Oxford University Hospital, Mayfair Theatre, Oxford, London

“Temperature Controls professional and sustainable approach has meant project savings were achieved. The project was delivered on time and budget and the testing and commissioning to meet HTM03 strict specification was carried out to a high level.”


Precise chilled water and ventilation required for maintaining safe working conditions for temperature/humidity control whilst maintaining a correct pressure regime to maintain infection control of the new operating theatres and recovery unit.

Project Overview

The existing operating theatres are approximately 8 years old and fully functioning. Where possible, the brief was to utilise all existing services and to modify and adapt existing systems to accommodate and expand the facility to a new location within the hospital grounds.

In the event of system failures, the new facility requires resilience whilst re using existing equipment and materials where possible.

Temperature Control Limited carried out and assisted with the design, alongside the project’s consultant team and proceeded to carry out the build of the precise chilled water and ventilation systems to accommodate the new operating theatres and recovery suite.

Project Description

Temperature Control designed, installed, tested, commissioned and set to work a complete chilled water cooling system to provide 4°C chilled water to the AHU cooling coils, using 20% glycol, at the flow rates required by the AHU supplier, to supply cooling coils at the precise temperature and delivery in order to maintain design conditions.

In order to maximise energy efficiency savings, a new A-rated chiller was provided which is preferentially loaded and acting as the ‘lead chiller’. All necessary works were carried out to re-use the existing Aermec chiller and integrate it into the new cooling system in order for the existing chiller to operate in high load conditions to provide additional ‘top up’ cooling but mainly for redundancy.
