For dosing agent containers of 20 liters. The mineral dosing devices BWT Bewados are used for dosing active substances and significantly prevent damage caused by lime and/or corrosion in water pipes and connected devices. With every water withdrawal, the BWT Bewados dosing devices dose less than 0.005 g (5 mg/l) of the mineral combination Quantophos/Impulsan per liter. This reacts with the inner walls of the pipes and forms a thin but firmly adhering protective layer (internal pipe sealing) that separates the water from the pipe. Existing rust and corrosion spots are encapsulated and rendered harmless. Compact mineral dosing device including connection module and suction lance in one package. Available with connection nominal sizes of 1" (DN 25) or 5/4“ (DN 32). Delivery does not include the 20l box of Quantophos. In the 1" variant, the Bewados E20 dosing device is suitable for connection to the softening systems AQA smart and AQA solar. Electronically controlled mineral dosing device with integrated diagnostic system. After the dosing agent has been consumed, the device automatically shuts off (built-in level monitoring).
