The Alphacool ES Reservoir DDCzero 1U with Pump is a compact, professional-grade reservoir and pump combination engineered specifically for 1U rackmount servers, data centers, and industrial liquid cooling applications. Its ultra-low-profile design allows it to fit into space-constrained environments while delivering the reliable coolant circulation required for continuous operation.

Constructed entirely from durable acetal, both the reservoir body and top are designed for maximum strength and long-term reliability. The five integrated G1/4" ports provide flexible options for inlet, outlet, fill, and drain configurations, while the threaded connections are machined directly into the acetal housing to ensure secure, leak-resistant fittings without placing stress on more fragile materials.

Standing less than 42 mm tall, the ES Reservoir DDCzero 1U is purpose-built for rackmount installations where every millimeter matters. The reservoir has been pressure tested up to 4 bar and is recommended for operating pressures up to 2 bar, making it well suited for demanding enterprise cooling systems requiring dependable performance.

The integrated Alphacool DDCzero PWM pump delivers up to 220 L/h of coolant flow with a maximum head pressure of 1.4 meters. PWM speed control allows the pump to operate between 3,000 and 4,800 RPM, enabling system builders to optimize cooling performance while minimizing noise and power consumption. A durable ceramic shaft and robust construction ensure dependable long-term operation in 24/7 environments.

Whether deployed in enterprise servers, HPC clusters, industrial equipment, or compact workstation cooling systems, the Alphacool ES Reservoir DDCzero 1U provides a reliable, space-efficient solution that combines flexible connectivity, durable construction, and efficient pump performance in a single compact unit.
