15000 GPD Comm RO

When a facility needs flagship-level purified water volume with a clean, switch-based control scheme, the Nelsen 15000 GPD Commercial Reverse Osmosis system answers the call. Delivering roughly 15,000 gallons per day from six 4x40 membranes and powered by a 220 volt pump and solenoid, this floor-stand unit pairs maximum capacity with straightforward, maintainable operation.

Top-Tier Output, Uncomplicated Operation

Six 4 inch by 40 inch membranes on the 440 series platform give this system its high-volume capability, rejecting dissolved solids and contaminants as pressurized feed water crosses each membrane surface. A 220 volt pump supplies production pressure while a 220 volt solenoid handles control valve actuation, keeping the design simple and relying on conventional pressure and level controls rather than an integrated electronic controller. It is a practical, economical route to very high output.

• Approximately 15,000 gallons per day of purified water
• Six 4 inch by 40 inch membranes on the 440 series platform
• 220 volt pump and solenoid for production and control
• Floor-stand frame, about 224 pounds as a complete unit
• Switch-based operation without an electronic controller
• Engineered for the highest-volume commercial demand

This capacity supports large food and beverage production, high-throughput car washes, extensive greenhouse and agricultural operations, and industrial process or makeup water applications. Supplying purified, low-TDS water at this scale reduces scale buildup, spotting, and contaminant load across an entire facility, protecting downstream equipment and supporting consistent product quality through periods of peak demand.

Protecting a six-membrane bank requires comprehensive pretreatment. Feed water should be dechlorinated and clarified of sediment, and maintained within recommended hardness, temperature, and pressure ranges to prevent premature fouling or membrane damage during continuous service. A water analysis before installation guides pretreatment design and helps set realistic production expectations. With disciplined prefilter maintenance and periodic membrane monitoring, the Nelsen 15000 GPD floor-stand RO delivers dependable, very high-volume purified water at a strong value, giving the most demanding operations a robust and economical option when they need flagship capacity without the cost or complexity of an onboard electronic control package on their system. Because operation rests on conventional pressure and level controls, staff should understand how those switches drive production and shutdown, and keeping spare prefilters and seals on hand allows routine service to be completed quickly so the facility is never left short of purified water during a high-demand stretch of operation throughout the year.
