An Acoustic louver for Chiller is designed to control the noise of any sealed unit and whenever it is designed for cooling, it allows good air circulation and helps to get rid of the heat. Most chillers resonant sound production takes place in the low and middle frequencies within the building. It is in these frequencies that noise generated outside the building can be unacceptable. And, acoustic louvres are the one-way barricades that deflect the propagating sound energy after they have absorbed it.
