Note - This Corrosion and Cathodic Protection section was copied directly from our old web in order to get the pages uploaded, since people have been looking for them. We have not updated them yet, so some links to other pages may not work. This section still needs some major updating, but we need to take care of other sections first, so it will be a while.

Cathodic Protection Systems & Controls Index


Northern Arizona Wind and sun has been designing low cost, high efficiency solar powered cathodic protection systems since 1984. Our CP controls have been designed specifically for use with photovoltaic CP systems, and in most cases will be 20% to 50% cheaper than conventional systems. Our systems and controls are designed for maximum efficiency with a large safety factor - your system will be more reliable, require less maintenance, and take up less space - and cost less.

We have a variety of information here on cathodic protection. Just follow the links below for more information. You can also send us E-Mail or fax us to request more detailed information or a quote.

(if requesting a quote on CP systems, we need the following information: Ground bed (anode to structure) resistance in ohms, geographical location, and required current in Amps.

Why are our CP Controls better?
Why our AERL and Solar Converter line of CP controls and Power Point Trackers can save you a lot of money in designing or upgrading solar powered CP systems.
 
AERL CP Controls
AERL standard CP controls for pipelines and larger structures, 12 amps or more, and high voltage.
 
AERL Micro-CP Controls
AERL "Micro-CP" controls, very small controls designed for well casings, bridges, and other applications requiring 8 amps or less DC current. This is the smallest and most efficient CP control available for smaller applications.
