Dynamic copper dosing

Antifoulant dosing dynamically controlled based on water flow, significantly reduces the consumption of copper anodes.

Proportional copper dosing

Antifoulant dosing based water flow eliminates unnecessary consumption of copper.

Traditional set-up

MGPS/ICAF antifouling systems are traditionally designed for constant antifoulant distribution, based on maximum seawater pump capacity. During periods with less water flow, significant amounts of copper are wasted.

Reduced copper consumption

Although dynamic copper dosing have become available for many, few seem to realise the opportunities for cost optimisation. The cumulative saving over years of reduced copper consumption may be significant.

Basically, the CathFlow® control panels enable automatic control of the copper consumption based on the water flow.

The system features both digital and analogue (step-less) control of the individual output channels.

To implement dynamic copper dosing, connect a standard industry 4-20 mA current loop signal, representing the water flow, to any of the analogue I/O ports on the CathFlow® control panel. The linked outputs (selected in the menu), will step-less regulate the copper dosing in accordance with the signal.

Alternatively, a simple switch or a remotely controlled relay from the pump or a flow meter, can be attached to any of the digital ports at the CathFlow® control panel. The panel will toggle the copper dosing to a pre-set high level or to a “resting” low level.
