Sacrifical Anode for Salt Chlorinator
Lead Time: Next Working Day
Sacrifical Anode for Salt Chlorinator 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)
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.
The Anode is normally place between filter and heater or pump and filter
