SAVRN Atom
Built by IntelliFlex
SAVRN designs, builds and delivers AI data centers. The Atom is what it delivers. Five standard modules bring compute, cooling, power distribution and operations together in one 13.2 MW unit, 255 feet 6 inches end to end. It carries 8.8 MW of IT load and up to 80 rack positions. Three optional modules add power continuity and generation. Four Atoms on one shared spine make 52.8 MW, 35.2 MW of IT load and 320 rack positions.

Compute
Four IT modules, forming two IT halls, sit either side of the interconnecting module. Together they hold up to 80 racks and 8.8 MW of IT load for the Atom.
Two IT halls, each built from two factory-made IT modules, hold 80 rack positions in four rows of 20. Each hall draws from its own six busways and its own chiller plant, so the halls run as two independent halves of the Atom. Racks are direct-to-chip liquid-cooled, and CRAH units along the rows take the heat that does not leave in the liquid and condition the hall air.

Cooling
Four chiller buildings, two at each end of the Atom. Each houses three chiller trains (dry cooler, chiller and pumps), with its dry coolers on the roof. Together they form two chiller plants, one per IT hall: six trains each, five required (N+1), on 2N chilled-water headers.
Four chiller buildings, two at each end of the Atom, form two chiller plants, one per IT hall. Each plant runs six chiller trains, each a roof-mounted dry cooler, a chiller and a facility pump assembly, and five of the six carry the load. Chilled water leaves each plant on 2N supply headers to one cooling system in each IT hall: distributed pumping assemblies feeding direct-to-chip liquid cooling at the racks, and CRAH rows that take the heat that does not leave in the liquid and condition the hall air.

Megabox
Beside IT hall Southeast: six unit substations, MB-01 to MB-06. Each steps 12.47 kV down to 415 V and feeds two 2,100 A busways.
Six unit substations beside the IT halls, one Megabox on each of the six 3 MW feeders. Each takes 12.47 kV from its MV BESS+ unit, steps it down to 415 V through a dry-type cast resin transformer, and feeds two 2,100 A overhead busways, one to each IT hall and its chiller plant.

In the power yard, one building per Atom, between power generation and the MV-BESS: a main incoming section and six 3 MW feeder sections.
A standalone building in the power yard with the main incoming section and six 3 MW feeder sections, one for each Megabox. It accepts up to three power sources, with an optional transfer switch and optional SCADA. The number of incoming feeds and the switchgear design are set for each site.

Control room
Customizable to the project. The four-Atom layout places it at the south end of the shared spine.
The operations module for the Atom: operator stations, central servers and network racks, with workspace and restroom or change facilities. The building management system here supervises both halves of the Atom, each run by its own redundant controller pair.

Optional. Not shown on these drawings; it joins the power path when a project specifies it.
A diesel rotary uninterruptible power supply combines a flywheel and a diesel engine in one machine. It is the alternative to MV BESS+ as the uninterruptible stage: six units in a 6-to-make-5 arrangement with 12.47 kV output, carrying the Atom through an interruption on flywheel energy while the engine starts.

Medium-voltage battery energy storage. In the reference design, which follows Uptime Institute Tier III topology criteria, each of the six Megaboxes has a 3 MW MV BESS+ unit ahead of it. Five carry the 13.2 MW Atom and the sixth is redundant (N+1). Each unit conditions voltage against sags, swells and transients as well as riding through outages.
