Galvanic isolators are often referred to as Electrolysis Blockers.
A Galvanic Isolator, or Electrolysis Blocker, protects your boat from corrosion.
If you own a boat, you most likely have heard of the problems related to corrosion.
What is corrosion?
Corrosion happens when a metal transforms due to an electrochemical reaction caused by the environment. Electrons leave the metals in the form of irons and when they do so, they leave the metal in a degraded and porous form.
When your boat is plugged into the Marina power, it’s connected to the earth. That means your boat is connected to everyone else’s potential electrical issues. Boats, Yacht Club… Any electrical issues within the power circuits could affect your boat. Which is scary!
For example, if one of your neighbour’s vessels is also connected to earth by its shore power and has a stray current issue, then your vessel has just become his vessel’s anode.
So just think about all the other potential sources attached to the earth system that could impact your vessel.
· The jetty and its power system (including the neighbour’s dodgy shore power lead)
· The club rooms with all their lighting, air conditioning and power outlets
· The Yacht club’s kitchen, just a problem waiting to happen.
A galvanic isolator disconnects your vessels’ earth wire, and protects your boat from potential corrosion issues.
Isolation is the best form of defence against corrosion.
Advancement in blocker technology
As seen in the photos, galvanic isolator’s technology has come a long way.
15 years of progress results in a smaller yet stronger electrolysis blocker.
The original galvanic isolator that was installed in most Rivera vessels was a 30AMP unit.
The new MPS electrolysis blocker is 67AMP at a third of the size.
Take care of your beloved boat and install an electrolysis blocker to feel more serene whenever you share power with Earth.
