The use of metal resistors with predictable thermal inertia makes it possible to generate heat with a high degree of accuracy. In addition they do not pollute their surrounding gas which may, for example, be used to dehydrate medicines, chemicals or food.
For these reasons, modern industries are increasingly turning towards heat generation using resistors.
