A dirty corroded Salt Cell VS a clean Salt Cell

This is one of the common problems that we come across. This probably accounts for 60% of all the problems we encounter with salt chlorinators. In the picture the cell on the LHS is "dead" Note the white calcification deposits on the plates and on the water sensor at the cap. Regular inspection and cleaning is required, even though these are self cleaning units. This is a common problem amongst all the salt chlorinator brands in the field. There is no exception.

Testing a Salt Chlorinator in the winter with heated water

Workshop testing of a salt chlorinator, simulating summer conditions

The majority of salt chlorinators presently in the field in New Zealand do not perform exactly as they should in pool water that is usually colder than 16degC. In July we have some pool water temperatures in the Auckland region that can drop as low as 9 - 11degC. From a design and technical reason salt water chlorinators do not work as they should in these cold water conditions and owners often suspect that their unit may be faulty, they disconnect and end up bringing them into our workshop for testing. To overcome this problem we keep our salt water tank at the most common salt level and we maintain around 20degC prior to wet testing any chlorinator cell. This way we can eliminate the winter cold water pool problem scenario ...... read more

The Relationship between your Salt Chlorinator and pool water temperature

A salt chlorinator works by separating Chlorine Ions from salt granules which are added to the pool water and then dissolved naturally. Once the salt solution has passed through the salt cell and returned to the pool it converts back to Sodium Chloride ( salt ). This is then be re-used. Salt does not evaporate, it is lost through filter back washing/rinse or dumping water following heavy rain fall. This process is mediated by a specially designed ionisation cell ( a number of specially coated metal plates housed together inside a plastic housing plumbed into the return line plumbing to the pool ( after heaters etc ). By design the majority of salt cells currently available are designed to perform when the pool water temperature is not lower than 16degC ( Winter ). If this recommended water temperature is not reached most salt cells will shut down and not produce any chlorine ( sanitiser ). The owner then suspects that the unit is faulty and seeks help and assistance from others. Prior to us wet testing the chlorinator we ensure that our test tank salt water solution is heated to around 20degC. A unit that does not produce chlorine on site in cold water will often work fine in our workshop. If this is not the case we have to investigate further, at least one obstacle is out of the way...... its not water temperature!
