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 bolting of other conventional 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 for a relatively thin channel design (no edge bending due to bolting) with consequent reduction in the exchanger’s size and weight.

LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchanger is not just a common screw-plug closure system.

Our unique design of the LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchanger internals offers exceptional maintenance advantages over any competitor’s screw-plug closures:

  • Avoid deformation of the internal bolts
  • Avoid overstressing of internal push bolts
  • The seal gasket, confined into the diaphragm, follows the relative movement of the diaphragm with respect to the channel due to differential thermal expansion, thus guaranteeing the sealing even during transient conditions
