U-Turn

U-Turn is a liquid separator especially designed for use with plate heat exchangers in ammonia applications. The module – including the separator and plate heat exchanger ensures minimum pressure drop losses and maximum energy efficiency.

Alfa Laval U-Turn is designed to utilize the very best from Alfa Laval’s plate heat exchanger technology. Installed above, the self-contained U-Turn can be easily mounted onto the compatible plate heat exchanger. It can cover ammonia capacities from 200 to 1400 kW at 0°C evaporation temperature and from 50 to 500 kW at -40°C evaporation temperature.

The module provides an effective and compact installation with less vertical rise and smaller overall dimensions than any other solution.

Main design features

 

  • 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

Ready to install

 

The U-Turn module is delivered within short time, due to standardization. It is a fully functional module from one supplier and carries the CE-stamp, as well the approval from PED (Pressure Equipment Directive).

How it works

The U-Turn module is opening a new chapter in evaporation. To see why and how it works, please read the main characteristics and watch our video at the bottom of the page

  • 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.
