While working on their web site development, Pro Economy also wanted a short animation to show their Orca Leggionella treatment system, which was to be a feature on their exhibition stands at various shows and be available for download on the new web site.

The video takes the viewer though the mechanics of the system and then goes onto the molecular level to show the Leggionella bacteria themselves and how they are ultimately destroyed by silver and copper ions produced by the Orca system.
