Silenced chimney for new wool mill






ROCKWOOL is building a new wool mill in Neuburg an der Donau. Nießing was commissioned with the construction of the largest chimney of this new plant. The 75 m high chimney with a diameter of 3.6 m conducts almost 500.000 m³ of exhaust air per hour into the open air. The chimney contains a special silencer which is designed as a plate absorber.


The plate absorber dampens the noise of the large centrifugal fan to the legally required level. ROCKWOOL deliberately chose the Nießing plate absorber as silencer because the Nießing in-house development has already been able to convince with its performance in a large number of plants.
