ABSTRACT:
A disposable liquid sterilizer unit incorporates an ultra-violet tube designed to generate radiation at approximately 2537 Angstroms. The unit comprises an elongated cylindrical plastic jacket opaque to ultra-violet radiation concentrically mounted about the tube to provide a chamber between the jacket and the tube for the flow of liquid to be exposed to radiation generated by the tube. The tube extends beyond the ends of the jacket and includes electrical connectors at each end for removably mounting the unit to make electrical connection with electrical connections in a casing. A seal is provided adjacent each end of the jacket against liquid flow from the chamber between the tube and the walls of the jacket to the exterior of the jacket. Inlet and outlet connections for the flow of water to and from the chamber are provided. The tube is double-walled, providing a sealed and preferably evacuated space between the walls to provide thermal insulation between the radiation generating parts (gas and electrodes) inside the inner wall and the outer surface of the outer wall which is exposed to cold water in the flow chamber.
