Adiabatic Project Complete

February 2024

This project involved the replacement of three Transtherm Adiabatic Cooler Units on the rooftop of the main Chelsea and Westminster Hospital with nine new units.

The aim of the project was to replace the existing failed units with new units incorporating the latest technology, including remote monitoring/ control facility, allowing the manufacture to monitor the units if requested and improve the hospital’s overall efficiency, ensuring the Combined Heat & Power (CHP) plant, “heat engine”, had the necessary additional cooling to maintain   a comfortable and safe environment for patients and staff.

However, the project wasn’t without its challenges. The site was situated in a highly congested area, surrounded by several buildings, including residential apartments to the west, residential properties to the south, and high street businesses and residential properties to the north.

The project required meticulous planning, coordination, and constant communication with all stakeholders to ensure that the hospital’s daily operations were not disrupted.

After careful selection of cranes to suit the different lifts, all crane lifts had to be coordinated with the hospital ambulance service to ensure there was no impact on patient transfers. This included posting notices before the day of the lift and on-site coordination with the staff the day of the lifts.

Despite the challenges, including the late instruction to install a new submains cable and panel board with metering with the new cable installed through public areas, the project was completed successfully without disrupting hospital services or daily operations.  The team worked tirelessly to ensure that the project was completed within the set timelines and budget, while upholding the highest standards of quality.
