New Release: M20H Pressure Transmitter for Liquid Cooling CDU Systems

With the rapid development of large-scale AI models, high-performance computing, and data center infrastructure, power consumption of chip continues to rise; consequently, traditional air-cooling methods are increasingly struggling to meet the heat dissipation demands of high-density computing. Liquid cooling technology is emerging as a key development direction for next-generation data centers.

Among these technologies, direct-to-chip cooling—where coolant makes direct contact with heat-generating modules (such as CPUs and GPUs) via cold plates—is being widely adopted in AI servers, GPU clusters, and high-performance computing environments, thanks to its superior heat dissipation efficiency, lower energy consumption, and strong compatibility with existing server architectures.

Challenges

Within the liquid cooling system, the CDU (Coolant Distribution Unit) performs critical functions such as coolant circulation, pressure regulation, and heat exchange. It offers advantages such as precision cooling, compatibility with existing designs, and maintenance procedures similar to those of traditional systems, earning it the reputation as the "heart" of the liquid cooling system. Pressure parameters—such as supply and return water pressures and pump operating pressures—serve as the vital lifeline ensuring the CDU's stable operation.

• Sudden pressure drop → Risk of leakage, pump cavitation, server downtime

• Excessive pressure differential → Filter clogging, insufficient flow, cooling failure

• Pressure fluctuation → Water hammer, pipeline fatigue, system precision drift

Our Solutions: Designed for Liquid Cooling Applications

To meet the liquid cooling industry's stringent requirements for stability, safety, and reliability, we officially launch the M20H pressure transmitter, designed specifically for liquid cooling applications.

Rely on 50 years of experience in sensor technology and specifically tailored to the operating conditions of liquid-cooling CDU systems, the M20H pressure transmitter precisely monitors inlet and outlet pressures, filter pressure differentials, and post-pump pressure. They provide reliable data for leak protection, pump speed regulation, blockage alerts, and safety interlocks, thereby ensuring the safe, efficient, and stable operation of liquid-cooling systems.
