  • Patent number: 10184495
    Abstract: A portable air movement apparatus with improved air blending is provided, having a housing, an air generator, an air outlet, and an ambient air passageway through the housing of the device. The impeller and other components, such as the heating element, are disassociated from the location of the air outlet, allowing for the ability to use more than one air outlet, which serves to spread the air stream over a greater area. The disassociation of the impeller and other components from the air outlet also minimizes the housing size required near the air outlet, thereby allowing ambient air to be entrained in the air flow produced by the apparatus. As such, the apparatus moves more room air through the apparatus and more rapidly blends the air into the entire area or room.

  • Patent number: 8447176
    Abstract: A space heater and a method for generating a convection flow of air through chimneys of the space heater for heating an area adjoining the space heater is provided. The space heater includes a first panel, a second panel, and an element having one or more heatable surfaces. The second panel is coupled to the first panel and the element is located therebetween to define the chimneys between the first panel and the second panel. The element has the one or more heatable surfaces located within the chimneys. When activated, the one or more heatable surfaces create thermal energy for generating heated air within the chimneys, the heated air flowing by convection substantially upwardly through the chimneys to provide the heated air to the area adjoining the space heater.

  • Publication number: 20130032308
    Abstract: A method of heating or cooling a room of a building includes providing supplemental warmer or cooler air to the room with an inline duct supplemental heating and cooling device mounted along an air duct that supplies the room with air from a main furnace or cooling unit associated with the building. A thermostat is used to set a desired temperature for the room, and a controller of the supplemental heating and cooling device is in communication with the thermostat, and activates an electric heater and/or fan as appropriate to warm or cool the room as needed. When the device is used to cool the room, the fan may be operated to draw cooled air through the duct from the main cooling unit and/or from other areas in the building that are linked via ductwork.

  • Publication number: 20120328270
    Abstract: An explosion proof forced air electric heater is designed to supply heat to hazardous areas where the atmosphere contains readily combustible gases, vapors or dust particles. The heater employs an air mover which forces air through a metal heat sink with strategically placed electric heating elements. The terminal ends of the heating elements extend into a sealed and encapsulated explosion proof containment chamber which is connected to a centralized explosion proof enclosure. The explosion proof enclosure contains the control features and the electrical connections of the heater along with external accessories. The heating cycle is controlled via an electronic control circuit. The electronic circuit controls the process heating temperature, air mover operation, heating element operation, temperature measuring device operation, and monitors the total operation time of the heating elements while providing process failure feed back to the operator.
