Flu gases flowing through the stack will create lot of noise. Stack silencers are essential in controlling noise produced in industrial stack exhaust systems. PR Acoustics Stack silencer will reduce the noise with a very minimal pressure drop across the silencer (20-50mm of water column as per customer requirements). For quick installation, we can supply stack silencers as stack inserts that can be attached to the base or top of stacks. Every stack silencer is custom designed based on Acoustic targets, flow requirements, pressure drop, discharge velocity and temperature of the medium.
