Silencers for Screw Compressors

Screw compressors can generate significant pulsation at multiples of vane pass frequency.  Since this pulsation occurs at relatively high frequencies, shell wall and piping natural frequencies can be excited.  EDI designs silencers for screw compressors using our pulsation simulation software.  Designs are developed to minimize the effects of cross-wall resonances, while obtaining acoustic filtering.
