Superior Signal smoke testing systems help reduce wet-weather sanitary sewer overflows and surface inflow. Smoke candles, fluid and smoke blowers are designed to smoke-test sanitary sewers quickly, efficiently and economically. Blowers can be used with smoke candles or fluid to detect common sources of inflow and other faults. Superior 3C Classic smoke candles produce a volume of 40,000 cubic feet of smoke in just three minutes. Join multiple smoke candles together to create larger volumes of smoke visible for a longer period of time. Systems offer a liquid-based alternative for mainline sewer inspection, with a heating chamber with stainless steel injector to maximize dry smoke output, producing a highly visible, liquid-based smoke. 800-945-8378; www.superiorsignal.com.
