Cooling performance starts with water quality

As rack power density increases and cooling technology moves closer to the heat source, the requirements for cooling water quality become more demanding. Deposits, corrosion products and biological growth can impair heat transfer, restrict narrow flow channels and increase the effort and the power usage required to operate the cooling system.

Data centers can use open evaporative cooling systems, closed cooling loops or combinations of both. Each configuration places different demands on water quality, treatment and monitoring. Open cooling towers are exposed to evaporation, airborne contamination and increasing salt concentration. Closed loops also require controlled filling, chemical conditioning and monitoring. Precise dosing of inhibitors, pH correction chemicals and biocides helps maintain reliable operating conditions in both types of circuit.

Continuous monitoring for early intervention

Continuous measurement of parameters such as pH, conductivity, redox potential, disinfectant concentration, turbidity and corrosion indicators makes deviations visible at an early stage. Linking measurement data with dosing and blowdown control enables faster responses to deviations and supports stable, resource-efficient operation. This provides the flexibility to react promptly to unforeseen events.
