Salt Water Chlorinators – The Watermaid Electrolytic Cell
The Ezy Clean Salt Cell
The Watermaid Ezy Clean Salt Cell is installed on the return to pool line, after the filter. All water that flows through the system is first of all filtered, and then chlorinated via the Watermaid salt water chlorinator cell, killing all harmful germs, viruses and bacteria.
Easy to Clean Salt Water Chlorinator Cell
All salt chlorination systems require periodic cleaning of the cells to remove calcium deposits. This is particularly noticeable on a new installation where concrete dust and debris are left in the pool or if calcium is added to the pool as part of the routine chemical adition. In all other models, if the deposits cannot be rinsed off with a garden hose, a solution of muriatic acid must be used to clean the cell. The entire cell is removed from the pipe work, capped and acid washed which reduces its life.
The Watermaid Ezy Clean Cell has the advantage of being able to be disassembled to allow for easy cleaning. The solid titanium cathode pulls out from the top of the cell and can be quickly cleaned and freed of the calcium deposits by wiping it down with a rag. The deposits only form on the cathode so there is no need to acid wash the Watermaid cell. In a matter of minutes the cell can be cleaned and be ready to start chlorinating your swimming pool again!
Salt Water Chlorinator Cell Installation
The Cell can be installed by simply replacing just about any 90° elbow in the return to pool line and replacing it with a T-Piece upon which the Watermaid Ezy Clean cell sits, guaranteeing that a gas trap is formed which is compulsory on all units installed in Australia. This type of installation makes the Watermaid salt cell the tightest installation length on the market.
The Cell can be fitted to either 40mm or 50mm (11/2 inch or 2 inch) PVC Pipe systems.
Long Life Water Treatment Cells
Watermaid water treatment cells are designed for durability. The cylindrical design electrodes are used instead of plates to improve chlorine generation and reduce the chance of fouling. One size will chlorinate up to 150 000 litres of water.
A low voltage DC current is applied to the Watermaid Cell from the power supply. As mild saline pool water is passed over the electrodes inside the salt chlorinator cell, the salt molecules are split into sodium and pure chlorine. At the same time water molecules are split into hydrogen and oxygen these split compounds then form sodium hypochlorite. Sodium hypochlorite (NaHCL – Liquid Chlorine) is the equivalent of liquid pool chlorine. This sanitizer is produced and dispersed into the flowing filtered water, back to the pool or spa.
The big advantage to this process is the removal of chloramines from the water. The high levels of chlorine produced in the cell constantly “ super chlorinate “ the water removing the waste that is chemically bonded to the chlorine. These combined chlorine compounds (chloramines) give swimming pools the typical bleach smell and contrary to popular belief, the strong smell of chlorine does not mean that the pool has enough chlorine. It simply means that the pool water is contaminated with waste. Additional chlorine will break down these waste molecules and free up the chlorine. This is why a properly sized salt water pool is capable of generating enough chlorine to burn off the wastes and eliminate the typical “bleach” smell associated with swimming pools. These wastes also irritate the eyes and lungs of swimmers.
