DiaZone Supercells are constructed in two equal halves separated by a special membrane. Each cell has one or more pairs of electrodes (anode/cathode) and the size and configuration of these electrodes determines the power that can be applied to the cell and its ozone output. The electrode material is solid, conductive diamond.
Cells are designated R500, R1000, R2000, R5000, etc, referring to their maximum ozone outputs in mg/h respectively.
Cell construction is robust. Little maintenance is required and service is simple. Diamond electrodes have an extremely long working life and the cell bodies, incorporating the electrodes, are moulded in an oxidant resistant plastic. There are no moving parts in the cell and water simply flows through each side at equal pressure.
When a small current is applied, ozone is generated in the water stream flowing through the cell. Typically, the current applied to an R500 cell is 2 amps at 24V DC. The cell and its operating system are therefore electrically efficient and intrinsically safe.
Ozone is generated from water at the anodes in the Supercell and a small amount of hydrogen gas is produced at the cathodes. As ozone is >12 times more soluble than oxygen, it rapidly dissolves in the water stream to form ozone-water (OW), a powerful oxidant and disinfectant.
To maintain cell performance and to avoid passivation of the cell caused by the deposition of calcium and other substances on cathodes, the current to the cell is switched at regular intervals in a process described as polarity reversal, a feature of our operating system protected by patent (pending).
