Description
GWS AquaWave Pro G500, a professional tankless RO system from Global Water Solutions, is a compact, all-in-one 400 GPD reverse osmosis system with a built-in booster pump. It delivers purified water on demand without a storage tank, so it fits under counters in cafés, offices and kitchens. UV Water Systems supplies, installs and services it across Oman.

Why Choose This Tankless RO system in Oman?
Oman’s municipal and well water often runs at 300–1500 ppm TDS, and tanked RO units take up space and need sanitising. A tankless RO system produces fresh water continuously, saves cabinet space and avoids stale stored water.
