In COILS usually the airflow flux is only orthogonal to the frontal area with one pass:



In COILS software you can set baffles to configure the airflow fluxes.



If you set at least one baffle, an additional menu will appears and you will can configure the airflow flux in 2 ways:



1- Orthogonal LxH: in this case the flux will be orthogonal to the length and height of the coil exchanger:



2- Orthogonal LxB: in this case the flux will be orthogonal to the length and depth of the coil exchanger:
