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-Ons

UV 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
