Hot Air Heater
摘要:
A hot air heater includes heating wires (3a, 3b) wound around an insulating fire-resistant support in such a way that currents flow reversely through the heating wires (3a, 3b) in order to compensate electromagnetic waves generated from the heating wires (3a, 3b), thus reducing electromagnetic waves.
