WBS R1.2-RK EXT Automatic Touchless Basin Faucet
The automatic touchless basin mixer WBS R1.2-RK EXT is a concealed basin mixer with a fixed spout, integrated electronics and a solenoid valve located directly in the body of the mixer. The two-hose version is equipped with an accessible mixer that allows for easy manual adjustment of the desired water temperature. The concealed concept requires construction work in the wall to install the installation kit, resulting in a clean, minimalist design with a minimum of visible elements.
The device is equipped with an optoelectronic sensor with an adjustable long range, which ensures reliable touchless control. The water flow starts automatically when hands are placed in the sensing zone, and turns off 1-2 seconds after their removal. The sensing range is set automatically after connection and can be adjusted later, along with other parameters, via the remote control.
The faucet offers the option of setting automatic hygienic flushing and thermal disinfection flushing, which contributes to maintaining a high level of hygiene in water distribution systems. The device also automatically archives operating statistics, which allows for effective monitoring of usage and supports optimization of operations in public and commercial spaces.
