pump does not operate; for flow rates exceeding the peak flow rate the dosage of AcquaSIL 20/40
reduced. As a consequence, the overdosage of AcquaSIL 20/40
®
20/40 in the tank is not signaled by any automatic device, but it is visible from the emptying and crushing of
the tank itself. Check the tank filling degree periodically. When the filling degree drops below the minimum it
is necessary to refill the tank. A prolonged dry running may cause a temporary blockage of the pump (see A3
troubleshooting); moreover, the missed dosage of AcquaSIL 20/40
against scale and corrosion.
A1.6 What's AcquaSIL 20/40
®
AcquaSIL 20/40 is a ready-to-use (do not dilute) aqueous solution of food grade sodium polyphosphates
used to prevent incrustation and corrosion.
Anti-scaling effect: AcquaSIL 20/40
formation of scale deposits.
Anti-corrosive effect: AcquaSIL 20/40
heat exchange phenomena, but it is very efficient in protecting the metal surfaces from corrosive
phenomena.
®
Keep AcquaSIL 20/40
ranging from 5 °C and 35 °C. Keep out of the reach of children.
