The London Eye
The operator of one of London’s most visited and recognisable landmarks – a South Bank observation attraction visited by millions of people each year.
The attraction relies on a sophisticated climate control system within its passenger pods to maintain visitor comfort throughout the year. As part of a planned upgrade programme, the existing package chiller units in 10 pods required replacement – within the unique spatial and access constraints of a continuously operating attraction, without disrupting the daily visitor experience.
JSA Service developed a comprehensive mechanical and electrical approach in close collaboration with the site engineering team. Works included supply and installation of brazed connectors onto new package chiller pipework, on-site brazing in designated outdoor areas, full pressure leak testing of all new joints, and supply and installation of prefabricated 5-pin electrical connectors to simplify and accelerate wiring on each unit.The project was delivered on programme, with zero disruption to the attraction’s daily operation. All 10 pods now benefit from reliable, efficient climate control – and JSA Service continues to support the installation on an ongoing maintenance basis.
