when the flow rate permits the use of one half of the shell at a time. In heat recovery
applications, or where the application calls for increased thermal length to achieve effecti v e
overall heat transfer, shells can be installed with the flows in series.
Up to six shorter shells in series is common and results in counter-current flow close to
performance as if one long shell in a single pass design were used.
TEMA G and H shell designs are most suitable for phase change applications where the bypass
around the longitudinal plate and counter-current flow is less important than even flow
distribution. In this type of shell, the longitudinal plate offers better flow distribution in vapor
streams and helps to flush out non-condensables. They are frequently specified for use in
horizontal thermo-siphon re-boilers and total condensers.
