Gjosa - Multiple application water-saving technology

The Gjosa solution is a patented technology saving up to 79% of water & energy used during daily routines while providing a unique and pleasant experience.

The solution has two areas of application: daily showering and salon hair washing. Each of these may use a specific derivative of the Gjosa technology. Jet-Fusion provides a unique showering experience with water droplets being 10 times smaller than standards showers. Other features include its high water flow velocity and its optimal rinsing and wettability. The water and energy used with Jet-Fusion is 25% less than with standard showers. For hairwashing application, In-Flow (the second derivative of the Gjosa technology) harmoniously mixes water and shampoo together. When in use, In-Flow uses only 2L per minute compared to industry standard of 10 liters per minute. It shares features with Jet-Fusion such as the smaller water droplets and high water flow velocity.
