Abstract:
A seal for an opening defined by a wall portion of a pressurizable tank, said tank contains desiccant for drying a gas passed through the desiccant in which an elongate antenna for carrying microwave energy to the desiccant for regeneration of the desiccant extends from an interior portion of the tank through the opening to an exterior portion of the tank, comprising:an insulator having an interior surface for receiving engagement with the antenna proximate the opening of the tank; said interior surface of the insulator defines a shape such that a distance between opposing portions of the interior surface of the insulator reduces as the insulator extends in a direction through the opening toward the exterior of the tank for receiving engagement with the antenna; said antenna which engages the interior surface of the insulator has a cross section dimension which reduces in size as the antenna extends in the direction through the opening toward the exterior of the tank; and an external surface of the insulator which opposes the interior surface of the insulator in which the external surface is positioned between the interior surface of the insulator and the wall portion of the pressurizable tank which defines the opening of the tank.
