precision potential be fully realized.

JiCe’s ultra‑high‑precision environmental control system, UPECS, is available in no standard sizes. The team at JiCe (Nanjing) Technology Co., Ltd. customizes the design for each unit based on its actual dimensions, installation space, and site conditions, ensuring seamless integration with the customer’s equipment—without encroaching on valuable cleanroom floor space or compromising routine operation and maintenance. From chilled water supply to terminal air delivery, every stage features closed‑loop regulation, and the entire system’s quality remains fully controllable from design through to delivery.

JiCe (Nanjing) Technology Co., Ltd. operates an R&D and manufacturing facility in Nanjing. We welcome customers to visit our plant to validate the operational performance of our ultra‑precision environmental control system, UPECS, under real‑world conditions, and witness firsthand its exceptional capabilities in maintaining temperature and humidity stability and suppressing airflow disturbances. For enterprises and research institutions that demand the highest levels of precision, environmental control is not a peripheral feature—it is an integral part of their core competitiveness. JiCe’s ultra‑precision environmental control system, UPECS, is designed to ensure that the environment no longer serves as a limiting factor for accuracy.
