Hairpin heat exchanger
Brown Fintube Europe

Hairpin heat exchangers utilize true counter-current flow which maximizes the temperature differences between the shellside and tubeside fluids, unlike the multi-pass shell-and-tube designs where correction factors are used to account for the inefficiencies resulting from co-current passes.

When your process calls for a temperature cross (when the hot fluid outlet temperature is below the cold fluid outlet temperature), a hairpin heat exchanger is the most efficient design and will result in fewer sections and less surface area.

Double-pipe heat exchangers use a single pipe within a pipe design and are commonly used for high fouling services such as slurries, where abrasive materials are present, and for smaller duties. Standard shell diameters range from 2" to 6".

Multi-tube heat exchangers are used for larger duties with standard designs established for shell diameters up to 30" with surface area in excess of 10,000 ft2 per section.

Brown Fintube has a variety of unique enhancement devices for different process conditions.
