Heat Exchanger Testing with Pastest+

What is Pastest+?

Pastest+ is a non-destructive integrity test and holding time verification system for pasteurizers,  plate and tubular heat exchangers.

Developed & Patented by Unison & Validated by Campden BRI, the UK’s leading independent food and drink research organisation, Pastest+ is transforming process equipment testing worldwide, resulting in substantial cost and time savings.

 

How does Pastest+ work?

Unison’s service engineers run a test on your plate or tubular heat exchanger using the Pastest+ app and system. Our specially designed system allows us to do this without dismantling any plates and using only process water.

Capable of detecting small cracks to an accuracy of 50μs, Pastest+ technology detects pressure increases in a closed volume of the plate heat exchanger. If a crack is detected, this will be shown on the Pastest+ app, and a further inspection of the plate pack will be required.

Following the test, a QR code is generated and printed on a label which is attached to the heat exchanger. Using this QR code, you can easily view the automatically generated test result details, which prevents any operator manipulation of the final results. No more handwritten results.

The Pastest+ app automatically sends all of your results to your designated email, providing personalised access to your equipment test data. At the same time, it also saves a complete service history of all your PHEs within the app.

Simplify Your Heat Exchanger Testing

Pastest+ is the only system on the market that can do an integrity test and holding time verification test simultaneously. Now, you no longer need to worry about costly production downtimes as Pastest+ makes time-consuming defect detection a reliable and faster process taking only 1-15 minutes depending on the size of the equipment. This means that several of your key heat exchangers can be tested and back in production quicker than ever before.

Our system only uses the process water supply, thus preventing any saline, compressed air, or chemicals from contaminating the plate heat exchanger during the test.

Pastest+ versus Other Testing Technologies

  • Specifically designed for heat exchangers rather than repurposed.

  • Quick – process typically takes a few minutes.

  • Only uses process water to detect cracks as small as 50 microns. No saline, compressed air, gases, or chemicals are introduced into the plate heat exchanger during testing.

  • Immediate results, which greatly reduces downtime.

  • Campden BRI-validated.

  • Comprehensive test and service history of each user’s PHEs stored directly in the Pastest+ app.

  • Test certificates generated automatically.

  • Features an integrated, fully-automatic holding time verification facility.

  • Results generated in the newly-launched Pastest+ app.
