Rolls-Royce has delivered a backup power system for a Chinese data centre.

The system consists of ten 20 V diesel-fired series 4000 MTU engines, which are installed at a height of 33 metres on the roof of internet service provider Sinnet’s new data centre in eastern Beijing, with the diesel fuel stored in eight underground tanks.

Sinnet operates eight data centres featuring 1220 server cabinets on an area of over 11,000 square metres, which need to be protected in the event of power failure.

The new system represents the firm’s fourth use of MTU gensets for emergency power.

The gensets were delivered in August and commissioned in late October by power integration firm Tianjin Pauway Power Equipment Co Ltd, Rolls-Royce said.

Pauway president Hao Liu said: “Our customers depend on us ensuring that the data flow is maintained at all times – even a power outage must not lead to any disruption or impairment of our service whatsoever.”
