  • Patent number: 8311402
    Abstract: A heater system is provided that includes a plurality of carrier members, each carrier member defining an inner periphery surface, an outer receiving portion, and connecting portions. A plurality of resistive heating elements are disposed within the outer receiving portions of the carrier members, and end fittings are disposed proximate the carrier members and the resistive heating elements. A cover is disposed around the carrier members and the resistive heating elements, and the inner periphery surfaces of the carrier members are adapted to transfer heat to a target and the connecting portions are adapted to be secured to at least one of an adjacent carrier member and a heating target. In one form, at least one set of a carrier member and a resistive heating element are resiliently movable such that the heater system provides tactile feedback to an installer that the heater system is properly installed around a target.
