Choosing the Right RODI System

While the initial cost of a DI tank is quite a bit less than an RODI system, because DI resin is expensive, an RODI tank may quickly pay off in the long run.

An RODI system is considered a 3-phase system because the water first runs through a pre-filter (usually carbon) to remove chlorine, then an RO filter, which removes about 98% of the water's impurities, and finally through a DI filter. The amount of costly DI resin needed is then greatly reduced with an RODI system.

However, not all RODI systems are the same.

When choosing an RO//DI system, there are some things you need to consider, including:

  • What is the average TDS of the water in my area?
  • How high am I going to be cleaning with a water fed pole?
  • How often am I going to be cleaning with a water fed pole?
  • How many people will be cleaning with water fed poles at a time?

Yes, budget is another consideration, but it's a little more complicated than just the initial purchase price. The smaller the system, the more often you'll have to change cartridges, which cuts down on productivity.

The ProTool Flat Pack Cart

For those who don't have wall space in their truck or van, we recommend the ProTool Flat Pack Cart.

The quality system features a 40" RO filter, a 20" carbon filter, and a 20" refillable DI filter, steel frame, wide base for better stability, and more. Bigger filters mean they last longer, saving you time and money.

Because assembly is required, you get a much better cart for less than lower-quality systems. We provide everything you need for assembly and detailed step-by-step instructions. 

Don't want to assemble it all yourself? 

For a small amount more, you can order an assembled cart that requires just a few steps to get up and running. Simply add the wheels  and filters, then connect two hoses and you're ready to clean. 

The ProTool RODI Cart comes with best-in-class DI and carbon filters. This means less frequent changes and more time on the job.
The 4" x 20" filters are 9 TIMES larger than the standard 2" x 10". These filters last 9 times LONGER and require 9 times FEWER changes.
