Summary

Delta Electronics, founded in 1971, presents its comprehensive data center cooling portfolio spanning in-row cooling (room cooling, chiller water, direct expansion, rear door heat exchangers), liquid-to-air CDUs (300 kW featured unit on display at booth 51), liquid-to-liquid CDUs, and single-phase immersion cooling. Delta positions itself as uniquely capable, claiming to be the only CDU supplier with mass-production-level shipment quantities to two of the "big four" CSPs. The presentation touches on Delta's broader sustainability mission and data center product portfolio including UPS, in-row power, power trains, and containerized data centers.

The company also supports the OCP Dashcool project (Google-initiated) with a dedicated CDU unit and chief engineer. Their single-phase immersion cooling solution minimizes pool boiling effects (POE) and coolant evaporation concerns while providing full-scale server cooling for all electronics. The presentation emphasizes that 44% of companies currently recognize sustainability importance, projected to reach 78% the following year, with Microsoft cited as an example where saving 1% of rack power consumption (~5 kW) can power several additional servers.
