The FusionDC1000C prefabricated modular data center integrates civil engineering (L0) and electromechanical infrastructure (L1). The core functional area adopts modular design that the core modules are prefabricated, pre-integrated, and pre-commissioned in the factory, and LEGO assembly onsite. The construction of the auxiliary areas by engineering mode. So, it can minimize onsite workload, supports simplified, fast, and green deployments. Core modules Generally include IT equipment modules, power modules, battery modules, and cooling modules.
