The Multi Scenario Modular AIDC Solution is a set of reference architectures designed for AI data centers built around high-power GPU racks. Today’s AI data centers face unprecedented cooling challenges: the latest GPUs and CPUs generate significantly more heat than their predecessors, while rack densities continue to climb. With rack power often exceeding 30 kW per cabinet, traditional air cooling reaches its physical limits.
In EPG’s approach, cold plate liquid cooling (direct-to-chip) becomes the primary cooling technology, removing about 75–80% of the heat load from GB200 NVL72-class racks, with the remaining 20–25% handled by air-cooling systems. EPG demonstrates four different scenario solutions (“Zones”) that integrate power, cooling and IT PODs to address a variety of site conditions.

Key Features
Zone 1 – Air Cool & LC Mixing, 2N Power, Air-Cooled Chiller

2N power architecture with 11 kV medium-voltage Gensets in 2+1 configuration, two MV SYNC PODs, two transformer PODs and two LV PODs. Cooling uses a mixed scheme of liquid cooling station POD and air-cooled chilled water system. The liquid cooling station provides cold source for cold-plate servers via CDUs in the IT POD, while air-cooled chillers supply CRAH units. One IT POD is assembled from four IT containers with 16 Nvidia GB200 NVL72 server cabinets and a total IT load of 2 MW.

Zone 1 – Air Cool & LC Mixing, 2N Power, Air-Cooled Chiller
Zone 2 – Air Cool & LC Mixing, 2N Power, Water-Cooled Chiller POD

Similar 2N power distribution, but cooling adopts a mixed scheme of liquid cooling station POD and water-cooled chiller station. The water-cooled chiller station supplies cooling to Room CRAHs; the LC station again provides cold source to cold-plate servers via CDUs. IT POD composition is the same (4 IT containers, 16 GB200 NVL72, 2 MW).

Zone 2 – Air Cool & LC Mixing, 2N Power, Water-Cooled Chiller POD
Zone 3 – Integrated Cooling Source, DR Power, Waste Heat Recovery

DR power system with two MV PODs as power A and B, three transformer PODs and three LV PODs, each matched with a 400 V Genset. Under normal conditions each LV POD runs at ~66.7% load; when one fails, the others rise to 100%. Cooling uses a hybrid scheme of liquid cooling station PODs, air-cooled chillers and a heat-recovery POD. Chilled water first supplies indoor CRAH units and then CDUs for liquid-cooled racks.

Zone 3 – Integrated Cooling Source, DR Power, Waste Heat Recovery
Zone 4 – Integrated Cooling Source, DR Power, Magnetic Levitation System

DR power configuration similar to Zone 3, but the cooling scheme uses a magnetic levitation phase-change system where air and liquid cooling share the same refrigeration system. The outdoor magnetic levitation units provide refrigerant to end devices inside the IT POD, including CDU, FWU, CRAC, In-Row AC, thin-plate fan walls and top fan coils.

Zone 4 – Integrated Cooling Source, DR Power, Magnetic Levitation System
