Prefabricated Data Center — Factory-Built Rooms and Modules
Factory-built data center rooms and modules with power, cooling, containment and monitoring.
A prefabricated data center is a factory-built hall or module containing 10 to 100+ racks, power, cooling and containment. It is shipped to site, connected and commissioned, typically in 8 to 20 weeks, with less site labor than a conventional build.

Prefabrication moves cutting, wiring, piping and testing into the factory. Site work is limited to foundations, connections and commissioning.
The project defines module size, power and cooling density, and the interface between modules.
Best for
- Fast-track data center projects
- Sites with limited skilled labor
- Repeatable capacity expansion

Define interfaces
Power, water, network and fire interfaces.
Plan site assembly
Confirm crane, foundation and commissioning sequence.
What prefabricated means
A prefabricated data center is built as modules or complete halls in a factory, then transported to site. The modules include the structure, racks, power, cooling, containment, fire suppression and monitoring, so site work is limited to foundations, connections and commissioning.
It is used for rapid deployment, remote sites, temporary capacity and projects where local construction labor is limited. The factory environment improves quality control and shortens the schedule.
Module types and capacity
Common forms are ISO-container modules, skid-mounted modules and walk-in halls. A single module can hold 10 to 20 racks; a multi-module hall can hold 100 or more. Capacity is sized by IT load, cooling and power.
The module footprint depends on the rack count, aisle width and service clearance. Confirm the transport route, crane access and foundation design before shipping.
Power, cooling and efficiency
Prefabricated modules use integrated UPS, switchgear, busway and row or perimeter cooling. Containment and sealed envelopes allow a higher supply temperature and a PUE of about 1.2 to 1.5. Free cooling is possible in suitable climates.
For critical sites, use N+1 or 2N power and cooling. Confirm the fuel storage, generator interface and fire suppression requirements with the local authority.
Delivery and commissioning
Typical lead time is 8 to 20 weeks after drawing approval, depending on the module count and the power/cooling configuration. Site work includes foundations, module placement, power and network connection, cooling commissioning and integrated systems testing.
