- the increase in the number of rows 41 of tubings allows the second heat exchanger 20 to approach a real heat exchanger against the current.
- the heat exchange is only more favorable and increases the performance of the heat exchange system 1.
- the use of the fan-exchanger unit 60 with a slip-type heat transfer fluid would, because of the existence of a sliding, reduce the nip, that is to say the minimum distance between the two fluids exchanging.
