Heat Transfer Fluid

Heat Transfer Fluids and Thermal Oil Duratherm

Technology behind Duratherm

Most fluids will transfer heat with some degree of efficiency, but what really makes the difference is how long it lasts and how clean it keeps your system.

We start with various extremely stable, naturally resilient base stocks such as highly refined, severely hydro treated paraffinic oils and pure silicones. Most fluids stop there, but ours are enhanced with a proprietary blend of additives specific to heat transfer applications for long-term, trouble-free operation.

These aren't just off-the-shelf generic additives; our package is finely tuned and formulated for heat transfer fluids.

Some might say the use of additives is not necessary. However, we invite you to read below and decide for yourself if your system needs the extra protection of Duratherm.

The additives we use

Antioxidants

These are critical to any application that is not sealed from the atmosphere. If you don't have a nitrogen blanket on your expansion tank or reservoir, it is crucial that your fluid contain an antioxidant. Oxidation leads to sludge formation that left unchecked could cause blockages and lead to complete system failure.

Our fluids contain a proprietary, dual-stage antioxidant. See for yourself the difference this additive makes through our Competitive Comparison Report.

Corrosion inhibitors

Most systems at some point in time will have some water contamination. Whether from leaky heat exchangers or drawn from humid air, moisture venting through the expansion tank or oil reservoir can lead to corrosion inside the tank. Our corrosion inhibitors virtually eliminate this risk.

Defoaming agents

During start-up, air can become trapped in a system. Pumping creates air bubbles (foaming) which can lead to pump cavitations, possibly damaging pumps and other system components. Our proprietary additive package contains defoaming agents to help keep air from foaming in the oil.

Seal and gasket extender

High-temperature applications are hard on seal and gasket materials. Our seal and gasket extenders help fight heat damage that can cause premature seal failure. You pay a lot for high-temperature seals, so it pays to make them last as long as possible.

Suspension agents

Some fluids develop carbon and other particulate matter after years of use. Even new systems have things like weld slag and metal shavings that can become trapped in instrument lines or cause problems in other areas. Our suspension agents help ensure particulate is held in suspension and easily filtered or caught in strainers.

Metal deactivators

Some metals used in the construction of heat transfer systems can actually react with the oil, causing premature breakdown. Our metal deactivators ensure compatibility with any system, even those with copper lines, heat exchangers or fittings.
