- Counter-current flow configuration maximizing the temperature differences between the shell side and tube side fluids (result is less heat surface needed compared to multi-pass type).
- When the process calls for a temperature cross, a hairpin exchanger is the most efficient design.
- Reduced sizes of pressure vessels and consequently lower equipment costs (exotic materials).
- Separate tube sheets handle high temperature differences and cycling more efficiently than shell & tube
- Tube side and shell side connections are on the same end for ease of installation and piping.
- Modular design allowing future duty changes.
- Easy maintenance operations.
- Longitudinal fins may be used to provide extended heat transfer surface with relatively low resulting pressure drops.
- Range: from 4 to 24 inches shell diameter.
- Separated or unihead type closures.
- Our separated head closure type (1 gasket shell side, 1 gasket tube side) is particularly suitable for high pressure up to 700 bars tube side and 200 bars shell side.
- It is recommended for high temperature and avoids all risks of contact between the two process fluids.
- Our unihead type is less expensive and can be used in moderate services.
