Subsystems
Every CGiX site is assembled from factory-integrated modules — each one built, wired, and tested before it ships. Here's what's inside.
SUBSYSTEMS The module breakdown
Subsystem 01
The compute white-space
High-density rack bays with contained service and airflow zones, facility-side AC busway, liquid-cooling distribution and CDU interfaces, environmental monitoring, and leak detection — prepared for customer-furnished GB300-class racks.
| Quantity | 2 modules |
|---|---|
| Rated capacity | 2.4 MW IT each |
| Arrangement | 2 modules = one 4.8 MW ComputeBlock |
| Electrical basis | 480 V / 60 Hz |
Subsystem 02
Medium- & low-voltage distribution
A prefabricated module integrating MV input switchgear/RMU, transformer, IT UPS, mechanical UPS, LV main switchboard, protection, metering, and outgoing interfaces — factory-assembled and FAT-tested as one unit.
| Quantity | 4 modules |
|---|---|
| Rated capacity | 2,750 kVA transformer each |
| Redundancy | 4-to-make-3 distributed |
| Electrical basis | Project MV in · 480 V LV |
Subsystem 03
Liquid cooling + residual air
A factory-integrated liquid-cooling and residual-air package — CDU capacity, fan-wall unit, pumps and valves, temperature and pressure sensing, local controls, and BMS interface. Separates facility water from the customer rack loop.
| Quantity | 4 skids |
|---|---|
| Rated capacity | 1,000 kW CDU · 200 kW fan-wall |
| Redundancy | N+1 (final validation req.) |
| Electrical basis | 480 V / 60 Hz |
Subsystem 04
Heat rejection
An adiabatic dry cooler with VFD/EC fans and a high-temperature water/glycol circuit — pumps, valves, strainers, sensors, water-treatment provisions, local controls, and BMS interface. Serves outdoor or indoor prefabricated IT modules.
| Quantity | 4 modules |
|---|---|
| Rated capacity | 1,440 kW each |
| Redundancy | N+1 |
| Electrical basis | 480 V / 60 Hz auxiliary |
Subsystem 05
Standby generation
A factory-packaged standby engine-generator with starting system, local controls and monitoring, output breaker, and external fuel, power, and control interfaces. A weatherproof/enclosed package for outdoor or indoor deployment.
| Quantity | 4 modules |
|---|---|
| Rated capacity | 2,750 kVA / 2,200 kW standby each |
| Redundancy | 4-to-make-3 |
| Electrical basis | 60 Hz · output project-defined |
Subsystem 06
On-board energy storage
Integrated battery storage brings ride-through, peak-shaving, and energy-market participation to the platform — the same capability proven on the CGiX-Mini line. Configuration and sizing for the large-module tier are in engineering.
| Status | In development for this tier |
|---|---|
| Proven on | CGiX Mini · 750 kWh–3 MWh |
| Function | Ride-through · peak-shaving · VPP |
| 4.8 MW config | To be confirmed |
Every module is factory-integrated and FAT-tested before shipment — the unit arrives as one system, not a kit. Quantities and redundancy reflect the 4.8 MW module basis; specifications are preliminary and subject to engineering review.
