In a plate heat exchanger a package of heat transferring plates (1) is kept together between two end plates (2, 3) by means of two or more threaded bolts (7) and nuts (9) in threading engagement therewith. A motor (29) is arranged through an endless drive member (28), such as a tooth belt or the like, simultaneously to rotate all the bolts (7) or all the nuts (9). The plate heat exchanger thereby may be rapidly, simply and safely opened and restored for operation in connection with inspection and/or cleaning of the heat transferring plates. |
