Proprietary heat panel technology offers thermal performance and efficiency. The pinpoint laser welds of the Heat Optimized Thermodynamic (HOT) Panel design facilitate maximum swirl of the heating medium in operation. According to the manufacturer, that provides better transfer of heat into the vessel for less energy. The heat panels can be used to keep transported crude oil warm for complete drain-out. They also are suited for food product transport to preserve properties or purity.
