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 will often be be 60-80% smaller than shell and tube exchangers for  similar services. Tighter minimum approach temperatures will improve overall process efficiencies and total cost of ownership as well.

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.
