Very gentle cleaning with air bubbles
Sintef has recently tested wear and tear during high pressure, low pressure and cavitation.
Quote from Sintef report:
…After 35 cleaning events, on average 82% and 90% of the Notorius A and Notorius 3 coating, respectively, were damaged (Figure 7). Low-pressure cleaning damaged on average up to 9% after a single cleaning event and up to 46% after 35 cleaning events. In contrast, a single cavitation cleaning event had no measurable effect on the coatings (average damage 0%, maximum 2%)…
This means, after 35 cleanings, with impregnation Notorius A:
- High pressure, 220 bar, 220L, 82% wear
- Low pressure, 80 bar, 120L, 46% wear (increases with more water)
- Cavitation cleaning 200 bar 2% wear
It was so majorly to cavitation cleaning that even we were surprised.
With a cleaning interval of 10 days 35 cleanings is enough for a whole year.
This is nothing when during the same period approx. 50% disappears without cleaning during the same period.
