Salt tablets for water softening purposes have been developed particularly for application in small- and medium-sized water softening installations, e.g. in private homes, hotels and restaurants, medical practices, industries, etc.
 
Made of high-purity vacuum salt, esco salt tablets dissolve completely and are absolutely residue-free. They help to regenerate the ion exchange material and to prevent it from furring up (calcification), keeping up the unit's operation while keeping its energy consumption low.
