What is dowtherm fluid?

DOWTHERM* A heat transfer fluid is a eutectic mixture of two very stable organic compounds, biphenyl (C12H10) and diphenyl oxide (C12H10O). DOWTHERM A fluid may be used in systems employ- ing either liquid phase or vapor phase heating.

What is dowtherm used for?

The most thermally stable synthetic organic heat transfer fluid, designed for high temperature heat transfer applications up to 400°C (750°F) as well as to collect, transport and store heat in CSP systems. This fluid can operate in either liquid or vapor phase.

What is the meaning of dowtherm?

heat transfer fluid
Dowtherm A is a eutectic mixture of Diphenyl Oxide and Biphenyl, which is the most widely used heat transfer fluid in the world. Dowtherm T is a liquid phase heat transfer fluid for moderately high operating temperatures from -10°C to 288°C.

Is dowtherm J flammable?

At ambient pressure and temperature, Dowtherm is not flammable because it has a flashpoint of approximately 400 Degrees F.

What color is Dowfrost?

fluorescent yellow
DOWFROST™ HD has a fluorescent yellow color and can operate at higher temperatures than regular DOWFROST™. DOWFROST™ HD is suitable for use in environments between -50°F and 325°F (-45°C and 160°C). DOWFROST™ HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F.

What is the maximum temperature of Dowtherm A?

DOWTHERM™ A from The Dow Chemical Company is a heat transfer fluid suitable for non-pressurized liquid phase systems with a maximum temperature of 550°F (288°C). DOWTHERM™ A is a eutectic mixture of two very stable compounds.

What makes a heat transfer fluid a Dowtherm?

DOWTHERM* A heat transfer fluid is a eutectic mixture of two very stable organic compounds, biphenyl (C 12 H 10 ) and diphenyl oxide (C 12 H 10 O). These compounds have practically the same vapor pressures, so the mixture can be handled as if it were a single compound.

Which is better dowtherm4000 or dowthermsr-1?

Compared to DOWTHERMSR-1 fluid, DOWTHERM4000 fluid has a higher maximum operating temper- ature, higher reserve alkalinity and greater thermal stability. While DOWTHERMSR-1 fluid is considered the standard ethylene glycol-based fluid for most applications, fluids are less viscous than propylene DOWTHERM4000 fluid is specified

Which is a stable compound in Dowtherm A?

DOWTHERM™ A is a eutectic mixture of two very stable compounds biphenyl – C12H10 diphenyl oxide – C12H10O with practically the same vapor pressures – suitable as a indirect heat transfer fluid for
