The Gelan series of electronic faucets features a single control knob: press to turn on the water, and rotate to adjust the water temperature. This makes it easy for users to maintain the proper temperature and minimize the waste of water resources caused by repeated adjustments. The faucet uses the kinetic energy of water to generate electricity and has an integrated LED light that indicates water temperature so children and the elderly can see whether the water temperature is appropriate and avoid accidental burns. The faucet is made of copper with a low lead content and the surface finish is a glossy black, PVD electroplated for durability and a long-lasting shine, keeping the faucet look like new for years to come.
