Compact, ready to connect and unpowered – that’s the way the FINESTFOG soft water technology works. Tap water flows through a column filled with cation exchange resin. Magnesium (Mg²+) and calcium (Ca²+) are exchanged for an equivalent amount of sodium ions (Na+). The water softened in this fashion will now contain a proportionately greater amount of sodium salt (cooking salt), but hardly any magnesium and calcium. Both are known as hardeners. The exhausted exchange resin is automatically regenerated by regenerating salt from the storage container. In air humidification systems the sodium ions prevent nozzles from becoming calcified and blocked. In reverse osmosis systems softening units are used for pretreating the process water.
FINESTFOG water softening systems are always of the pendulum type with two resin columns. This guarantees the availability of softwater at all times. Regeneration is quantity-controlled: only when a column is actually exhausted, will it be regenerated. This saves on salt and waste water. An electronic low-salt indicator (optional) shows when the regenerating salt is used up.
