Pressurisation device for a bundle of plates (1), in particular a plate heat exchanger, where the bundle of plates is put in a sealed chamber (2) containing parallel layers of metal plates (3) forming a first circuit A for a first fluid under pressure and a second circuit B for a second fluid under pressure. The first fluid is at a greater pressure than that of the second fluid. A first pipe (15) connects the chamber with the inlet of the first fluid (10) which feeds the chamber constantly, a second pipe (16) connects the chamber with the inlet of the second fluid (12) which feeds the chamber when the first fluid stops, and the inflow of the second fluid is controlled by a controller (20). <IMAGE> |
