Coolant passes
Depending on the coolant reversing cover, the coolant is passed through the pressure vessel either 3 or 6 times.
On the same reversing cover, it is possible to choose between 6 pass or 3 pass - depending on the positions where
the coolant pipes are mounted.
Fig. 7: Coolant pipe connections for OW781(B) .. OW941(B): 6 or 3 pass is possible at the same cover, depending on he connection
