Plate-fin Kettle Exchangers

The CoreWorks custom-designed Plate-fin Kettle (PFK) exploits all the benefits of a CryoCore® brazed aluminum heat exchanger (BAHX) and integrates it into a kettle reboiler design. The PFK provides a compact configuration, custom construction options, and higher performance than traditional shell-and-tube exchangers and thermosyphon assemblies.

PFKs pack performance in space-saving construction - CoreWorks PFKs are 60-80% smaller than typical shell and tube exchangers for similar services. Tighter minimum approach temperatures improve overall process efficiencies and lowers the total cost of ownership over the life of the project.

That’s why we are the preferred service provider for major facilities around the globe.

A specially configured CryoCore (BAHX) is partially submerged in a refrigerant bath. The vessel is sized to minimize liquid entrainment and carryover. For the most demanding applications, mist eliminators can be utilized to limit entrainment even further.
