PES Spotless Water Systems
Deionized Water Systems for Spot-Free Results
Start a PES DI tank program for dependable spot-free rinsing in auto detailing, window cleaning, solar-panel care, and other professional applications.
Designed for the final rinse
When the finish matters, the water matters
Ordinary water can leave dissolved minerals behind as it dries. Deionized water removes charged mineral ions and helps reduce spotting and streaking on finished surfaces.
Auto detailing
Produce a cleaner final rinse on vehicles while reducing mineral spots.
Glass & windows
Help preserve clarity on glass where leftover mineral residue is easy to see.
Solar panels
Use low-mineral rinse water on surfaces where spotting can affect the finish.

Handling & transportation
Use it upright. Transport it securely.
The tank must remain upright during operation, but it may be moved upright or laying down when properly secured.
Operate upright only
Stand the tank upright before attaching the inlet and outlet. Never operate it while laying on its side.
Move upright or laying down
Both positions are acceptable for transport. Secure the tank against rolling, tipping, and impact, then stand it upright before use.
Secure all connections
Confirm that both fittings are properly attached before operation to help prevent leaks and maintain consistent flow.
Know when to swap
Rising TDS or the return of small water spots usually indicates that the tank is becoming exhausted.
