Abstract
(EN)
The present invention relates to a plate heat exchanger for treatment of a feed. The plate heat exchanger including a plate package forming alternating first and second plate interspaces. Each first plate interspace defines a condensation section defining an upper border, a lower border, an inlet and an outlet. Each heat exchanging plate being provided with ridges and valleys extending in opposite directions. The condensation section defines a passage extending at least a part of the distance between the upper border and the outlet. The ridges of each heat exchanging plate outside the passage extend to a contact plane allowing opposing heat exchanging plates to abut at contact points in the contact plane, whereas the ridges of each heat exchanging plate within the passage are spaced apart from the contact plane preventing contact between opposing heat exchanging plates in the passage.
