Typical Heatec fume condenser.
Our fume condensers are used in vents of asphalt tanks to condense gas vapors (known as blue smoke) present in liquid asphalt. Condensing the vapors turns them into a liquid that drains back into the tank. This greatly minimizes the release of pollutants into the atmosphere.
The condensers have a number of tubes with external fins. The tubes are cooled by ambient air circulating through the fins. Thus, gases exiting the tank are cooled as they flow through the tubes. The cooling causes vapors to condense and drain back into the tank.
Condensers can be configured in a variety of ways. Some plants use one condenser per asphalt tank. Others allow multiple tanks to share one condenser.
Two models are available: one is rated at 200 gpm and the other is rated at 300 gpm. The ratings relate to the tank fill rate, which is equal to the gpm output of the unloading pump.
