Lanlang® Crystphos Polyphosphate crystal is the reliable slow-soluble food grade chemical, which brings us the economical way to protect industrial & potable water systems against scale and corrosion. It can be fed into water by a dispenser, which can be installed in almost every water system. They require no electric installation and hardly any maintenance. They only have to be refilled with balls every 3-12 months. Refilling is very easy.
