  • Two level electric resistance heater and method of use
    Patent number: 9212451
    Abstract: An electrical resistance heater assembly includes a heater housing forming a channel having a longitudinal axis for a fluid such as air to pass through and a heater support plate forming first and second levels in the heater housing. A first mica board assembly supporting a ribbon heater is mounted to the heater support plate at the first level and a second mica board assembly supporting a ribbon heater is mounted to the heater support plate at the second level. The first level is positioned adjacent an inlet of the heater housing and the second level is positioned adjacent an outlet of the heater housing. The first level and a side of the heater housing form a passageway for air to enter the heater housing and be directed to the ribbons of the second level, thereby allowing air to bypass the heater ribbons of the first level.
