Cain Industries - Model HRSA Series - Heat Recovery Silencer - Axial

The HRSA Series waste heat recovery silencers are compact cylindrical heat exchangers designed for either dual or single exhaust small engines (15 -150 kW). In addition to lowering exhaust noise, the unique coil-type configuration and optional circulating pump allow for a secondary circulating liquid flow system. The 1” NPT interconnecting piping, within a main liquid flow loop, provides for simple and less costly piping modifications. HRSA models are available to accommodate entering gas temperatures from 400°F up to 1,600°F. The required heat transfer surface, coupled with a small diversion of the main flow, adequately recovers desired BTU/hr which lowers the outlet gas temperature below 250°F as required. The optional internal stainless gas bypass also allows tempering of the exit temperature if required.
