    Event Air-Conditioning Hire in London for an Athlete’s Tunnel at the o2 Arena


    The Challenge;

    Event air-conditioning hire in London for an Olympic project that was specified and delivered at short notice for the games.

    ACS were contracted by Nussli Switzerland to supply an air conditioning hire system for a temporary structure- a tunnel was built to allow athletes covered air-conditioned access from the training area to the arena. As always, this project needed delivering quickly.


    The Solution;


    Different air conditioning hire systems were looked at for the tunnel cooling including, split PAC, ducted air, and internally fitted air handling systems. It was decided that internally mounted water cooled AHUs would provide the most cost effective cooling system.

    Four 20kW AHUs were installed with a 150kW chiller as base plant for the tunnel cooling system. Reinforced rubber hose with Cam-loc connection system was used for water distribution.

    Temperature control was adjustable locally at the air handling units giving the client complete control over the internal climate.

    The system operated though-out the games remaining reliable at all times. No call backs were needed to this system.




    This type of system is very compact and powerful. The air handlers can be installed directly into the areas requiring cooling. Their high cooling capacity, small footprint and pleasing aesthetics suite them perfectly to this type of work.

    The chilled water system was designed to be maintenance free due to limited access during the games. An oversized expansion vessel was fitted to maintain pressure in the chilled water system for the duration- reliable, low maintenance air conditioning hire.
