Alphacool 1017716 ES 2U DDC Pump Top Reservoir Black

Enterprise 2U Reservoir

The Alphacool ES 2U reservoir integrates a DDC pump top into a single unit built for 2U server racks and workstations. It combines the expansion tank and pump mounting into one compact component. The black finish suits professional chassis aesthetics. Model 1017716 identifies this specific enterprise solution.

G1/4 Connectivity

Eleven G1/4 threaded ports provide ten inputs and one output for flexible loop routing. Ports are distributed on the sides and top to simplify filling and bleeding operations. The unit measures 62 x 80 x 60 mm to fit tight rack spaces. Three mounting frames and a double nipple fitting enable direct attachment to compatible Alphacool X-Flow radiators.

Loop Integration

This reservoir replaces separate pump tops and tanks in custom liquid-cooling loops where rack density is critical. The integrated design reduces component count and potential leak points in enterprise deployments. The jump is worth it when a single-slot 2U form factor and extensive port layout are required for the build. Builders needing larger capacity or different pump formats should look elsewhere.
