Matthew Maleki, Carrier product manager who headed the compliance project, said: “The specification was challenging and there were no standard factory-produced chillers available that were compliant. For example, the requirement for zero halogen, low-smoke cables required a completely new chiller wiring loom. The changes to the standard factory specification required detailed research on alternative components and their application. The bespoke chillers are equipped with zero halogen, low-smoke insulation and cables, and finished with specialist paint, all formulated to emit very limited smoke and/or fumes when exposed to heat or flame. Fifteen customized Carrier AquaSnap air-cooled liquid chillers with Greenspeed Intelligence will provide resilient, reliable cooling for new Elizabeth Line stations at Tottenham Court Road, Paddington, Woolwich and Farringdon.Ĭarrier’s UK team worked closely with its chiller research and development centre in Montluel, France, to develop a solution that met the strict fire prevention requirements for the project, due to its underground location.
