CORRESIC® Compact Sealing System
• Sealing face in thermally resistant
sleeve > no creeping at high
temperatures
• No sinkings for sealing in tube sheet
> more compact bundling of tubes
means up to 35% more transfer area
> strengthened steel core for better
stability and therefore…
• Compact sealing system with double
sealing as standard > minimised risk of
cross contamination
• …fixing of the tube sheets only by outer
pitch circle > no corrosion risk by coated
screws compressing the tube sheets

CORRESIC®-SE Applications
• Liquid/liquid heat exchange at all acids, brines and
organic solvents, e.g. mixed acid, sulphuric acid,
nitric acid
• Reboiler evaporation, especially steam heated
• Condensation processes with special need of
robustness
• Pickling applications in steel and galvanic
industries (heating, cooling, acid regeneration)
• Acid concentration processes
