Abstract

An unplumbed sterilizer includes a heater having an electrical heating element disposed within a thermally conductive heater body. A conformable thermally conductive heat transfer plate is mounted between a mounting surface on the heater body and a heating surface on the sterilizing chamber. The heat transfer plate is effective to maintain a continuous mechanical contact between the heating and mounting surfaces. Further, a temperature sensor is attached to the heater body. By regulating the electrical power to the heating element as a function of the temperature of the heater body, the power applied to the heating element is maintained within specifications. Further, the heater body is mechanically attached to the sterilizing chamber by a single fastener resiliently applying a clamping force through the center of the heater body. In addition, the heater body is accessed simply by removing a cover plate from the outer body of the sterilizer.
