Title:
DEVICE, METHOD AND PLATE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2014/086677
Kind Code:
A3
Abstract:
A device (22) and a method for assessing a gasket pressure of a gasket arrangement (12) between two adjacent heat transfer plates (10) of a plate heat exchanger (2) is provided. Further, a plate heat exchanger provided with a device like the one above is provided. The gasket arrangement seals between said adjacent heat transfer plates to define a flow channel between said adjacent heat transfer plates, and said gasket arrangement is arranged to be exposed to a fluid passing through the flow channel. The device is characterized in that it comprises a test object (26) and a holding means (54) which are adapted to be arranged in a flow path (F) of said fluid. The holding means 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 (13) 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.
