GPU WORLD · GW-LC-CDU-30L
30 kW planning class liquid-to-liquid CDU
Facility interface reviewTransfer heat from the equipment coolant loop to facility water through a heat exchanger. Confirm the operating conditions on both sides before selecting the unit.
Fit and compatibility
- Provide facility-water supply and return temperatures, available flow, permitted pressure drop and water quality. Confirm connection size, location and isolation points.
- Provide the technology loop’s allowable supply temperature, fluid specification, flow and external pressure drop. Check rack space, power and service access.
Scope of supply
- Agree on the CDU, heat exchanger, pumps and equipment loop connections. Identify who supplies the facility-side valves, strainers, fittings and piping.
- Confirm the controls interface and sensor list. Request a piping and instrumentation diagram, coolant compatibility data and test curves for the chosen duty.
Operating conditions
- Facility water and equipment coolant follow separate paths through the heat exchanger. Verify the approach temperature, which is the difference between the equipment and facility supply temperatures at the CDU.
- Use the 30 kW planning class to request performance data at the agreed approach, flow and fluid on both loops. Confirm pump head and the facility-side pressure drop.
- Review the dew point, insulation and control strategy for surfaces exposed to the room. Agree on cleanliness and chemistry limits for each loop.
Acceptance checks
- Verify circuit cleanliness, isolation and pressure integrity under the agreed commissioning procedure. Record both loop flows, temperatures, pressures and measured approach at design load.
- Check the controls and telemetry, including low flow and high coolant temperature alarms. Test switchover when the selected unit includes redundant pumps.
