Improved efficiency of tumble dryers has developed because of increased attention to environmental pollution. The efficiency of a dryer is determined by an "energy factor" coefficient which measures the Kg of clothing per Kilowatt-hour of electricity. The operating concept consists of a rotating drum (50/100 rpm) with a heated air flow moving over clothes. The two types of dryer provide energy in different ways:

  • electric dryers have heating elements
  • gas dryers use a gas burner

Both types of Dryers are subject to requirements of silent running and high efficiency with an expectation of long service life. A small electric motor (commonly a single-phase induction motor) drives a drum while a ventilating fan provides the hot air through the clothes.
