A device and a method for assessing a gasket pressure of a gasket arrangement between two adjacent heat transfer plates of a plate heat exchanger is provided. The gasket arrangement seals between adjacent heat transfer plates to define a flow channel between adjacent heat transfer plates, and the gasket arrangement is arranged to be exposed to a fluid passing through the flow channel. The device comprises a test object and a holder which are adapted to be arranged in a flow path of the fluid. The holder is arranged to hold the test object and the test object is arranged to be exposed to the fluid. The device is adapted to be arranged outside a space delimited by the adjacent heat transfer plates. The test object is arranged to be evaluated for an indirect assessment of the gasket pressure of the gasket arrangement.

Device, method and plate heat exchanger

A heat exchanger plate, where the plate is provided with a heat transfer surface having a corrugated pattern with a plurality of ridges and valleys, and where the heat exchanger plate is provided with a plurality of guiding sections, and where each guiding section has a first guiding surface and a second guiding surface, where the first and second guiding surfaces are perpendicular to each other. A heat exchanger having a plurality of heat exchanger plates is also disclosed. The advantage of this heat exchanger plate is that it allows for an improved alignment of the heat exchanger plates.

Heat exchanger

The invention refers to a plate heat exchanger, which includes a sensor device and a plate package of heat transfer plates (). The heat transfer plates form between the plates () first passages () for a first fluid and second passages () for a second fluid. The sensor device includes a space (), which is closed to the first passages () and the second passages (). The closed space () is arranged to contain a medium, which can be influenced by the temperature of at least one of the fluids, and to be connectable to a device () for sensing a pressure change of the medium in the closed space (). The closed space () is at least partly defined by at least one of the plates ().

Plate heat exchanger

A device for treating a substantially gaseous medium includes a number of parallel plates ( ) which are connected to each other and provided adjacent to each other in such a manner that they, via port holes in the plates ( ), form a first channel ( ) and a second channel ( &prime;). The first channel ( ) is arranged to transport the gaseous medium, and the second channel ( &prime;), which is separated from but in heat transferring contact with the first channel ( ), is arranged to transport a cooling medium for cooling the gaseous medium. At least a part ( ) of the first channel ( ) is arranged to separate liquid from the gaseous medium. The part ( ) of the first channel ( ) is formed by a plurality of plate interspaces between a part of the plates ( ), wherein at least one of the plates ( ), delimiting one of the plate interspaces, is arranged to be passed by the gaseous medium on both sides thereof.
