The Alphacool ES 4U reservoir with D5 top is a development for the Enterprise Solutions series. It features an integrated pump top for powerful D5 pumps. The combination of the pump top and reservoir is designed for direct mounting in the front of 4U servers. The positioning of the reservoir in the case and the use of an acrylic cover greatly facilitate maintenance and monitoring of the water circuit.

The ES 4U reservoir has a total of 3 inlets and one outlet. All connection options use a G1/4" thread. Two inlets are located on the acrylic cover at the front. These inlets allow for perfect filling or draining of the reservoir. The inlet and outlet for integrating the reservoir into the water circuit are located on the back of the reservoir.

The ES reservoir is mounted at the front of a 4U server rack. The acrylic cover allows for visual monitoring of the coolant level. The G1/4" inlets in the cover enable easy filling, draining, and bleeding of the water circuit.

The ES 4U reservoir features an integrated pump top and is compatible with all original D5 pumps as well as all Alphacool VPP pumps. The pump holder, a pump O-ring, and all screws are included in the delivery.
