What this means for you
|
|
High purity chlorine dioxide production – 99.5% purity. Chlorine dioxide solution produced contains only chlorine dioxide and dilution water.
|
No additional chloride, chlorite, chlorate, acid, sulfate, chlorine present to cause contamination to your product or process.
With 2-chemical generators, some precursor chlorite is wasted by conversion to chloride. High chloride concentration can increase the risk of corrosion to stainless steel. The CDE generator does not add any chloride to the chlorine dioxide solution so this benefit will reduce the risk of corrosion.
|
You can safely use chlorine dioxide generated from the CDE generator in your food or potable water process with no fear of contamination or addition of unwanted chemicals or by-products. Risk of corrosion to stainless steel will be minimized.
|
|
Chlorine free chlorine dioxide produced by CDE generator.
|
No production of THM’s, AOX’s, HAA’s, chloramines or chlorophenols by chlorine dioxide made in the CDE generator.
3-chemical and chlorine-chlorite generators make chlorine dioxide in an excess of chlorine. This chlorine will enter your water circuit and make chlorinated organic by-products, chloramines and chlorophenols which are responsible for taste and odour problems. The CDE generator cannot make any of these by-products
|
You can be confident that no chlorinated organic or inorganic reaction by-products will be produced by chlorine dioxide from the CDE generator.
|
|
Only one precursor chemical required : Electricide-P1 31% sodium chlorite.
|
You only need to handle one chemical. Other methods of generation require 2 or 3 chemical precursors. The CDE generator will therefore reduce the chemical storage and handling safety risk for your site. 2-chemical and 3-chemical generators require incompatible chemicals to be stored next to each other which is inherently dangerous. The CDE generator has only one chemical so this danger is removed.
|
You will have the lowest possible safety risk related to chemical storage and handling.
|
|
pH neutral chlorine dioxide solution produced by CDE generator.
|
No acidity added to your process. If you have a recirculating closed loop water circuit, you don’t want continuous addition of acid as this will cause pH to drop and require correction with caustic. This is exactly what will happen with a 2-chemical generator. These generators operate with 250% molar excess of acid. This acid will be added to your water circuit, requiring pH correction and increasing the risk of corrosion. The CDE generator produces pH neutral solution so pH correction of the water circuit is not required.
|
You don’t need to add caustic to your water circuit to pH correct it. This is just one other chemical you don’t need to worry about.
|
|
High precursor conversion to chlorine dioxide.
|
The CDE generator chlorite conversion within the patented electro-chemical cell is near 100%. When chlorine dioxide solution is produced, overall efficiency is 74-80%. Overall conversion for 2-chemical chlorine dioxide generators is normally less than 70%.
|
Your purchases of Electricide-P1 precursor will be minimized.
|
|
Production of caustic is part of the CDE generator process.
|
15% sodium hydroxide is produced as a by-product from the CDE process. This can be used for cleaning or other pH control processes on site.
|
You get 15% pure sodium hydroxide free of charge from the CDE process.
|
|
Inbuilt safety interlocks to maximize safety.
|
Flow, pressure, temperature, current monitoring of critical processes with high and low alarms will shut down the generator.
|
The CDE generator has been looked at from a risk assessment and HAZOP perspective and engineering controls put in place to minimize risk.
|
|
The CDE generator comes complete “cabinet mount”. All components are mounted, plumbed and wired in an enclosure, ready to ship, install and operate.
|
Transportation to site and installation is easy. Just connect water, power, Electricide-P1 and control signals in; chlorine dioxide solution out and you are ready to run.
|
With relatively small involvement from mechanical and electrical trades, the CDE generator can be installed and running in a short time. Your process can be disinfected and ready to use quickly.
|
|
All mounting components used are chemically resistant to chlorine dioxide. Materials include UPVC, Vinylester, PVDF, PTFE, Viton and Kynar.
|
Unlike other systems which use steel cabinets and stainless steel fasteners (which are subject to corrosion), the CDE generator uses more expensive components which are 100% chemical resistant. The frame, fasteners and pipe clamps are all Fiberstrut (vinylester) which will stay corrosion free.
|
The CDE generator will look new and operate reliably (without corrosion failure) many years after installation. The value for money will be realized as you see the low lifetime cost of ownership.
|
|
PLC controlled system with touchscreen HMI.
|
All items are controlled from a central PLC and the touchscreen provides an operator friendly way to view plant operation and status. Fault finding is simple.
|
It is easy to train operators on how the plant operates and they will feel comfortable operating the plant. All the information you need and configuration capability is available at the HMI.
|
|
Inbuilt calibration cylinder for Electricide-P1 dosing pump.
|
The Electricide-P1 Dosing pump can be properly calibrated so that dosing is accurate and consumption of Electricide-P1 minimized.
|
You can view and accurately control the chlorine dioxide concentration produced and the amount of chlorine dioxide generated.
|
|
Inbuilt control modes: Flow Pacing; PID Residual Control; Flow Paced with Residual Trim; Manual Dosing.
|
Flexibility of control for whatever your process requires. For make-up to a cooling tower or to a water tank you can use flow pacing and dose into the make-up line. For a recirculating tank, you can use PID Residual Control. For potable water disinfection, you can use Flow Paced with Residual Trim.
|
Your process control scenario can be handled within the CDE generator and the HMI will provide you with the necessary feedback signals for verification.
|
|
Three dosing pumps can be independently controlled from the CDE generator.
|
The hardware and software control for three dosing points is built into the CDE generator.
|
You can maximize the payback on your generator by using chlorine dioxide in many applications on site. Just add dosing pumps and you can get going. No need to have your own PLC control system, the CDE generator has it built in.
|
|
Remote start/stop inputs for three chlorine dioxide solution dosing pumps.
|
Start and stop each dosing pump from remote PLC or switch contact. A flow switch or level switch or flow monitor can be used to stop/start the dosing pumps.
|
You will have full control of dosing into your process. Even though the generator has inbuilt control, you are still the master of when dosing occurs.
|
|
Pause inputs for three chlorine dioxide/ORP analyzers.
|
Chlorine dioxide dosing and PID control will be stopped if the sample flow switch inputs are not made.
|
In order to have proper residual control, it is necessary to have verified sample flow at the chlorine dioxide/ORP sensor. The sample flow switch input verifies that sample flow is present and residual control can occur. If not, dosing is stopped. You can be sure that overdosing will not occur from a non-representative sample to the sensor.
|
|
Ability to select chlorine dioxide residual or ORP for three channels.
|
Flexible measurement options. Some water circuits are clean and can use amperometric chlorine dioxide sensors and others have suspended solids requiring ORP.
|
You can select the sensor and measurement type that best suits your application.
|
|
You can select the sensor and measurement type that best suits your application.
|
You can select 4-20mA = 0 – x ppm or 0 – x mV.
|
No need to adjust the range at the residual analyzer. You can do all the adjustments at the HMI.
|
|
Remote internet access.
|
Using a secure broadband connection, users can log on to the HMI and view/operate the generator.
|
The speed of making a change to the generator or fault finding is greatly increased. In most cases, it will not be necessary to send a serviceperson to site and this will save you time and money.
