12500 GPD RO, 5 4x40 Mmbrn Cntrl AF PPG
Delivering 12,500 GPD of spot-free, low-TDS water with automated reliability for your high-demand operations.
The challenge
High-demand commercial facilities face costly downtime and equipment damage from hard water scaling and contaminants that reduce efficiency and increase maintenance expenses.
Without reliable low-TDS water, food and beverage quality suffers, dishwashers and ice machines foul, and industrial processes risk non-compliance and product defects.
How it works — the technology
The Nelsen 12500 GPD Reverse Osmosis system uses five robust 4x40 membranes to remove dissolved solids and impurities at a commercial scale, producing consistently purified water.
Its advanced NRO ROC2 controller automates the process, ensuring continuous operation with automatic membrane flushing to minimize fouling and extend membrane life, while pre- and post-filter gauges provide real-time maintenance insight to prevent performance loss.
Capacity & what it handles
- up to 12,500 gallons per day of low-TDS purified water
- dissolved solids and contaminants that cause scale and equipment damage
- impurities that reduce food and beverage quality
- water contaminants risking compliance in medical and industrial applications
- scale buildup that shortens equipment lifespan
