Situated in Hemel Hempstead, 35km northwest of London, the NTT HH4 Data Centre provides 4,800m² of server space with a total IT load of 12MW. Built to support high-performance IT environments, it features a centrally managed primary cooling infrastructure with a minimum of N+1 redundancy and full integration into the building management system (BMS) for climate and humidity control across multiple data suites.
Pipetech was engaged over two phases to supply, fabricate, and install all pipework for the cooling infrastructure, including DN400 carbon steel pipework as the primary distribution size. The scope also included the offsite assembly and delivery of five prefabricated plantrooms, enhancing quality control and reducing onsite installation time. In addition, Pipetech completed the fit-out of six data halls, installing a total of 60 CRAH units with preassembled valve arrangements to streamline the programme. All work was delivered to high standards of quality assurance, supporting system reliability and rapid commissioning for this critical facility.
