Navien GXXX001725 Anti-Scale System

This Navien water treatment device is designed to prevent the buildup of mineral deposits, commonly referred to as scale, within plumbing systems. The system operates by transforming calcium and magnesium ions, which are the primary constituents of scale, into a harmless crystalline form that does not adhere to surfaces. This process is achieved through Template Assisted Crystallization (TAC), a technology that does not require the use of chemicals or salt. The system is capable of treating up to 20 gallons per minute (GPM) and can operate at temperatures up to 140 degrees Fahrenheit. It features a stainless steel body for durability and includes a cartridge that can be easily replaced after approximately two years of use.
