When water is heated, the process can cause scale to be deposited in plumbing systems and on heating/heated surfaces. Scaltrol Inc. has been offering solutions for the scaling and staining issue for over 10 years. Equally at home in commercial kitchens where dishwashers, booster heaters, ice machines, combi-ovens are used TO pressure washers, autoclaves, sterilizers TO reclamation sites TO home hot water heaters. The patented dispensing units sold by scaltrol inc include a dispense head that meters a relatively small amount of a food grade, NSF Standard 60 certified proprietary complex blend of material into the water flow of conventional plumbing systems. The material, typically enclosed in a replaceable cartridge is designed to successfully treat total hardness or hard water and other objectionable conditions such as corrosion. The method of manufacturing the treatment cartridge is also patented. The system will release the sequestrant under operational pressures and water flows, the process is sometimes referred to as sequestration. Calcium carbonate (lime scale), calcium sulfate, iron and manganese are often found in public and private water supplies. Scale inhibition, scale inhibitor, scale removal are added benefits. The most popular units include the SC50, HSC50, SC100, HSC100 and the SC500. Replacement cartridges include the RSC50, RSC100 and the RSC500. Samples of scaled elements dramatically depict the need for scale control.
