There are over 80 million electric clothes dryers in North America with the majority of them operating on mechanical, timer-based control settings with no humidity sensing capabilities. These clothes dryers use simple timers to control the duration of drying cycles and, due to the lack of humidity-sensing features, continue to operate even after the clothes are dry. As a result, clothes are routinely over-dried, wasting millions of kilowatt-hours of energy each year. The TrickleStar© DryerSaver™
is the first energy-saving, retrofittable power management device for electric clothes dryers that switches off the dryer when the clothes reach a specified level of dryness. Ideal for older electric clothes dryers that only use timer-based controls or even newer models with older temperature and humidity sensors. Even new models with humidity sensors often become inaccurate as sensors wear out or foul in the hot, aggressive climate inside the clothes dryer.
