Crystal Quest Commercial Mid-Flow Reverse Osmosis System

Commercial-Grade Water Purification for Any FacilityThe Crystal Quest Commercial Mid-Flow Reverse Osmosis System delivers industrial-strength water purification for restaurants, hotels, breweries, medical facilities, schools, and light manufacturing applications — from 500 to 7,000 gallons per day. Every system is factory-tested before shipping and engineered for continuous-duty operation with minimal downtime. Modular, expandable, and low-maintenance, these systems are built to last 15–20 years. Benefits Compact, space-saving design Easily accessible components for fast service Expandable and lightweight aluminum frame Fully equipped and customizable Low operational and maintenance costs Factory tested and preserved CE compliant Made in the USA ISO certified components Storage Tank Kit Components RO System — Commercial-grade, 500–7,000 GPD with integrated prefiltration to extend membrane life. Water Storage Tank — Atmospheric tank (165, 220, or 500 gallons) sized to your system and available space. Pump — Delivers purified water from the tank to your facility on demand. Float Switches — Automatically cycles the RO system on/off based on tank water level. Note: Storage tank kit configurations (165, 220, and 500-gallon) include large-format tanks requiring freight delivery. Freight is quoted separately and confirmed before order processing. For tank kit configurations, use our quote form for a full project estimate including freight. Optional Add-OnsUV Water Sterilizer (12 GPM)Adds microbiological protection downstream of the RO system — ideal for food service and medical applications. TDS Meter (Panel Mount)Provides simultaneous monitoring of feed and product water quality for real-time system performance verification. Available Upgrades Stainless-Steel Rotary Vane Pump — Longer lifespan; better resistance to high TDS and corrosive materials (500–2,500 GPD systems) Concentrate Recycle Valve — Increases system efficiency by recycling wastewater into the feed stream SWP Digital Dual TDS Controller — Simultaneous monitoring of feed and permeate TDS SWP Digital TDS/Conductivity Controller S150 Computer Controller with Feed Flush — Pre-treatment lockout, tank level input, LED status display, alarm function (4,000 GPD and up) Chemical Pump Outlet Blending Valve — Mixes feed water with RO permeate to achieve a desired TDS level Permeate Sample Port 240V or 110V, 50–60 Hz options Operating Specifications Parameter Value Motor (hp) 0.5–1.5 Voltage 110V / 220V Hertz 50 or 60 Feed Connection 3/8" or 1" Product Connection 3/8" or 1" Waste Connection 1/4", 3/8", or 1" Min.
