Heat Transfer Fluids Calculator

FLUIDFILE™ Software is designed to enable fast, efficient evaluation of the properties and performance of Dow heat transfer fluids under your actual system conditions, and in the units of measure you prefer. It makes choosing the right fluid easier and more convenient for both experienced professionals and first-time system designers.

You won’t need prior experience with Dow Heat Transfer Fluids to obtain the information you need to select the right fluid. To assist in your fluid decision-making, FLUIDFILE provides an overview of our fluids line, guidance in choosing a fluid chemistry including application information, plus profiles of the individual fluids.


About Dow Fluids

Our glycol-based fluids are for use in water-based systems operating as high as 175°C (350°F).

Glycol based fluid graph

Extend the life of your system with our Low-Temperature Heat Transfer Fluids

  • High-quality heat transfer fluids that can enable your system to perform for 20 years or more
  • Low upfront investment and low maintenance and operating costs
  • Fully formulated with industrial inhibitor packages which provide passivation of metal surfaces, neutralization of degradation compounds and thermal oxidative stability
  • Protects system components against corrosion and scaling that can lead to costly system downtime
  • With nearly 80 years of expertise and as the oldest back-integrated supplier of glycol-based heat transfer fluids, Dow is a supplier you can trust and depend on.

 

Ethylene Glycol Fluids (EG)

In most applications, EG-based fluids are preferred because of their lower cost as well as lower viscosity and resulting superior heat transfer efficiency and pumping power. For cold systems, you can use ~2% less EG than PG to achieve the same freeze protection.

Propylene Glycol Fluids (PG)

PG fluids are most commonly used in applications requiring low acute oral toxicity, in food applications or where incidental contact with drinking water is possible. In some areas, use of PG fluids is required by local regulations.

Extend the life of your system with our High-Temperature Heat Transfer Fluids

  • High-quality fluid for less than 1% of system cost
  • Maximize planned operating temperature
  • Reduce long-term system degradation and replacement costs
  • Enabling your system to perform 20 years longer

 

DOWTHERM™ synthetic organic fluids:

  • Each DOWTHERM™ fluid offers outstanding thermal stability for efficient heat transfer, extended fluid life, and optimum operating economics.
  • All DOWTHERM™ fluids have vapor pressures lower than steam and three fluids are designed to be used in non-pressurized systems.

SYLTHERM™ silicone fluids:

  • SYLTHERM™ fluids are essentially odorless and low in acute oral toxicity.
  • Provide excellent heat transfer performance and can provide exceptionally long service
  • In the U.S. SYLTHERM™ fluids are not listed as reportable under SARA Title III, Section 313.
