In-Row Air to Liquid CDU (Sidecar)

The In-Row air-to-liquid CDU (Sidecar) integrates control, pumb power, buffering, and heat exchange systems into a single unit. Through a circulation pump, coolant with constant pressure and flow rate is continuously delivered to the supply-side pipeline and evenly distributed to each rack via a data center manifold.After absorbing heat from server nodes, the coolant flows back through the return-side pipeline and exchanges heat with the primary-side room cooling air through the CDU heat exchange module. The heat is then discharged into the data center environment and ultimately removed by the air-conditioning system.The cooled coolant returns to the circulation pump, is pressurized, and re-enters the supply-side loop, forming a closed-loop cooling circuit.

PRODUCT FEATURES：

◆ Cooling capacity: 60–1050 kW, suitable for small- and medium-scale data centers without primary chilled water infrastructure.
◆ Redundant design for key components, dual power inputs, supporting online maintenance.
◆ N+1 redundancy for pumps, fans, and control sensors, and  secondary-side filters.
◆ Three control modes:differential pressure, constant flow, and constant temperature.
◆ SUS304 stainless steel piping, high reliability and good coolant compatibility.
◆ Secondary side compatible with both top and bottom piping configurations.
◆ Integrated real-time water quality monitoring module for online detection of pH, conductivity, and turbidity.
◆ 7-inch LCD touch screen with PLC controller and integrated monitoring of temperature, flow rate, pressure, leakage, and liquid level.
◆ Supports Modbus RTU, Modbus TCP/IP, and SNMP protocols.
◆ Three-level alarm mechanism for rapid fault diagnosis.
