Heat Transfer Fluid Additives

Heat transfer fluids are the lifeblood of thermal systems—moving heat efficiently while protecting equipment. Dober develops high-performance additive technology that helps heat transfer fluid manufacturers deliver reliable corrosion protection, scale control, and long service life across demanding operating conditions.

Built for long-term system reliability

Dober works closely with heat transfer fluid blenders and manufacturers to supply technologically advanced chemistries designed to:

Protect critical metal surfaces from corrosion
Prevent scaling and deposit formation that reduces heat transfer efficiency
Support consistent performance in commercial and industrial systems

Where our technology is used

We support additive packages and blending syrups for commonly used heat transfer fluids across a wide range of applications, including:

- HVAC systems
- Process heating and cooling
- Stationary engines (diesel power generation)
- Solar thermal

Advanced chemistry options

Based on criteria provided by our blending partners, Dober supplies additives for the industry’s most widely used heat transfer fluids. Our latest technical advancement includes an organic acid technology (OAT) HTF additive designed to be cost-effective and to outperform traditional chemistries in relevant systems—particularly where aluminum protection is critical.

Industries we serve

- Automotive
- Energy, oil, and gas
- Industrial and commercial HVAC
- Manufacturing

Expertise beyond “glycol + water”

Glycol-based heat transfer fluids are more than simple glycol-water solutions. Dober is an industry leader in developing and testing HTF chemistries that help prevent corrosion and scaling. Our portfolio includes conventional phosphate-based packages as well as newly developed OAT formulations for aluminum systems.

technical expertise

Our team has a wide range of tools at its disposal and the necessary technical expertise to underpin technical support efforts.

Whether it's testing your glycol, troubleshooting any issues that may arise or facilitating annual check-ins, rest assured that we'll have your back. At right, you can find a sampling of some of the testing the Dober R&D team executes in the lab. 

With decades of formulation experience in the performance fluids space, the Dober R&D team has delivered strong results based on a philosophy of innovation and forward thinking. This is especially important when it comes to testing of coolants for battery electric vehicles, fuel cell vehicles and electrolyzers for hydrogen production, as ASTM testing standards have yet to be finalized

What does that mean? You need an R&D team that is able to execute testing strategies when a template for that testing doesn't exist. Learn more about Dober's testing capabilities in the performance fluids space
