7500 GPD Comm RO (3) 4x40 Mmbrn w/ Cntl
7500 GPD Commercial RO: Intelligent high-output water purification for flawless operations
The challenge
Hard water and dissolved contaminants cause costly scale buildup in commercial equipment, reducing efficiency and increasing maintenance expenses. Facilities like food production, laboratories, and car washes face operational disruptions, non-compliance risks, and elevated utility costs when water quality is inconsistent.
Without reliable low-TDS water, businesses experience reduced equipment lifespan, energy waste, and poor product quality—leading to downtime and lost revenue.
How it works — the technology
The Nelsen 7500 GPD Commercial Reverse Osmosis system uses three robust 4x40 inch membranes on the 440 series platform to reject dissolved solids and contaminants at a commercial scale. The integrated NRO ROC2 controller intelligently manages the entire RO process—overseeing water production, membrane flushing, and shutdown protocols—to maintain consistent permeate quality and protect membrane life.
Operating on stable 220 volt power, this floor-standing unit delivers approximately 7,500 gallons of purified water daily with automated control that adapts to fluctuating feedwater conditions, ensuring uninterrupted, high-quality output.
