The Alphacool ES 4U Reservoir with D5 top is a development for the Enterprise Solutions series. It has an integrated pump top for powerful D5 pumps. The combination of pump top and reservoir was designed to be mounted directly in the front of 4U servers. The positioning of the reservoir in the enclosure and the acrylic cover used make maintenance and control of the water circuit much easier.

Connection options
The ES 4U Reservoir has a total of 3 inlets and one outlet. All connections use a G1/4" thread. 2 inputs are located on the acrylic cover in the front range. The reservoir can be perfectly filled or emptied via these inputs. The input and the output for integrating the reservoir into the water circuit are located on the back.

Assembly & maintenance
The ES Reservoir is mounted in the front of a 4U server rack. The acrylic cover allows visual control of the water cooling level. The G1/4" inlets in the cover allow easy filling, draining and venting of the water circuit.

Compatibility
The ES 4U Reservoir has an integrated pump top and is compatible with all original D5 pumps as well as all Alphacool VPP pumps. The pump retaining ring, a pump O-ring and all screws are included in the scope of delivery.

(Note: The pump shown in the installation example is not included in the scope of delivery!)
