Hot box at BCI emulsion plant


A hot box (also called a melter) is used at asphalt terminals and at emuslion plants. It is used to re-melt buckets of solidified asphalt that has been collected from drippings and samples used for testing. It has hot oil heating coils in its bottom and sides.

The box has a hinged lid and will accommodate up to six five-gallon buckets, which are placed upside down in the box. The box can melt the asphalt in all six buckets in about 15 minutes.

When the asphalt becomes liquid it collects in the bottom of the box where it can be pumped into storage tanks.
