Air System Commissioning a Surgical Theatre

Surgical Theatres Air System

Surgical theatres and patient recovery bays require the highest level of hygiene and sterilisation. A big part of that is ensuring the air is well circulated. That sounds easy but its not just a case of opening a window. It is all about ensuring the ductwork and Air Handling Units (AHUs) are all working together in harmony to their design specifications.

Case Study

Dakro have recently completed a major air system commissioning project at a large hospital in the UK Northwest. The project required us to pre-commission clean all serving ductwork followed by a proportionately balance all AHUs for all the specific circuits.

As part of the project we followed CIBSE (Chartered Institution of Building Services Engineers) Codes of Practise and HTM (Health Technical Memoranda) recommendations checking everything from air leakage tests, regulating dampers, cleaning of fans and filters to ensuring design volumes (terminals) are achieving designed flow rates.

Each serving critical room must have either a positive or negative pascal rating which calibrates the pressure.

Finally, the rooms are signed-off when they receive their Calibration Certificate, Test Pack Reports and it is signed-off by the consultant engineer. The Calibration Certificate evidences the measurements of room temperature, relative humidity, barometric pressure (mbar) using a micromanometer/barometer.

We were delighted the client was very happy and on the back of this and we've been asked to air system commission a further four surgical theatres.
