The ROELITE9 targets a buyer who has decided the single alkaline cartridge on the cheaper models is not enough and wants the mineralisation done properly. Five separate stages is a real architectural difference rather than a badge, and at nearly twice the weight of the standard chassis the build is visibly heavier. The compromise is the tank: 2.2 gallons against 3.2 usable on the standard system, so it draws down noticeably faster during a dinner-service burst even though rated production is higher. Express Water publishes no pH range, no mineral output figures and holds no certification for this model, which for a product sold on mineral content is the central weakness. At three hundred dollars it costs more than the tankless Model 6 that produces six times as much water.
- Five distinct mineralisation stages rather than the single cartridge used elsewhere in the range
- 0.0001 micron membrane rated at 100 GPD
- Heavier build at 24.7 lbs, roughly double the standard chassis
- Standard cartridge sizes despite the premium positioning
- Leak-detection and quick-connect fittings carried over
- Smaller 2.2 gallon tank than the cheaper systems, so it empties faster in use
- No published pH range or mineral output despite being sold on mineral content
- No NSF listing
- Costs more than the 600 GPD tankless Model 6
- One-year warranty
- Nine cartridges to track and replace
The ROELITE9 is Express Water's premium tank system, built around a 0.0001 micron membrane with five separate mineralisation stages after it rather than the single cartridge used on the ROALK10. Production is 100 GPD into a smaller 2.2 gallon tank, and the assembly weighs 24.7 lbs against 12.8 lbs for the standard chassis. Dimensions are 18.5 x 14 x 5 in.
