Unique Design and Advantages of the OCAP™

"Floating" plate pack handles cycling applications with ease

OCAP units feature a non-welded, "floating" plate pack contained within a rigid housing. This design permits thermal expansion and contraction with minimal stress on the unit’s components. A patented compression strip assembly provides a tight metal-to-metal seal. This design reduces stress and extends the life of the OCAP.


The OCAP offers many other benefits over conventional exchangers:

  • Generous plate clearances
  • Ability to inspect and clean both sides of the exchanger
  • No tubes to vibrate or to cause acoustic resonance
  • Floating plate pack to handle differential thermal expansion
  • Modular design can accommodate future incremental capacity increases
  • Modules are transportable, allowing top-quality shop fabrication, eliminating costly field fabrication
  • Compact space-saving geometry
  • Rigid heavy-duty frame assembly
  • Material "mix-and-match" construction
  • Ease of installation
  • High efficiency
  • 10% - 15% less weight
  • 30% - 40% smaller size

Cold End Insulator™ technology prevents cold corner condensation

In certain cases where the flue gas contains a significant amount of sulfur, the first pass (the "cold-end" of the preheater) can be constructed to contain our proprietary Cold End Insulator (CEI) technology. This simply increases the heat transfer plate metal temperature in the cold corner of the air preheater, resulting in a condensation-free operation of the OCAP exchanger.
