The Crystal Quest Demineralizing (DI) Water Filtration System is a commercial and industrial water treatment system built for demineralizing applications that require a properly sized filtration setup. This configurable product family is available in multiple lower-flow, mid-flow, and high-flow commercial configurations, with model selection based on service flow, pipe size, media volume, tank size, control-head type, backwash demand, source-water chemistry, and available installation space. It uses demineralizing multi-media, heavy-duty composite fiberglass tanks, high-flow distributor components, timer control valves, and all-brass motor-driven control valves with adjustable backwash cycles on applicable configurations. Control head options may include automatic, manual upflow, and manual downflow with backwash on supported models, with availability varying by selected GPM and configuration. Because flow rate, control head type, pipe size, media volume, tank size, backwash demand, drain capacity, and installation space vary by model, this system should be selected with commercial water sizing guidance before ordering.
This Crystal Quest DI water filtration system is designed for commercial and industrial buyers who need a scalable demineralizing filtration platform. Available GPM options help match the system to facility demand, plumbing size, media volume, and available installation space.
The system can be configured with automatic, manual upflow, or manual downflow with backwash control head options on supported lower and mid-range models. Compatible electronic control valve families include 5600, 2510, 2850, 2900, 3150 / 3900, and 3900 depending on the selected GPM and model.
Crystal Quest lists heavy-duty composite fiberglass tanks and high-flow distributor components for this system. These features support commercial filtration installations where tank sizing, service flow, and backwash requirements must be matched to the site.
Optional add-ons may include meter valves and NXT Display Controller options where available. Any backwash bypass, upgraded controller, multi-tank, or skid-mounted configuration should be confirmed before purchase because availability may vary by model and quote.
This commercial DI water filtration system is built for facilities that need a configurable demineralizing setup. Select the model by service flow, peak flow, pipe size, media volume, tank size, and control head type.
Because the lower-flow 11 and 13 GPM models differ from larger backwash-capable configurations, final selection should account for how the control head, backwash flow, and site plumbing match the intended use.
