Technical equipment The Convention and Executive Education Center has numerous different types of technical equipment for presentations. Standard equipment in all plenary halls comprises beamers, overhead projectors, flipcharts and public address systems. All the equipment is controlled with a touch panel from the speaker's table. The technical support provided by our Janitorial Services is one of our strong points. During events, a helpline is available to organisers and speakers, so that support can be quickly and reliably requested.
