How Heating Element Works On Hand Dryer

A hand dryer's heating element operates on the same concept as the coil in an electric heater. It consists of an un-insulated metal conductor and when an electric current passes through an electric heater, its resistance to the flow of electricity makes it heat up. It burns out when the coil gets too hot. Among the conditions that can cause insufficient airflow are elevated temperatures in the element compartment, failure of safety devices and a power surge.

How an Electric Dryer Works:

  •  The hand dryer uses the same technology as similar to automated doors. The optical sensors in the dryers bounce back the light from the skin to the receiver.
  •  A hand dryer heating element heats the air and evaporates water on hands, Once they’re triggered. Nichrome is used as a heating element has a melting point of as high as 1400-degree Celsius.
  •  By cooling technology a few hand dryers eliminate the water. And, hand dryers are eco-friendly and easy-to-install.

Heat Protection Devices:

An electric hand dryer, four components are wired into the circuitry to prevent damage in the case of insufficient airflow. Both the high limit thermostat and cycling thermostat are designed to switch off power to the element when the temperature exceeds a pre-set limit and to turn it back on when the temperature drops. And, thermal fuses protect both the motor and the heating element. The hand dryer is designed to blow Hot Air. If either of these fuses blows change, it could be a sign that you need to relocate the hand dryer.
