Robur gas chillers solve power shortage at Embassy Gardens
Faced with a shortage of electrical power and the cost of providing the necessary power, 128 Robur gas-powered chillers have been installed to provide comfort cooling to six residential apartment buildings at Embassy Gardens, the landmark development in Nine Elms, London. More than 2.3MW of cooling have now been provided across three phases of the residential build.
Embassy Gardens is a 17-acre site in the heart of the Nine Elms regeneration area which will deliver 1,750 new homes, 20,000m2 of commercial space and 12,077m2. of retail. Nine Elms is one of Europe’s most significant regeneration projects, comprising thousands of luxury homes, workspaces and amenities as well as the new US Embassy, Battersea Power Station and New Covent Garden market.
The Robur chillers, supplied by UK distributor ESS, are mounted on factory-assembled skids, pre-wired and pre-piped, each of which has a 90kW output but requires just a 30 Amp single phase power supply. The integrated controls automatically "cascade" the chiller modules and share the load evenly between each of them.
Kevin Pacey, managing director of ESS, says: "The Robur gas powered chillers provide a truly modular solution. The direct digital controls ensure shared workload and, in the event of a mechanical failure or service downtime, less than 7% of output is lost.”
Robur offers energy-efficient gas-powered heating and cooling solutions which reduce any environmental impact. Robur gas chillers and heat pumps use natural refrigerant in a factory sealed circuit and are not subject to F-Gas regulation. Global warming potential (GWP) and ozone depletion potential (ODP) are both zero, earning credits for BREEAM. Moreover, due to an almost static refrigeration cycle, the performance levels will remain unchanged over time.
