Phillips and Temro’s silencer division has been providing exhaust noise solutions through our COWL and EM brand silencers for many decades. We have the in-house expertise to evaluate applications and offer solutions to meet/exceed customer requirements. We work closely with our customers in finding the most cost effective solutions to their noise problems.

 

We understand the challenges to predicting noise accurately. Over the years, our empirical models have been developed to better predict the performance of our silencers. We have the capability to use FE (Finite Element) and CFD based numerical simulation tools to optimize the performance of our silencers. With emphasis on quality and fast turnaround, we have helped our customers meet some of the toughest specifications in the industry. We are committed to research better ways to predict performance, extend service life and improve performance of our products.

Our COWL series silencers are well known for providing industry best attenuation, in a small envelope. The “Disk” style silencers, both cylindrical and rectangular, have proven to be very effective designs in space limited applications. With options to add such as Spark arrestor, Catalysts, Insulated construction, we offer products to cover the whole range of engine based applications.
