With the DULCO®Vaq, ProMinent offers a vacuum metering system for chlorine gas that combines safety with efficiency. The system is designed for disinfection of drinking water, swimming pool water, waste water and cooling water and ensure impeccable, germfree water quality.
The systems are available in performance classes from 0 to 200 kg/h and are compiled as a complete solution from high-grade, tried-and-tested standard components. This increases the system’s durability, while at the same time reducing both operating and maintenance costs.
DULCO®Vaq is designed as a full vacuum system and therefore offers maximum safety for users. The vacuum generated in the injector opens the vacuum metering controller 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 additional components, such as motorised control valves, injectors or vacuum switches.
Exact control electronics and measuring technology ensure efficient chlorine gas metering during both manual and automatic operation. Uninterrupted disinfection is guaranteed at all times – not least thanks to empty container detection and automatic switchover.
Custom solutions with maximum safety
The DULCO®Vaq system components are available in various performance classes from 0 to 200 kg/h. The main components are supplemented by matching ProMinent safety equipment. ProMinent specialists design the system individually to specific requirements, taking into account the applicable technical rules for hazardous substances as well as local regulations. The solution from ProMinent complies with all important safety standards. Optimally matched components guarantee operational reliability of the system.
Injectors for chlorine gas generate a stable vacuum even at high operating pressures.
Motorised control valve for chlorine gas type PM 3531 ensures precise electronically controlled metering of the chlorine gas flow. The linear control characteristic is guaranteed by an externally controlled step motor.
Vacuum dosing regulator meters chlorine gas cost-effectively and highly efficient. Maximum possible operating safety and reliability is ensured by the use of high-quality materials, such as tantalum and silver.
Vacuum switches PM 400 and 440 automatically and reliably switch between two chlorine gas storage tanks. They therefore ensure an uninterrupted chlorine gas supply, even if a chlorine gas storage tank becomes empty.
