Complete building services portfolio in operation for the multifunctional building complex of the future.

KSB products are often working away reliably in the background. However, in the case of this particular project, it’s worth taking a look behind the scenes. In Mannheim’s new multifunctional building complex “Das Quartier Q 6 Q 7”, an array of KSB products help to ensure a reliable infrastructure. Over a space of around 153,000 m² in which shopping and residential areas have been created as well as a hotel and restaurants, we have put our entire expertise in building services into practice – from drainage and water supply to heating, air-conditioning, ventilation and fire-fighting water supply.
