Exothermics’ DSP Dimple Plate Heat Exchangers are fully-welded and can be manufactured in a wide variety of sizes. They can also be configured for counter-flow or cross-flow operation. In these exchangers the parallel plates are formed with either staggered or inline dimple patterns to reduce the potential for particulate fouling. The Dimple Plate Heat Exchanger can recover energy from an industrial exhaust with temperatures up to 1,200° F (650° C). The dimple plate design can be used for applications where the flows may include some particulate.
