GCAP CoolCast: Garden City Ammonia Program

Alfa Laval donates U-Turn Heat Exchanger to GCAP

This last week in San Antonia Texas, Alfa Laval was showcasing their partially flooded U-Bend / U-Turn plate and frame heat exchanger.  Since ALfa Laval showcased this a few years back the crew at GCAP has had to have one.  Danny Hauenstein made it happen this week and it’s is getting shipped to Kansas.  We have saved a special place for this unit in the hopes getting one for the training lab.


  • Compact dimensions
  • Shorter height and length allowing installation onsite without dismantling
  • No additional support is needed, as the U-Turn separator is supported entirely by the plate heat exchanger
  • Easy maintenance, as both sides of the plate heat exchanger are fully accessible.
  • All ammonia connections access the same side which makes installation easy
  • Integrated oil drain
  • Stainless steel ensuring corrosion resistance and no need of surface treatment

  • It ensures efficient separation – due to the use of four different
    separation methods.
  • The short vertical ammonia driving columns, allowing small
    temperature approaches and high system efficiency.
  • Sliding support allows thermal expansion, ensuring no
    thermal tensions build up.
  • Significant oil pot volume in standard execution enough
    for manual drain
  • Separation based on droplet size 0.15 mm
  • Margin for separation is 25% plus one nominal diameter
  • Maximum separation gas velocity is restricted to 60% of
    the re-entrainment velocity, avoiding liquid brought back
    to the gas flow.
  • Extra safety margin from 180° U-bend.
