The DTS+Mobile is a portable, plug-and-play unit that connects to a standard dock water hose — no permanent installation is required. The Max Q+ framed watermaker does require professional installation. Kaiwi Makai Marine offers installation services throughout Hawaii.

The DTS+Mobile is designed for simple self-setup — just connect your feed water hose and plug in. For permanent system installs like the Max Q+ framed unit, we strongly recommend professional installation to ensure ABYC-compliant wiring and plumbing.

TDS stands for Total Dissolved Solids — it measures the concentration of dissolved minerals, salts, and other particles in water (in parts per million, or PPM). High TDS water leaves spots and residue when it dries on vessel surfaces. The FCI DTS+Mobile reduces TDS to as low as 5 PPM, eliminating water spots entirely.

Both models produce spot-free water and share the same core technology. The standard DTS+Mobile adds an on/off touch control switch and an auto shutoff feature for added convenience. The Lite model is $6,250; the standard model is $7,500. Both are available in 120 VAC or 208-240 VAC.

Both DTS+Mobile models are available in 120 VAC (standard US household/dock power) and 208-240 VAC (higher-voltage dock service). Check your dock or vessel's available power supply before ordering. If you're unsure, contact us for help.
