Flow-Rite Deionizer System

Pure Water | Extended Battery Life | Easy Maintenance

The Flow-Rite Deionizer System is a high-performance water purification solution designed to maximize the life and performance of your industrial batteries. By removing harmful ions and heavy metals from tap water, this system ensures that only ultra-pure water enters your battery cells—protecting your investment and reducing maintenance costs.

Whether you're managing a single forklift or an entire fleet, the Flow-Rite Deionizer is a smart, cost-effective way to produce battery-grade water on-site, eliminating the need for expensive distilled water or complex filtration systems.


💧 Why Use a Flow-Rite Deionizer?

Tap water often contains dissolved solids, minerals, and heavy metals that can damage batteries over time. These impurities can:

  • Shorten battery life
  • Increase self-discharge
  • Cause uneven cell voltages
  • Lead to costly replacements

The Flow-Rite Deionizer System uses ion exchange technology to remove these contaminants, delivering water with purity levels below 50 parts per million (ppm) total dissolved solids (TDS)—ideal for battery watering applications.


✅ Key Features & Benefits

🧪 Advanced Ion Exchange Filtration

  • Removes ions, minerals, and heavy metals from tap water
  • Produces water comparable in purity to distilled water
  • Helps maintain optimal battery performance and longevity

🔄 Easy Cartridge Replacement

  • Uses a separate bed ion exchange cartridge
  • Cartridge is disposable and easy to replace—no tools required
  • Built-in water quality light turns red when TDS exceeds 50 ppm, signaling it’s time to replace the cartridge

💡 Water Quality Indicator

  • Dual-color LED light monitors water purity in real time
    • Green = Water is pure
    • Red = Replace cartridge
  • Ensures consistent water quality without manual testing

💪 High Capacity

  • Each cartridge can purify up to 600 gallons of water on average
  • Output varies based on incoming water quality (from 250 to 1,500 gallons)

🧰 Simple Installation

  • Standard hose fittings and quick-connect couplings
  • No plumbing or electrical work required
  • Compatible with Flow-Rite’s Millennium Evo and Pro-Fill battery watering systems

📊 Cartridge Output by Water Quality

Tap Water Quality TDS (PPM) Output (Gallons)
Excellent 50 1,440
Good 100 720
Average 150 480
Poor 250 288
Very Poor 300+ 240

Note: For inlet water above 300 ppm, a prefilter is recommended.
