Astec Blue Smoke System


Blue smoke is the leading cause of odor complaints at an asphalt facility. Reducing fugitive blue smoke emissions will decrease the level of detectable odors from your facility and improve your work environment as well as community relations.

Blue smoke is the result of asphalt fumes condensing upon contact with cool ambient air. To minimize emissions, it is necessary to control the condensation of the asphalt fumes. 

The Astec Blue Smoke System includes a network of scavenge ductwork and collection points designed to control emission opacity by limiting the escape of vaporized asphalt fumes into the atmosphere.
