About GREENJET
GREENJET is a company founded in Vienna in 2021 that develops and sells patented water-saving technology for showers and washbasin faucets. The patented two-phase technology with controlled air admixture reduces water consumption by up to 66 percent and simultaneously lowers the energy demand for hot water, at constant water pressure and without retrofitting. The portfolio includes the GREENJET water-saving nozzle for shower faucets, the TÜV Austria certified GREENJET washbasin faucet as well as the GREENJET test kit for measuring the actual savings on site. Retrofitting takes only a few minutes without tools and without interfering with the installation. The products are manufactured locally (Made in Austria) and used internationally across Europe, including in the hotel industry, healthcare and public facilities. References include Park Inn by Radisson Berlin, Ibis Styles Linz, Derag Living Vienna and Hotel Zimba Schruns.
