Julio C Nazario, Borin-Chem Industrial Services, Inc.:

Everything is working out fine with our new stainless steel passivation tester; The Passi-Flash 3036. Our company is already highly ranked with our customers base; but when we added the new feature of printing out our logged data to our certification package our product credibility and customer confidence in our procedures was truly unquestionable . Much thanks to the Passi-Flash 3036. Keep on making great inventions like this one.

Peter Girten, Stone Brewing Co.:

I’ve been speaking with other brewers, and everyone should know about the 3036. We are very pleased with the PassiFlash 3036 thus far. We’ve been looking for a way to test passivation without using copper sulfate solutions, as we don’t want to have any of this inside of our tanks, and we don’t have a way to perform a salt spray test on the interior of our tanks. I did perform a few tests on some scrap stainless stock we had laying around – the results using the 3036 were consistent with the results from the copper sulfate tests.

We are now using the tester for every new tank we install to verify our passivation techniques, and we are also using the tester to determine how long the acid cycle of our tank CIP procedure really needs to be. We also discovered our acid cycles were inadequate for new tanks – we found that immediately after an acid cycle, a rinse, and drying, the surface would read unpassivated. After 4-8 hours, however, the surface would read passivated. Our nitric acid concentration was too low and/or our cycle time was too short. The procedure was sufficient to remove free iron from the surface, but we were not completely forming a chromium oxide layer – air was completing the process for us.
