Pure water is simply the H2O molecule. Anything else like minerals, metals, salt, cations, or anions in the water are considered Dissolved Solids. These are what leave water spots on glass and surfaces after the water dries.
TDS measures the amount of these "Total Dissolved Solids" within your water to determine if it is Hard (over 100) or Soft (under 100). You need to consider both your TDS and frequency of work to find your perfect pure water system.
You can measure your TDS at each job site to ensure you are producing pure water for spotless windows with a helpful TDS tester. TDS meters come in a few varieties including in-line meters that attach to your purification system and pole, or in a portable version that looks like a TDS Pen.
Your TDS determines what type of purification system you need and how high your operational costs will be.
If you're lucky enough to work in a Soft Water area, you can use any of the XERO DI Systems. Start small with the trusty DI Tank which is one single chamber to hold DI Resin or go to the top of the line with the DI Cart Double which is built to last on a sturdy frame. You can check out all the DI systems to find the one that best fits you.
For hard water areas, running only a DI only unit is not going to be cost effective because you will run through the DI Resin incredibly quickly. Instead, you need a multi stage system that will draw out a majority of the impurities before the water hits the final DI chamber for that final polish.
Here's an example:
If your water is 222 ppm you could expect about 700 gallons for 23 working hours per resin refill which is around $139. A Multi Stage system like the XERO Pure will give you 5,500 gallons for 184 hours and it would only be $79 to refill the resin. To accomplish that same 5,500 gallons with only a DI Tank, it would cost you close to $1,100. You can easily see how that would add up.
Multi Stage systems utilize at least a pre-filter, RO Membrane, and a DI Housing to effectively purify hard water.
XERO offers the Pure Line with options for any budget or workload.
The original XERO Pure is our most popular system because it's affordable and cost effective. This system utilizes a carbon filter to remove large impurities from the water. Then an RO Membrane to remove the bulk of the contaminates before the water finally moves to the DI resin for that last finishing touch to get below 10 ppm. All of this is built onto a durable and portable frame that makes getting around your job easy.
If you work with a multi person crew, heights over 60 feet, or need a compact system, we'd be happy to guide you through your search. Reach us on chat or by phone at 862-220-3875 and our knowledgeable staff will answer all your questions to find your perfect pure water system.
If you are looking for a straightforward system that is built to last, the XERO Pure is the choice for you. Work at 2 - 3 stories easily without a pump. Perfect for hard water areas. proprietary filters keep this an economical option. Click below to learn about all the great features!
If you are working with two person crews or at heights that would normally demand a pump, then consider the MAX. The Dual ROs on this unit produce 1 GPM so you can hit 4 - 5 stories easily. It's the Goldilocks of the XERO Pure lineup offering more power than the Pure but less weight than the Triple.
If you need the ultimate in pure water production, check out the XERO Triple Pure. This system utilizes three RO Membranes to increase efficiency and decrease waste. With the greatest GPM output in the XERO Pure line, this is sure to handle even your biggest jobs.
XERO DI Tanks are great for soft water areas. Once your TDS meter starts reading too high, just replace the DI Resin. It's easy to change out the old resin too. If you work out of a smaller vehicle and only need occasional pure water, this is it!
This game changing DI Cart is designed for soft water areas. It features a sturdy frame, non-proprietary filter changes and two 40 Inch DI Housings. Upon delivery, this DI Cart is fully assembled and filled with resin, ready to go.
