  4. Renovation of an AHU in a large auditorium

Renovation of an AHU in a large auditorium

Wednesday 22 December 2021

Air handling unit renovation projects are becoming more and more common. It has been proven that replacing the old belt-driven fans with modern EC FanGrids saves up to 70% of the energy consumption for air conditioning in a building. In addition, ECFanGrids are also used in new projects.

Retrofit project with an EC FanGrid in 3x3 layout with five fans Retrofit project with an EC FanGrid in 5x4 composition

 

For example, a major retrofit project was carried out in an auditorium for large events in southern Germany. A total of 16 new retrofit kits of various compositions, ranging from 1x1 to 5x4 EC FanGrid, have been installed. They support an airflow of 5,100 m3/h up to 88,000 m3/h.

Other advantages of the AHU renovation, apart from the energy saving due to its inherent efficiency, are its easy installation and maintenance, or the design flexibility, for example.

At Airtècnics, we are specialists in the highest customisation for the projects entrusted to us and a team of specialised engineers will provide solutions totally adapted to the client's needs. Contact one of them to advise you.
