We launched the PasTest 2000, a non-destructive leak detection testing service for pasteurisers and plate heat exchangers, a few years ago to address a critical need in the market. This need was to be able to detect leaks without opening the plate pack.
The PasTest 2000 is a patented testing method which can rapidly detect small leaks in plate heat exchangers without the need to open the plate pack. It has been tested by Campden BRI, the UK’s leading independent food and drink research organisation. Periodic testing using the PasTest 2000 system will reassure customers about the integrity of their plate heat exchangers, and could reduce the possibility of a product recall where product is heated or cooled by a plate heat exchanger. This rapid, accurate test allows several heat exchangers to be tested in a single day which will reduces production downtime.
PasTest 2000 uses only the local water supply which is pressurised and pumped through the high pressure side of the plate heatexchanger at a measured temperature. No saline, compressed air, or chemicals are introduced into the plate heat exchanger during the test. The hand-held PasTest2000 unit accurately measures any change in pressure within the closed low pressure side, and any increase in pressure rapidly indicates the presence of a plate defect.
The PasTest 2000 produces rapid, accurate results and will provide our customers with the peace of mind and the necessary documentation that their heat exchanger plates are without defect, and can reduce the possibility of a product recall.
