About the XERO DI Tank

Water-fed window cleaning in soft water areas has been made simple with the lightweight and compact XERO DI Tank. 

XERO DI Tanks are proudly made in the USA by our team with durable brass fittings that fasten to your hoses securely. Equipped with the XERO 3/4" Pure Garden Hose to Female Swivel Adapter, a Garden Hose Male x 3/4" NPT male, and XERO virgin resin, this tank will be ready to clean as soon as it reaches your doorstep.

Once your TDS meter reads higher than usual, these tanks can be refilled with new resin, so you can keep using them for your work. They are designed to be used standing upright to work properly.

The total capacity is four gallons of purified water for the 1/2 cubic foot tank and 8 for the 1 cubic foot tank

These tanks are economical, easy to use, and built to last. They're perfect for areas with soft water or for the window cleaner just beginning their water-fed journey.

Clean up your act with the XERO DI Tank, available in multiple colors.

DI Tanks should only be used in soft water areas for best performance.

Questions & Answers

Have a Question?

Ask a Question
  • What is the max flow rate recommended for this at TDS of 300ppm to still lower TDS effectively/reliably to below 5-10ppm? I wondering if I can run this continuously with a water fed brush or if I needs to pre-run and fill a tank from which I would then pump DI water for washing a 40 panel solar array.

    We would not recommend this tank for a TDS of 300. This is designed for a TDS of about 100, anything higher, we would recommend a multi-stage system like the XERO Pure, or XERO Pure MAX, both of which will run continuously.

  • What is the best way to store your DI tank between uses so the resin remains active? I plan on using the DI tank roughly 4 times a year.

    Hi! To keep your DI tank safe in between uses, alwasy keep water in to keep your resin hydrated!

  • Would this work well for washing cars?

    Hi! Great question! While pure water is a great choice to clean a multitude of surfaces, and is safe to clean cars, you have to be careful with how you apply pure water as most waterfed brushes will scratch the finish.
