In this era of surging data flows, data centers serve as the physical cornerstone of the digital world. The precise control of their 

internal environment directly impacts the stable pulse of global information. Among numerous environmental parameters, 

humidity—often overlooked by the public—is actually the lifeline sustaining the secure and efficient operation of data centers. 

Hydronic humidification technology, leveraging its unique natural physical principles and high energy efficiency, is increasingly 

becoming an indispensable component in modern data center environmental control systems. It achieves a delicate balance 

between anti-static protection, stable operation, and reduced energy consumption.

The core of hydronic humidification lies in utilizing the natural physical process of water molecule evaporation. As dry air flows 

over a humidified membrane made of specialized materials, water molecules absorb heat from the air and vaporize, uniformly 

and gently increasing humidity. This process avoids high-temperature boiling or ultrasonic vibration, thereby preventing issues 

like “white powder” contamination (mineral precipitation) or localized over-humidification common in traditional methods. 

It ensures pure, consistent humidification quality, perfectly aligning with data center equipment's stringent requirements for clean air.

Within data centers, densely packed servers, storage, and networking equipment form an invaluable array of electronics. 

Excessively dry environments (typically defined as relative humidity below 40%) create ideal conditions for static electricity buildup. 

Electrostatic discharge (ESD) can generate thousands of volts in an instant, sufficient to damage delicate integrated circuits. 

This leads to data corruption, degraded hardware performance, or even permanent physical damage—often with catastrophic 

consequences. By maintaining ambient humidity within the optimal range of 40%-60%, wet membrane humidification systems 

significantly enhance air conductivity. This allows static charges to dissipate steadily, preventing accumulation to hazardous levels 

and creating an invisible electrostatic shield for valuable information assets.

Beyond safety, wet-membrane humidification demonstrates exceptional advantages in enhancing data center energy efficiency 

and reducing total cost of ownership. Compared to electric (electrode) humidifiers that consume substantial power to boil water, 

or ultrasonic humidifiers that may generate fine particulate contamination, the evaporation process in wet-membrane systems is 

inherently low-energy. Primary power is used solely to drive fans circulating air through the humidification membrane. Its isenthalpic 

humidification characteristic provides a slight cooling effect on the air while humidifying. Under specific seasonal and operational 

conditions, this can moderately reduce the cooling load on precision air conditioning systems, achieving synergistic energy savings. 

Furthermore, the wet membrane humidification system features a relatively simple structure with few moving parts. It avoids 

high-temperature components and complex water treatment systems (when using purified water), significantly reducing failure 

rates and the complexity and cost of routine maintenance. Its modular design facilitates cleaning, replacement, and capacity 

adjustments, granting greater operational flexibility and manageability to data center maintenance.

Amidst the global push for sustainable development driven by the “dual carbon” goals, the green and low-carbon transformation 

of data centers has become inevitable. Wet membrane humidification technology perfectly aligns with this trend through its high 

efficiency, energy savings, stability, and low maintenance requirements. It not only safeguards core IT equipment through precise 

humidity control, enhancing data center reliability and availability, but also substantially contributes to reducing data center PUE 

values and carbon footprint by minimizing its own energy consumption and optimizing overall HVAC system efficiency.

In summary, wet membrane humidification technology is far more than a simple environmental adjustment tool. It serves as a silent 

yet highly efficient guardian within the precision environmental ecosystem of data centers. Leveraging natural physical principles, 

it strikes an optimal balance between preventing electrostatic hazards, ensuring stable equipment operation, and advancing green 

energy efficiency. As data centers continue to expand in scale and power density, wet membrane humidification technology will 

inevitably play an increasingly critical role in building safer, more efficient, and sustainable digital infrastructure, safeguarding the 

steady and far-reaching progress of the digital world.
