Dosatron D25 D25RE/IE5 (PVDF)
Connected to the water mains, the Dosatron uses water pressure exclusively as the driving force. In this way, it draws in the concentrate, doses it to the desired percentage and mixes it with the drive water. The working solution produced in this way flows through the Dosatron. The amount of product added is always proportional to the water flow rate, even in the event of fluctuations in flow rate or pressure..
