Retrofit: Airport terminal lounge

At an airport in Germany, an old belt-driven fan was replaced in a air handling unit. The new ECFanGrid fans control an air volume of 50,000 m³ per hour in the relevant public area of the terminal. The ECFanGrid control cabinet system acts as a central connection point for all fans. In addition, there is a more efficient and uniform flow to downstream components such as filters and heat exchangers. Furthermore, the baffle plate of the belt drive fan has been eliminated, which significantly reduces pressure losses. With a 44% increase in energy efficiency, approximately 40 tons of CO2 can now be saved annually. The fan could be replaced within only five days. The payback period for this retrofit example is only 2.3 years.
