DOWTHERM™ RP

Diaryl Alkyl Thermal Fluid for Liquid Phase Systems between 0°C and 375°C (32°F to 710°F).
Product Overview

DOWTHERM™ RP is a high-performance thermal fluid for non-pressurized liquid phase systems between -20°C and 350°C (-4°F to 660°F).

DOWTHERM™ RP advantageously degrades to low molecular weight compounds, reducing the need to clean out build up of high weight products.

DOWTHERM™ RP exhibits good low-temperature properties, reducing the necessity of heat tracing and low temp start-up concerns while also exhibiting excellent high temperature stability.
