Fontus water provides demineralization plants for water. Deteriorating quality of water is another concern due to the increasing pollution of water supply sources [surface and underground]. Centralized air-conditioning requires cooling towers to consume large amounts of fresh water to replace evaporated water. Due to poor input water quality, there is a need to install adequate water treatment system for them to operate at full capacity. Unreliable power supply has led shopping malls to install mini power plants that produce power from steam. These power plants need treated water to run in peak running condition. Demineralization plants remove dissolved impurities eliminating down time of these boilers and mini power plants. Featues: simple, compact and easy to operate; effective and versatile to treat water from any source; minimum maintenace; designed to meet desired water quality; and available in all capacities.
