K SERIES

Reverse Osmosis Systems
60,000 to 180,000 gallons per day

The K Series Reverse Osmosis systems are ruggedly designed and manufactured for dependable and simple operation. These units provide a higher output of continuous quality demineralized water for many industrial applications such boiler feed, bottled water plants, coolant or chemical mixing, and the list goes on. RO units are completely assembled and shipped ready for a trouble-free installation and start up. All units are factory tested prior to delivery to ensure quality and performance. All pumps are 316 stainless steel for durability and have diffuser-type design for a smooth pulse free and quiet operation. The VFD pump controller is equipped with soft start to minimize membrane hydraulic shock and potential element movement. The electronic control panel is protected by a NEMA 4 enclosure and operates on 120 vac. Many standard features are included to provide the highest efficiency from a Dayton Water Systems RO unit.
