Thanks to the modular design of the panel-mounted measurement and control stations, effective systems, optimised to specific user requirements, can be easily realised with the aid of the application-specific identity code ordering system. In this way, the advantages of standardisation can be combined with maximum flexibility.
Application optimised DULCOTROL® measurement and control stations are designed as complete and compact online process measurement and control systems mounted on a PE panel. As plug&play modules, minimum effort is required to install the stations in a process water bypass system. Depending on the specific water treatment application, the measurement and control stations are divided into drinking water, including food and beverage, cooling water and waste water modules.
In all model series, 1 to 3 measured variables can be configured on one panel specific to the measured water. Corresponding to requirements, the measuring devices can be equipped with measurement or manifold control functions. Further devices such as compatible filters, pressure reducers, heat exchangers or pumps for measurement water can be added to complement application-specific water treatment.
The standard version of a complete measurement and control station consists of a D1C or D2C controller for one or two measured variables, one to three sensors as well as the corresponding fittings, piping and wiring and a multifunctional operator-control module. All necessary components are perfectly matched and mounted ready for connection. To simplify and assist the calibration and servicing procedures, the operator control module features corresponding fixtures for sensors, hand-held devices and calibration solutions for all measurement parameters.
Simple and reliable configuration
With the aid of a simple identity code ordering system, it is possible to configure the required measurement and control station reliably and effectively without the need for detailed technical knowledge.
The user can assemble the application specific measurement and control station with the aid of 10 application criteria. The main selection criteria include the measured variable, the type of water to be measured and whether the task is measurement or controlling. Depending on the selected criteria, all components required for measurement or control are assembled automatically. The measurement stations configured in this way are mounted ready for connection. Only very few settings are required to install these plug&play modules and take them into operation.
 Drinking water/ Food & Beverage
The DULCOTROL® measurement and control stations for drinking water/Food & Beverage are specifically geared towards applications in the drinking water as well as the food and beverage industry. Depending on the type of water to be treated, a differentiation is made between drinking water/product water treatment and flushing water, service and process water treatment.
The term "drinking water/product water treatment" refers to a final treatment process such as the disinfection of water with drinking water properties as occurs in drinking water production as well as in beverage and food applications.
The term "rinse, service and process water" refers to all rinsing processes that occur in the food and beverage industry, aimed at cleaning and disinfecting piping systems, vessels and machines and also to process or service water with higher contamination levels.
 Cooling water
The DULCOTROL® measurement control stations for cooling water are used in all branches of industry that require cooling water treatment.
In this case, a differentiation is made between closed-circuit and open-circuit cooling water treatment processes. In the closed cooling circuit, the cooling water is conditioned by a corresponding pH value setting. Corrosion inhibitors are also added and the cooling water is disinfected with non-oxidative biocides and oxidative disinfectants.
In addition to the methods already mentioned, open cooling circuits, such as cooling towers, also include automatic demineralisation of the cooling water.
 Waste water
DULCOTROL® measurement/control stations for waste water are used in all branches of industry where waste water needs to be treated. Important examples of applications covered by DULCOTROL® include:
- pH neutralisation or pH value adjustment
- Decontamination through the elimination of reducing and oxidising agents
- Control of dissolved oxygen in biological sewage treatment
- Disinfection of treated water
Further options offered by the online measurement and control stations include the monitoring of rinsing water and the demineralisation of process water. |
