The Langham Hotel

Life-safety standby generation

Consultants for London’s Langham Hotel appointed YorPower to design and deliver a replacement backup system for key services and life-safety loads.

Turnkey scope

• Decommission and remove the original roof-level equipment.
• Design structural steelwork and complete mechanical and electrical works.
• Supply a 450kVA Volvo-powered generator in a bespoke acoustic enclosure.
• Install digital controls for grid synchronisation and parallel operation.
• Test, commission and provide warranty, servicing and maintenance support.

Restricted-access installation

Sunday road closures allowed crane access. Engineers dismantled the original engine, alternator and ancillary equipment inside the difficult-to-access plant room. Components travelled up a lift shaft to the roof for removal. The new set followed the reverse route in sections, then was reassembled and connected inside the plant room.

Noise and vibration

Special vibration-damping mountings supported the structural steelwork. Three silencing systems were incorporated to limit disturbance when the generator starts automatically, protecting the hotel environment while providing standby power.
