Electrically heated thermal microbial drain barrier

摘要: A microbe drain barrier for insertion in the of a sink or like to prevent microorganisms from reentering drain. The includes length thin-walled heat-resistant, electrically non-conductive tubing having heat conductivity axial direction not more than about 3 Btu/hr/ft2 /° F./ft. electric heating means an inner surface temperature sufficient growth microbes thereon. Connector pipes extend axially outwardly mounting pipe such that drainage through is required pass tubing. connector are secured by annular insulating rings which isolate and pipes. low reduces transfer supporting structures, nature serves as insulator coming into electrical contact with water other fluid passing
