Cabinet-Type In-Row CDU 500–2000 kW

Quick AnswerCabinet-Type In-Row CDU ⁦500–2000⁩ kW — an IDCPDU CDU for liquid-cooled high-density racks.

Hot-swap pumps and filters — A pump or a filter is changed while the loop keeps running, so maintenance stops being a scheduled capacity outage.
Duty + standby pumps and feeds — Pump and power feed are both 1+1 — a single failure eats margin, not the whole loop.
Dew-point supervision — Condensation is the failure nobody sees coming; the control tracks dew point and acts before water forms on a cold plate.
Filtration on the coolant side — The filters protect cold-plate micro-channels; one blocked channel is a hot GPU that no amount of airflow will fix.

⁦500–2000⁩ kW cabinet with redundant pumps and dual power feeds.
One unit carries a full row of high-density AI racks.
Liquid-to-liquid plate exchanger keeps the IT loop sealed.
Inside the cabinet a duty pump and a standby pump run in parallel, each on its own power feed, and both ramp with load instead of running at fixed speed. If one feed drops or one pump faults, the other takes over without interrupting flow or temperature difference on the IT side.
Control covers the failure modes that matter in an unmanned hall: dew point tracking with anti-condensation heating, leak detection in the cabinet sump, undervoltage monitoring, heat-exchanger fouling detection, and dual pressure protection with automatic relief. Power-fail memory restores the last setpoint and restarts the unit when supply returns; readings reach the local touch panel, web portal and mobile app.
Five capacities — 500, 800, 1000, 1500 and 2000 kW — share a 2000 mm height and 1200 mm depth, in widths from 600 to 1200 mm. The primary loop runs at 30/40 °C and the secondary at 40/50 °C, so facility water stays well above the dew point of the room.
The cabinet stands alongside the racks with no plant room and no ducting, which makes it the smallest change for an air-cooled hall moving to direct-to-chip. Primary 200 µm and secondary 100 µm filters, with pumps and heat exchanger replaceable while the loop runs, keep maintenance inside the row.
