15000 GPD RO, 6 4x40 Mmbrn Cntrl

The Nelsen 15000 GPD Reverse Osmosis system with six 4x40 membranes and an NRO ROC2 controller is a top-tier, automated solution for facilities that demand very high volumes of purified water. Producing approximately 15,000 gallons per day on 220 volt power throughout, this floor-stand unit brings together maximum membrane capacity and controller-managed operation for the most water-intensive commercial and industrial settings.

Six Membranes Under Smart Control

Six 4 inch by 40 inch membranes provide the production backbone of this system, mounted on a robust floor-stand frame and powered across a uniform 220 volt platform. The NRO ROC2 controller oversees the reverse osmosis process, managing production, flushing, and shutdown so the system stays within safe operating parameters and delivers steady permeate quality. This managed control helps protect a large membrane bank from the conditions that shorten membrane life in unmanaged systems.

• Approximately 15,000 gallons per day of purified water
• Six 4 inch by 40 inch membranes for maximum output
• NRO ROC2 controller for automated, protected operation
• 220 volt power throughout the entire system
• Floor-stand frame for stable freestanding installation
• Built for the most demanding commercial water needs

Operations that draw on this capacity include large beverage and food production lines, high-volume car washes, expansive greenhouse and agricultural use, and industrial process or makeup water applications where consistent low-TDS supply is essential. The ROC2 controller adds automation and oversight that reduce manual intervention and help operators identify developing problems before they cause downtime or damage to the membrane bank.

At this scale, pretreatment is not optional. Feed water should be thoroughly dechlorinated and clarified of sediment, and held within recommended hardness, temperature, and pressure ranges so the six membranes remain protected through continuous service. A comprehensive water analysis before installation informs pretreatment and confirms achievable production for your supply. With consistent prefilter maintenance and routine membrane performance checks, the Nelsen 15000 GPD controller-equipped floor-stand RO provides the very high-volume, high-purity water that demanding facilities depend on, combining flagship throughput with the managed, protective control that safeguards a major investment over years of intensive daily operation. Installers should plan for a solid floor position, a clean 220 volt supply, and an unobstructed concentrate drain, and operators who take time to become familiar with the ROC2 controller's status indications will be better equipped to respond to feed changes promptly, keeping this high-capacity system producing dependable, high-purity water through the busiest stretches of demand.
