• Ecolab says a contractor filled a direct-to-chip cooling loop with municipal rather than deionised water, leading to about a week of downtime
  • Ecolab's direct-to-chip systems monitor coolant concentration, temperature, pH and flow, and the company includes commissioning support in its cooling services

The fact

A mechanical contractor filled a direct-to-chip cooling loop at an unnamed data centre with municipal water instead of deionised water, leading to about a week of downtime, Capacity reported, citing Ecolab. Ecolab also attributed millions of dollars in lost revenue to the incident. The data centre, its location and the timing of the failure were not identified in the report.

Ecolab provides water treatment and cooling services for data centres. Its direct-to-chip technology monitors coolant conditions including concentration, temperature, pH and flow, while its service offering includes support during commissioning and start-up. The company says those controls are intended to identify problems with coolant condition before they affect servers or cooling equipment.

The assessment

The Ecolab case shows how a cooling problem can begin before a server is running. The pipework may be installed correctly, but filling the loop with the wrong fluid can leave the system unfit for operation even though the mechanical work appears complete.

That makes the fill itself part of commissioning. Contractors need to know the required coolant, while operators and cooling suppliers need a way to confirm what entered the loop before accepting the system. In this case, a mistake made during installation reportedly carried through into a week of downtime. What the incident does not tell us is how often similar errors occur elsewhere. For BTW readers, the practical lesson is at handover. Direct-to-chip cooling adds another condition that has to be checked before IT equipment goes live: not just whether the loop works, but whether the fluid inside it is the right one.

What to watch

Watch whether data centre operators and liquid-cooling suppliers make coolant specifications, flushing records and chemistry tests explicit handover requirements. Commissioning checklists, equipment warranty terms and named incident reports would show whether fluid verification is becoming a standard control for direct-to-chip deployments rather than a response after failures occur.
