Oakes Energy Services replaced two failed chillers at a major London hospital with high-efficiency Keyter units as part of an NHS Trust’s initiative to enhance mechanical resilience and patient comfort. Operating in a live hospital environment, the team managed the decommissioning of old equipment, coordinated two crane lifts, and integrated the new chillers into the hospital’s building management system (BMS). Due to severe winter weather, the planned crane operations were delayed, but our agile project management and close coordination with the hospital’s estates team ensured the timeline was protected and safety was prioritised throughout.
To maintain uninterrupted cooling for critical services such as theatres and wards, a phased installation strategy was adopted. One chiller was replaced and commissioned at a time, enabling seamless operation and smoother integration. Despite weather challenges, the project was completed on time and within budget, with zero disruption to hospital services. The new chillers provide improved energy efficiency, reduced maintenance needs, and increased reliability delivering long-term performance and sustainability benefits to the Trust.
