Successfully used for many years, the LUMMUS ADVANCED BREECH-LOCK EXCHANGER® Heat Exchanger features a special threaded ring to hold the channel cover and contain channel pressure. This unique and innovative technology eliminates the large channel cover flange and heavy bolts of other conventional high-pressure exchanger designs.
The hydrostatic pressure load is taken by the channel body and not by heavy bolting (bolts are only sized for gasket compression loading). This allows an optimized design of the channel (no flange or channel distortion due to bolt tightening) with consequent reduction in the exchanger’s size and weight.
