In plate heat exchangers the dismantling of the pack of plates is a lengthy job which normally has to be carried out in situ. A plate heat exchanger has a frame including a head (3), a supporting pillar (7) and a movable follower (4) mounted on a top rail (2) extending between the head (3) and pillar (7) which also carries the plate pack (1). In accordance with the invention, the top rail (2) is readily releasable therefrom by bolts (13) whereby the whole plate pack (1) may be lifted clear of the frame. The follower (4) may be temporarily accommodated on the supporting pillar (7) by clamping means (10) and the roller (5) removed. The top rail may be provided with means for attachment of lifting shackles (11).
