The Alphacool ES 2U Reservoir is a versatile expansion tank optimized for use in 2U server cases. The quick-release fittings on the front make maintenance fast and easy. With integrated flow and temperature sensors, the cooling system can be continuously monitored. The illuminated viewing window allows for easy reading of the fluid level at any time.

Optimized for servers, the Alphacool All-in-One expansion tank has been specifically designed for 2U server cases. The unit is compactly built to take up minimal space in the server case. Thanks to the quick-release fittings on the front, the cooling system can be filled and bled quickly and easily. The illuminated viewing window allows for constant monitoring of the fluid level in the system. The Alphacool ES 2U Reservoir is compatible with D5-format pumps, such as the Alphacool VPP Apex.

The reservoir features a temperature sensor that covers a measurement range of -40 to 125 °C and connects to the motherboard via a 2-pin connector. Additionally, a flow sensor, which connects via a 3-pin connector, enables continuous monitoring of the water flow in the cooling system.
