Superior smoke generators are a cost-effective method for finding sources of surface inflow causing wet weather sanitary sewer overflows. The company offers both classic smoke candles and smoke fluid systems, plus smoke blowers engineered for smoke testing. Classic smoke candles are available in sizes from 30 to 500,000 ft. The systems use a proprietary insulated heating chamber with stainless steel injector to maximize dry smoke output and produce high-quality liquid-based smoke at a good value.
