Dowtherm is the preferred product for use in used oil recycling and recovery since this application demands a reliable fluid which can operate at temperatures in excess of 330°C in the liquid phase with low pressure. The fluid withstands very large DT continuously and is engineered for thermal stability so as not to itself crack or degrade during processing of the used oils.

Dowtherm RP is a liquid phase heat transfer fluid with an operating range of -20°C to 350°C. This product minimizes the risk of fouling, scaling and coking by preventing the formation of high boilers upon thermal degradation.
