Plate heat exchangers
Using a modified version of Belzona Know-How System Leaflet GSS-9, a plate is coated with Belzona® 9411 and used to form a thick layer of Belzona 1341 on the end cover. This procedure provides a perfect finish and excellent seal.
The first application was undertaken in 1994 – following the successful trial this specification has been extended through all plants in the group. This particular example was carried out in July 1999.
