CDU Mini-BMS · Instrument view

Layout, P&ID & live parameters — per CDU type

A miniature building-management cockpit for liquid-cooling Coolant Distribution Units. Pick a CDU type to see where it sits in the datahall, how its piping & instrumentation is arranged, and a live (simulated) parameter feed. Inject a fault and watch the control logic respond — the same flow, pressure, temperature, pump-redundancy and leak signals a real CDU controller exposes to the BMS/DCIM.

How to read a tile: FT-01 instrument tag (matches the P&ID) · big value & unit · the bar shows the normal band (shaded) with a marker for the live value · the status line reads NORMAL / WARN / ALARM. Click a tile for its trend & reference.

Educational simulation — not a live feed. Values are generated on-device from typical operating bands (see the CDU Checklist §01–§03 for the sourced parameter ranges, ASHRAE TC 9.9 W-classes and OCP cold-plate guidance). Parameter targets: secondary supply ~17–45 °C · ΔT ~8–12 °C · flow ~1.0–1.5 LPM/kW · dP ~0.5–3.0 bar · system pressure ~2–6 bar · pumps N+1 · leaks 0. Each injected fault maps to an FMECA liquid-cooling fault mode — leak → F11.3 (manifold/hose leak), pump-fail → F11.2 (CDU-pump failure), filter clog → F11.5 (filter clogging) — catalogued with mechanisms, effects, corrective actions and RPN risk in the AI Engineering Maintenance FMECA knowledge base. Confirm exact set-points and alarm limits against the specific CDU's manufacturer manual. Not procurement, safety, or engineering advice.
