THERMO-GUARD® is the trademark we use to distinguish our current line of vertical asphalt storage tanks. Astec Thermo-Guard tanks have features that cut heat loss to an absolute minimum—at a reasonable cost. The tanks are usually built to order and can be configured to suit your exact needs. Many options are available, including the components for mixing.
Vertical tanks minimize oxidation of the asphalt because the surface area of the asphalt in contact with air inside the tank is much smaller than in horizontal tanks. This is especially important for PMAC (polymer-modified asphalt cement), which oxidizes faster because it is maintained at higher temperatures.
Another advantage of a vertical tank is the minimal ground area it occupies. Vertical tanks have smaller footprints than horizontal tanks. You can put four vertical tanks in the ground space occupied by a single horizontal tank.
