Over the past 40 years, brazed aluminium plate-fin heat
exchangers (BAHXs) have become the preferred type for a variety of specialised
and general applications, mainly as a result of unique capabilities in heating
and cooling liquids and gases, and boiling and condensing with single and
multicomponent streams. Users can benefit from their
- Exceptionally small size, weight and footprint which
saves installation and space costs.
- Very large surface area per unit volume combined
with high heat transfer coefficients thus giving an outstanding thermal
performance from a small exchanger.
- Ability to handle tiny temperature differences
between streams thereby reducing compressor power and giving improved
reheat.
- Ability to accommodate many streams in the same
exchanger thus giving greater flexibility in process flow-sheet design and
in process integration.
- Small fluid inventory with consequent improvements
in control, safety and product quality.
