Touch-free towel and soap dispensers can be a good match for many facilities because they can be adjusted based on occupant use. Product portion control is a big advantage with touch-free. Much product waste, especially in the case of paper towels, can be prevented by allowing only a certain amount of product to be dispensed per sensor activation. When determining dispensation preferences, keep in mind the building occupants and waste considerations, and plan maintenance such as waste pick-up, accordingly. In a high-traffic restroom, multiple dispensers should be available, delays should be short and longer lengths are recommended. In an office building, occupants may not need as much paper towel, and the delay can be longer. Ideally, appropriate time delays between sensor activations should also help cut down on product waste.
