Petrochemical manufacturing facilities widely use Dowtherm to provide heating for reactors, crackers and distillation towers in the production of Linear Alkyl Benzene, Phthalic Anhydride, Dimethyl Terapthylate, Terapthalic Acid and other associated downstream products.

Dowtherm A is a eutectic mixture of Diphenyl Oxide and Biphenyl, which is the most widely used heat transfer fluid in the world. This product can be used in the liquid or vapour phases between 15°C and 400°C and has an atmospheric boiling point of 257°C.

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.

Dowtherm T is a liquid phase heat transfer fluid for moderately high operating temperatures from -10°C to 288°C. It can be used to an extended bulk temperature of 305°C. This product is an economical synthetic replacement for mineral oils to improve efficiency and service life for moderate temperature requirements.
