ABB drive makes British Airways Flight Simulator quieter
16 September 2013
British Airways Pilots are benefiting from a quieter Flight Simulator environment following the installation of ABB drives in an Air Handling Unit (AHU) at the their Flight Training Centre near London’s Heathrow Airport.
The AHU is used to cool the flight deck and instruments on one of their Boeing 777 Flight Simulator’s. Previously the AHU’s fan motor was run at constant speed but generated high noise levels. By using a 5.5 kW ABB HVAC drive at 39 Hz, the same flow rate can be obtained at a lower motor speed, resulting in a reduction in noise from 80 dBA to 73 dBA.
