Heatec Reaction Tank

Overview

Heatec reaction tanks are used for making modified asphalt cement, particularly rubber modified asphalt using crumb rubber. They are available in multiple sizes and configurations. They can be portable or stationary, vertical or horizontal, and electrically heated or hot oil heated.

Our most popular are portable holding tanks. One compartment in the portable holding tank contains fresh mix for a speciﬁed time while aged mix is used out of another compartment to make Hot Mix Asphalt (HMA). Each compartment has an auger mounted horizontally in its lower compartment. The auger agitates the mix to keep crumb rubber in suspension. The augers in each compartment operate independently. A level ﬂoat system diverts the hot oil ﬂow if the asphalt-rubber drops below the top of the heating coils.

The portable reaction tank can be a single, double, or triple compartment design. Each compartment has individual controls for level and temperature. Blue smoke control, folding walkways and plant supply pumping/metering systems are all inclusive. Axles are provided per permitting requirements.
