The Prime Tower (or ‘Maag-tower’) in Zurich is a 126 metres high tower and counts as the highest skyscraper at this moment in Switzerland. The tower is located near the Hardbrücke railway station and replaces an industrial facility that has been demolished.

The construction of the building and the surrounding complex started in 2009 and consists of different parts; Cube, Diagonal and Platform. The Prime Tower is mainly used to facilitate offices. The octagon-shaped building is the winning project of a high-class competition involving top-ranking architects. Construction will be completed in 2012.

The Prime Tower received the LEED gold environmental label and the Minergie© green property label, the seal of approval by Credit Suisse AG for sustainable real estate.

The designer of the Prime Tower is well-known in Europe because of his design of the immense tower of Deutsche Bank in Frankfurt, Germany. The main goal for investor Swiss Prime was to create an energy efficient building through the use of radiant cooling and heating ceilings.

A record amount of 10.000 AB-QM valves with matching AME actuators were installed to create optimal balance and control in heating and cooling in the tower. To this day this is the one of the biggest projects within Danfoss Heating Solutions and the business area Hydronic Balancing and Control.
