Liquids dosing unit AlfaDos™

gravimetricautomaticvacuum

Like a traditional dropping funnel, the innovative AlfaDos™ dosing system is simply driven by gravity and does consequently not require any pumps. Thus, the problems are eliminated which always occur in the case of pumps, such as media incompatibility, suction problems or bubbles. In addition, this results in a considerable cost saving, no costly balances and pumps are required. The flow is controlled by a solenoid valve. As no measurement and no regulation of the flow takes place, the dosing rate is not constant. However, in some cases, such as for the pH value control, the maintenance of a certain dosing rate is not so important. Here AlfaDos™ is the absolutely most inexpensive solution. • Simple dosing functions • pH value control • Redox control • Titration • Dosing, subject to the size of the process involved • Inexpensive • Compact and robust • Does not require pumps • Resistant to aggressive media • Easy to clean An AlfaDos™ system consists of a glass stainless steel or plastic storage vessel. Outflow takes place by gravitational force or applied pressure and is controlled via a solenoid valve. Dosing under pressure or vacuum is possible if a pressure compensating line is installed. Traditional dropping funnels or dosing devices with pumps and balances are replaced by AlfaDos™ if the requirements for a constant dosing rate are low or the dosing is regulated based on another variable, for example the pH value or the Redox potential, or if a process signal such as the temperature is used as a controlled variable.
