Electrolysis: Whenever different metals are placed in a conductive liquid you create a battery. If you connect pieces of metal, a current will flow. The current will be removing metal from one of the metal piecesā€¦ electrolysis. If the piece of metal is zinc in your flashlight battery it is good but if one is your air conditioning unit it is bad.

Galvanic Scale:

  • Zinc
  • Aluminum
  • Galvanized Steel
  • Cadmium
  • Mild Steel, Wrought Iron
  • Cast Iron
  • Lead- Tin Solder
  • Lead
  • Brass, Bronze
  • Copper
  • Stainless Steel that has been chemically cleaned
  • Metals at the beginning will corrode faster than metals at the end of the scale.

Avoid contact between metals that are farther apart on the scale. All refrigerant lines are made of copper, when you have an aluminum coil you have dissimilar metals contacting each other.

For years all air conditioning manufacturers have been plagued with the expensive problem of condensing coils corroding. When this happens it results in unsightly and ineffective coils and results in higher electric bills. Generally, condensing coils are cleaned twice a year. Corrosion is a continuous process and will degrade them between cleanings. Cleaning the coils more often shortens the life of the fins and results in the need for replacement. Coil Coatings have been used but often require re-coating during the life of the equipment. The condensing unit is made of Copper, Steel, and Aluminum. The salt air acts as an Electrolyte. Therefore the Electrolysis (Galvanic Corrosion) begins damaging your air conditioning system as soon as you turn it on. The Electrolysis will only damage one metal and that is the softest or weakest metal in the system.

The Corrosion Grenade is 100% Zinc and protects all metals on your air conditioning system because it is the softest or weakest metal on the Galvanic Scale and protects the metals acting as a sacrificial anode. As soon as you have attached the Corrosion Grenade you have introduced a softer metal than any other on the Galvanic Scale. This increases the life of your system and helps maintain its efficiency. Water heaters have used sacrificial anodes for years as well as boat engines used in saltwater.
