900GPD Comm RO

For small businesses, light commercial kitchens, and point-of-use applications that have outgrown a residential filter, the 900 GPD Commercial Reverse Osmosis system from Nelsen delivers a meaningful step up in purified water output. Rated to produce roughly 900 gallons per day, this floor-stand unit packs serious membrane performance into a compact, freestanding frame that is straightforward to position and service in a utility room, back-of-house, or equipment area.

Compact Single-Membrane Design

At the heart of the system is a single 2.5 inch by 40 inch membrane housed in the 2540 series configuration, driven by a pump on standard 110 volt power. Reverse osmosis works by forcing pressurized feed water across a semipermeable membrane, allowing purified water to pass while rejecting dissolved solids, salts, and many other contaminants to drain. The result is consistently low-TDS product water ideal for applications where taste, scale control, and water quality directly affect the end result.

• Approximately 900 gallons per day of purified water production
• One 2.5 inch by 40 inch membrane in a 2540 series housing
• 110 volt operation for easy connection in many facilities
• Floor-stand frame for stable, freestanding installation
• Ships at roughly 84 pounds as a complete unit
• Suited to light commercial and point-of-use purification needs

Typical homes for a system this size include coffee shops and cafes, small restaurants, dental and medical offices, laboratories, and humidification or equipment feed where high-purity water extends the life of downstream gear. Because the unit is built on the 110 volt standard, it avoids the special electrical service that larger systems demand, letting many operators bring it online without major facility changes.

Like any RO system, this unit performs best when paired with appropriate pretreatment such as sediment and carbon filtration to protect the membrane from chlorine and particulate, and it benefits from feed water within recommended hardness and temperature ranges. Routine attention to prefilters and periodic membrane evaluation keep production and rejection rates strong over the long haul. For operators who need dependable purified water without the footprint or power requirements of a large industrial machine, the Nelsen 900 GPD floor-stand RO offers a balanced, practical solution that scales with a growing operation reliably every single day. Positioning the unit near a floor drain and a properly sized feed connection simplifies setup, and leaving service clearance around the frame makes prefilter changes and membrane inspection far easier for whoever maintains the system over the years.
