| ADVANTAGES
AND DISADVANTAGES OF THE PETIÓN®
SYSTEM COMPARED TO OTHER SYSTEMS WITH ELECTROLYTIC TANK |
 |
| PETION® SYSTEM |
HYPOCHLORITE SYSTEMS |
| Protects against biological growth and corrosion. |
The system only protects against biological growth, but increases the corrosion, as the chlorine is a very corrosive agent. |
| Low electric consumption. (3 A) |
High electric consumption. (60/150 A) |
| Cheap electrodes with high frequency of replacement. |
Expensive electrodes with low frequency of replacement. Calcium scales grow in the electrodes. |
| Small machines make expensive the system big machines make cheap the system. |
When there are many seawater inlets many electrodes are needed and more expensive. |

(WITH COPPER AND ALUMINIUM ELECTRODES) |  |
| PETION® SYSTEM |
SYSTEMS WITHOUT ELECTROLYTIC TANK(WITH COPPER AND ALUMINIUM ELECTRODES) |
| 316L Stainless steel tank which allows a correct mixture with the needed dose without wasting product. The electrodes last longer. |
Without electrolytic tank. Install the electrodes directly in special cabins or in the seawater inlet, so they last less time due to water current in the pipeline. It needs more electrodes one set in every seawater inlet. |
| The electrolytic tank with by-pass allows the checking and replacement at any time in ten minutes. |
The installation in the pipeline does not allow checking or replacement without closing the water circulation.
In ships, if they have installed the electrode in the seawater inlet, the problem is bigger, because it only can be replaced if the ship is at the dock.
In case they install it in the sludge box it is possible to check and replace closing the valves, but would not protect the water inlet where main problems are originated. |
| Patented quadruple watertight system. |
System without special watertight proof. |
| One year warranty for electrodes lasting. Although last 18 months. |
Without lasting warranty. |

| 316L Stainless steel tank. |
Painted steel tank. |
| Copper electrode of maximum purity and wider (long lasting). Patented quadruple watertight system. |
Low purity copper electrode and narrow. |
| It has copper and aluminium electrodes. The aluminium avoids corrosion which is from seawater and copper. |
It has only the copper electrode which does not protect against corrosion. |
