- There is no need for hydraulic sioning devices to remove the channel cover and
reassemble the exchanger, thus eliminating the number of tightening cycles and strain gauge

- Avoid deformation of the intemal bolts,
- Avoid overstressing of intemal 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.
