In 2009 , PowerQ conducted an Electromagnetic Field survey emitted from crystal growth furnace to find out level of interference that caused to damage several Fan Filter Unit (FFU) at new Wafer plant, Tampines , Singapore.
Enginners from PowerQ installed EMF data logger to measure and monitor with data logger to generate a clear picture of EMF emissions in the areas over time and capture any peak values. The data was recorded for several weeks and at interval of 1 mnute undered varied operating condion . PowerQ provided observation status and re-measured EMF after the proposed measures had been implemented to analyze the collective information of EMF interference bymminimum and maximum field strength readings.
