Improved sealing makes this heat exchanger more efficient

Thanks to a patent-pending sealing concept, the new Compabloc+ heat exchanger (photo) ensures safe operation with no risk of media leaks at pressures up to 60 bars — representing a 20-bar increase over previous Compabloc models. The sealing concept is a first-of-its-kind for bloc-type heat exchangers, featuring a fully-confined graphite gasket, rather than a traditional flat gasket. This change makes it possible for Compabloc+ to safely handle higher operating pressures than possible in the past, while simultaneously simplifying maintenance by protecting against overtightening and creeping. Compabloc+ is a more energy-efficient alternative to traditional shell-and-tube heat exchangers and can replace up to four shell-and-tube units for the same duty, according to the manufacturer. — Alfa Laval AB, Lund, Sweden
