Asphalt storage and mix tanks and are equipped with heating coils and/or jackets to maintain the asphalt at the required temperature. Caldera Heat Transfer Fluids are utilized in these heat transfer systems to maintain their content at a viscosity that ensures pumpability and prevents freezing. In comparison to direct fired heating, Caldera Heat Transfer fluids offer cost, safety and maintenance benefits.
It is important to maintain uniform heating across a heater/heat exchanger to prevent coking/fouling. Caldera Heat Transfer Fluids utilized in asphalt plants are thermally stable at high temperatures and possess a high flash point, providing the added benefit of a safer tank operation. In Polymer Modified Asphalt (PMA) or conventional asphalt cement heating, Caldera Heat Transfer Fluids are your best choice to ensure a safe and cost effective asphalt tank operation.
