DOWTHERM™ Fluids - Lower Cost Lifetime

What are Dow High Temperature Transfer Fluids? 

---

Dow Chemical has a long-established history as the industry standard in the highest-quality thermal fluids for process heating and cooling. Dow continues the tradition of premium-performance solutions with their range of high-temperature heat transfer fluids, providing you with a product you can rely on. The high-temp fluid portfolio consists of synthetic organic and silicone-based thermal fluids in the DOWTHERM™ and SYLTHERM™ product lines.
 
A wide range of applications require precise thermal control, and dozens of thermal fluid solutions exist—but not all are created equal. It can be easy to be fooled by some marketing jargon or a cheap sticker price promising "equivalent" performance, but rest assured, there is no equivalent for a Dow fluid. The portfolio of fluid solutions from Dow provides incredibly robust thermal stability and a temperature range from −100°C all the way up to 400°C. From jacketed reactors to heat exchangers and more, the SYLTHERM™ and DOWTHERM™ products provide a stable fluid for temperature control across a wide array of applications.

Breakdown of Immediate vs. Long-Term Cost Benefits

Dow Chemical’s analytical testing process, which gives you an up-to-date snapshot of the fluid life, is one of the biggest benefits of selecting one of these thermal fluids. This thorough lab testing provides a wide profile of all fluid changes to help identify potential concerns with product contamination or runaway thermal decomposition. The best part about this process is the testing is entirely free of charge; getting equivalent testing completed at a lab can cost up to a few hundred dollars.
 
By ensuring your system fluid health is optimum, you can better plan for yearly budgets and proactively schedule maintenance when it fits your timetable, not when a system leak or failure occurs. This approach of finger-on-the-pulse health checks of thermal oils will better serve you in the long run—saving money on testing and required emergency maintenance or entire system fills.
 
You may think you are saving money by purchasing a cheaper thermal fluid, but if the oil change out period is two to five times more frequent, those "savings" quickly lead to a runaway budget.
