Air Heater

Marathon made air heaters features an open coil of high resistance wire electrically isolated in a stainless steelsheath. Using an open coil for heating is the most efficient type of electric heating and is also the most economically feasible one. As it exposes the maximum heating element surface area directly to the airflow, it provides fast heat uptime and improved efficiency. It design facilitates lower maintenance and easy, inexpensive replacement parts. It is constructed of high grade nickel chromium wire coils evenly wounded on mica sheet, placed in center of an SS304 sheath, and electrically isolated using a layer of flexible mica wrapped inside of sheath. These heaters are widely used in hot air dryer
