A technology company that has been deeply involved in laboratory environment control for 26 years is setting a new industry record with a temperature control accuracy of ±0.002℃. Nanjing Expansion Technology Co., Ltd. (hereinafter referred to as "Nanjing Expansion Technology") has developed a precision environmental control system that builds a "technological fortress" for strategic emerging industries such as chip manufacturing, aerospace, and biomedicine.

Walking into a class 100 cleanroom of a leading chip company, engineers are working in the "microclimate" created by the precision environmental control system. The temperature fluctuations here need to be controlled within ±0.005℃. This almost stringent environmental control is a key support for the nanochip photolithography process.

"Environmental control has become the 'second laboratory' of modern scientific research." The chief engineer of Nanjing Expansion Technology introduced that in the field of biomedicine, vaccine development requires a constant temperature environment of ±0.5℃ for 21 days; aerospace material testing requires humidity fluctuations to be precise to ±2%RH; and in the chip manufacturing process, the photolithography stage is core and critical. To ensure the stable operation of the photolithography machine, it needs to operate in an environment with extremely precise temperature and humidity fluctuations. Even slight changes in temperature and humidity can cause thermal expansion and contraction or changes in the physical properties of the optical and mechanical components inside the photolithography machine, thereby affecting the light propagation path, focusing accuracy, and the accuracy of mechanical movements, which play a decisive role in the quality and yield of chip manufacturing.

These "invisible battlefields" are the technological high grounds that enterprises continue to tackle. Nanjing Expansion Technology, with its keen market insight, has captured this demand and adheres to a customer-centric philosophy, investing heavily in the research and development of precision environmental control cabinets. The R&D team has gone through countless experiments and improvements, leveraging HVAC and automation advantages, from the initial design to overcoming one technical challenge after another.The "high-precision" experimental environment is no longer a "stumbling block" hindering scientific research.

Currently, the precision environmental control cabinets independently developed by Nanjing Expansion Technology can achieve cleanliness levels of class 100, class 10, and class 1, with temperature fluctuation values of ±0.1℃, ±0.05℃, ±0.01℃, and ±0.002℃ for precise environmental control. Since its launch, after layers of market selection, it has been applied in numerous research and production scenarios: the temperature stability of a global semiconductor leading enterprise's R&D environment reaches ±0.01℃; the temperature stability of a global communication equipment leading enterprise's R&D environment reaches ±0.005℃; the temperature stability of a national large scientific device laboratory reaches ±0.005℃... Nanjing Expansion Technology, with its outstanding precision environmental control technology, has been firmly chosen by top national research institutions and leading enterprises in related industries worldwide.

On this self-innovation industrial chain, environmental control technology acts as an "invisible guardian," building a solid foundation for scientific breakthroughs. The precision environmental control cabinet is just a microcosm of Nanjing Expansion Technology's technological innovation. Since its establishment in 1999, Nanjing Expansion Technology has been deeply involved in the field of laboratory construction, continuously expanding its business boundaries, providing one-stop solutions for special experimental environment engineering such as constant temperature and humidity, biological safety, clean purification, high-precision control, and laboratory animal facilities.It is reported that Nanjing Expansion Technology is continuously developing iterations, aiming for a new climb towards ±0.001℃ ultra-precision control.
