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.

The Alphacool Core reservoir combines performance with design. The tube of the reservoir is made of acrylic, the D5/VPP pump top and the lid of acetal.
