The first electronic roll towel system to offer totally touch free dispensing. The only thing you touch is your personal towel. The towel is stored fully protected inside the dispenser until you request service by passing your hand or arm near the sensor. There are no levers, buttons or cranks to touch. This is particularly important in public restrooms, food preparation and healthcare environments where maintaining proper sanitary conditions is essential. The Wave 'n Dry® dispenser helps to prevent cross contamination and reduced contact with potentially dangerous bacteria. Sensor is pointed downward to eliminate sensitivity issues and allow for flexible installation. Batteries can be installed directly into the battery holder. Controls usage with adjustable towel and delay settings. Stub roll feature eliminates service interruptions. Accommodates a variety of controlled towel choices in DublSoft®, EcoSoft™ and EcoSoft™ Green Seal™ brands.
