  • Portable heating and evaporative cooling apparatus
    Publication number: 20030131985
    Abstract: A portable apparatus has a base section that includes a blower, and can be configured for heating or evaporative cooling. By attaching a heating attachment, a gas heating apparatus is provided, and there is no open and/or visible flame. The heating attachment can be replaced with an evaporative cooling attachment, so that evaporative cooling can be performed using the same base with the evaporative cooling attachment. A system of switching pulleys and/or belts to change blower speed, as well as a single switch that operates both devices, is also provided. Thus, a portable heating and evaporative cooling apparatus is provided that has a wide range of industrial application, and that overcomes the related art cost of separate heating and evaporative cooling apparatuses.
