The NWC4-80 is a reverse osmosis fresh water maker designed for a nominal capacity of 80 m3/day at a seawater temperature of 25°C and salinity of 35,000 ppm. It is rack-mounted on a stainless steel skid with an integrated PLC control and starting cabinet. The system includes an automatic freshwater flushing system for membrane protection and an automatic 'water drop' system with an alarm for high salinity. It features a digital flow-meter for accurate production readings and comes complete with raw water and carbon flush water filters.
