Touch free dispensers offer the maximum possible hygiene when dispensing. A simple wave of the hands under the dispenser and the latest infrared sensing technology instantly delivers the right amount of soap. Powered by 4 D-Cell batteries which will provide up to 5 years of operation in typical usage conditions the dispenser is also guaranteed for the same period. The dispensers are protected by BioCote®, incorporated during the manufacturing process which inhibits the growth of a broad spectrum of bacteria and moulds. BioCote® does not rub-off and is effective for the lifetime of the dispenser.
