Weakest‑Link Consolidation (per unit)
- Area Class: For non‑H₂ service, Zone‑1 IIB T3 via chiller. For H₂ service, configure IIC T3 end‑to‑end (tank shower IIC variant + chiller certification to be matched in submittals).
- IP Baseline: IP55 due to pump motor; check MR minimums for instruments/motors; deviation only if motor IP65 mandated.
Auto‑Flags
- Weakest_Link_Flag: TRUE (Area Class = IIB via chiller for non‑H₂; IIC configured for H₂; IP weakest = IP55 motor).
- Dual Power: TRUE candidate — Offer indicates 415 VAC 3Φ chiller plus 230/240 VAC shower feed (Offer p.4 lines 364–366; Datasheet lines 109–113).
