Chlorine Gas Metering Systems DULCO®Vaq
In the metering system DULCO®Vaq, chlorine gas is safely handled under a vacuum. The negative pressure generated in the injector opens the vacuum dosing regulator fitted on the chlorine gas tank and the chlorine gas enters the water to be treated. Adjustment valves control the metering volume and flow meters precisely indicate the chlorine gas flow. A large number of individual configurations is provided for by the use of additional components, such as motorised control valves, injectors or vacuum switch-overs.
ProMinent DULCO®Vaq components are used for large-scale chlorine gas systems for applications in industry and the treatment of large volumes of water. Additional components, such as evaporators, pressure reducing valves, pressure switch-overs, metering systems and corresponding room equipment.
ProMinent experts consider the latest safety requirements when designing systems for specific projects.
