Marine Growth Control

MGPS / ICAF Systems

Impressed current anti-fouling for seawater systems, inhibiting marine growth settlement in sea chests, strainers, coolers and cooling circuits.

PrincipleControlled DC to copper plus aluminium or iron anodes
DosingTypically below 2 µg/l for each metal
MountingSea chest, strainer or sea tube
The Challenge

Marine Growth Closes Down Seawater Circuits Quietly

Settlement in sea chests, strainers, coolers and condensers restricts flow, lifts cooling temperatures and turns into unplanned cleaning work at the worst moment.

Our Response

Prevent Settlement Instead Of Cleaning It Out

Controlled direct current to copper anodes, with aluminium or iron anodes assisting distribution, inhibits settlement continuously through the circuit at very low dosing levels.

The System In Motion

Dosed Ions Carried Through The Seawater Circuit

  • Seawater flow
  • Copper and aluminium ions
How Protection Is Delivered

Three Steps, Continuously

  1. 01

    The regulated panel supplies a set current to each anode channel.

  2. 02

    Copper ions released into the intake flow inhibit larval settlement.

  3. 03

    Aluminium or iron ions assist distribution and support a protective downstream layer.
