Chloride Power Protection was recently commissioned by M&E contractor Lorne Stewart to provide critical back up power for the Driver and Vehicle Licensing Agency's (DVLA) two new data centres at in Swansea. Three Chloride 90-NET 500KVA UPS modules have been installed at the first new data centre on the site of the DVLA headquarters. Working in modular parallel redundant mode these have been selected with 20 minute batteries to match the load requirements and interface with the existing systems. The Agency's second new data centre has the same 90-NET 500KVA UPS units, but here Chloride has also supplied a new 2.5MVA prime rated diesel generator system, complete with 24,000 litre capacity bunded bulk fuel tank. Due to space restrictions this system has been custom-designed to fit into a 12 metre enclosure. Both the UPS and generator systems can be linked to Chloride's LIFE.net remote service monitoring systems.
