ANODES  
A MUST FOR ANY SALT WATER POOL 
 
As the trend for salt water pools using salt chlorination  
increases, so does the realisation that there is a downside. 
 
Salt Chlorinators can cause a number of problems including plaster discolouration, damage to heaters and black staining to metal ladders, lights etc. This is caused through “Galvanic Corrosion”. 
 
The problem of galvanic corrosion can be easily stopped by using a sacrificial Zinc Anode, this simply allows the anode to erode before all other metals in the water. 
 
Thermalec can provide you with the solution. Zinc anodes designed for the pool industry, to fit into new or existing pools. 
HOW IT WORKS 
The in-line zinc anode is attached to the bonding wire, thereby protecting all metal part (heaters, lights, rails, etc.) from galvanic corrosion. Zinc anodes will sacrifice themselves and corrode before all other metals in the pool. Zinc anodes need to be replaced approximately every 2-3 years. 
 

REASONS FOR USING ZINC ANODES IN CHLORINE-GENERATED SALT WATER POOLS 

Any time you have different metals (copper, stainless steel, etc.) in a salt water pool, you are creating a battery, because of this an amount of current flows between the metals. The electrons that make up the current within the pool are supplied by one of the metals, giving up bits of itself in the form of metal ions to the pool water. This is called galvanic corrosion. Galvanic corrosion causes plaster discoloration and metal erosion. The best way to inhibit the effect of galvanic corrosion is to use a zinc anode. Zinc is a metal that gives up its metal ions faster than other metals in the pool. In other words, the zinc anode will erode instead of other metals (pool light, rails, heater, light niche, ladder, etc.). The zinc ions will not discolour the pool plaster. The zinc anode should be replaced after half of it has eroded. This takes approximately 2/3 years. 
 

 
A MUST FOR ANY SALT WATER POOL 
Thermalec have a range of Anodes specifically for the pool industry. They are designed for new installations and existing installation and can be fitted easily. 

T104-C Anode
T104-C 
 
 
Retrofit Anode for existing pools 
The T104-C inline zinc anode is 
designed with a copper bonding 
wire attached thereby protecting 
all metal parts against the effects of galvanic corrosion. The T104-C is available to fit 1/½” and 2” size pipes. The see through housing allows you to easily see when the anode has 
depleted and needs to be replaced. 
No re-plumbing required. A must for salt water pools. 
Replacement Anode Kit 
(No. T104-R) 
T104-D Anode
New Pool Installation 
T104-D 
 
Designed for new installations 
but can be easily fitted to existing installation, standard pipe fitting 2” can be reduced to fit 50mm or 1½” pipe.The T104-D helps protect heaters, pool lights and rails from damage due to galvanic corrosion. Inline zinc anode for new installations - 4 feet of #8 copper bonding wire included. Replacement Anode Kit (No. T104-R) 
T104-D Spigot Anode
Any Tee Anode  
T104-D Spigot 
 
The T104-D Spigot is designed to fit into any 2” Tee connector. The inline zinc anode is attached to the copper bonding wire thereby protecting all metal parts against the effects of galvanic corrosion. The see through 
housing allows the anode to be 
easily replaced when depleted. 
T104-B Ladder Anode
T104-B 
 
Ladder Anodes now available. 
Simply attach the Anode to your pool rail or ladder under the water line 
Available to suit 1.9", 1.5" or 1.25" rail. 
Please state size required when ordering.
