Everything you need to know about Cuprion®
Since the late 1970s, Cathodic Protection Co. Ltd have manufactured and supplied the innovative Cuprion® anti-fouling system.
Mussels, Clams and Zebra Clams can build up in pump intakes, impeller chambers and downstream piping – reducing pump efficiency and increasing maintenance costs. The Cuprion® range delivers long-term, effective and cost-efficient protection against hard biofouling.
The range includes copper, aluminium and chlorine-based electrolytic systems, which can be tailored to your exact requirements.
The benefits of Cuprion®
There’s an array of advantages that Cuprion® anti-fouling systems bring, including:
- Reduction in power requirements over alternative methods for fouling control.
- Low maintenance system.
- Low power requirement.
- No handling or storage of chemicals required.
- Environmentally acceptable.
CPCL’s extensive experience in the design of Cuprion® systems ensure that exceptional anti-fouling equipment can be provided for a variety of applications. Offshore sea water lift pumps, offshore fire water lift pumps, jockey pumps, jetty fire water pumps and industrial sea water cooling systems can all benefit from the Cuprion® range.
How it works
The method is based on the use of impressed current on copper and aluminium anodes, which are themselves contained within an insulated steel frame which forms the cathode.
The anode or cathode electrode unit is suspended from the pump motor base within the confines of the caisson – so that all water entering the pump must pass the electrode unit.
The Cuprion® system consists of two parts, the electrode unit and the control panel. The electrode contains a number of copper and aluminium anode bars held together in a steel frame to form the cathode. The actual number and size of the anodes is configured to suit each installation and available space for mounting the electrode unit.
The anodes are connected to the constant current rectifier located within a safe area. The control panel is designed to regulate the anode currents in both ‘pump on’ and ‘pump off’ condition, so that during the pump standby condition an atmosphere of copper ions in the local environment will keep the pump free from fouling.
Deck mounted options
For some environments, the traditional method of pump/electrode configuration may not be suitable. As an alternative, CPCL offers the deck mounted system in which the anodes are located inside of a tank – through which sea water is fed from the main sea water mounted system.
As water passes through the tank, the carefully controlled anode currents ensure that the correct dosing level is applied for the particular application. The treated water is then piped down directly to the pump suction.
In this way, several pumps can be protected against fouling from a single treatment source. The Deck Mounted Cuprion® system is ideally suited for retro-fitting, where the pump/electrode configuration may not be possible.
