The Application of NA200 in Energy-Saving, Constant-Temperature, and Dehumidification Systems
In many industrial production processes, establishing a stable, constant-temperature dehumidification system is an essential and critical step to ensure smooth operations. While constant-temperature control technology is now relatively mature, achieving effective dehumidification under such conditions remains a complex task in terms of implementation. By leveraging the NA200 series PLC introduced by Nanda Aotuo Company, we can efficiently realize control for energy-saving, constant-temperature dehumidification systems.

The Application of NA200 in Constant-Pressure Water Supply Systems for Residential Communities
As people increasingly demand higher quality in water supply and drinking water, the variable-frequency constant-pressure water supply method has emerged. This innovative approach not only effectively addresses the issue of secondary water contamination caused by traditional rooftop tank systems but also optimizes the operation of water pumps—eliminating the inefficiencies associated with adjusting pump speed combined with outlet valve control for regulating water flow and pressure. By doing so, it significantly reduces energy waste that typically occurs due to resistance in the outlet valve, while simultaneously providing excellent protection for the pumps and achieving substantial energy savings. Today, variable-frequency constant-pressure water supply systems are widely adopted in urban municipal water networks, residential community domestic and fire-fighting water systems, building central air-conditioning cooling water circulation systems, and industrial equipment cleaning systems.

NA400 PLC Engineering Case Study — Wastewater Treatment System
Relevant data shows that the United States has, on average, one wastewater treatment plant per 10,000 people, while the UK and Germany each have one plant for every 7,000 to 8,000 residents. In contrast, China only has one wastewater treatment plant for every 1.5 million people. This highlights the urgent need for wastewater treatment in China, while the market for wastewater treatment is also witnessing a vibrant and rapidly growing landscape.

Application of NA400 in Water Treatment
As the new sub-center of Nanjing's urban area, XX District has entered a period of rapid economic growth and urban development. However, along with this swift economic expansion, environmental issues in the district have become increasingly prominent. Currently, industrial wastewater from industrial parks and domestic sewage are largely discharged into water bodies without proper treatment, severely polluting surface water and groundwater systems, thereby affecting people's daily lives, health, and ultimately hindering the city's sustainable growth. At the same time, public demand for environmental protection continues to rise. Therefore, constructing a wastewater treatment plant has now become an urgent priority.

Pump Station Solution Based on NA400 PLC
As a key facility in water conservancy construction and management projects, pump stations play a vital role in urban drainage, flood prevention, water diversion, and supply. Since the 1990s, with advancements in IT technology and the vigorous development of the water conservancy sector, the level of automation in pump station operations has steadily improved. This has led to significant enhancements in both pump station technology and management practices, paving the way for the evolution toward unmanned pump station monitoring and management systems overseas—resulting in notable gains in efficiency while reducing manpower. Throughout this transformative process, pump station computer monitoring systems have become indispensable. Today's advanced monitoring systems enable comprehensive, centralized data collection across the entire pump station, along with automatic control of primary and auxiliary equipment, remote control and adjustment capabilities, and real-time information transmission—all critical features that drive smarter, more efficient operations.

Oil Pumping Unit RTU Data Acquisition Solution
The beam pumping unit is the abbreviated term for the beam-type pumping unit—deep-well pump oil production system, commonly known as the "nodding donkey" (due to its "donkey head" that continuously moves up and down during operation, resembling a person bowing). It is one of the most classic and widely used surface oil extraction devices in the petroleum industry.
