Frequently Asked Questions

While this is a common engineering question, it is also a misapplied question for nanofluids. Specific heat is measured with the fluid static. HVAC systems operate with the fluid in motion and better yet, the fluid in turbulence. Nanofluids outperform other fluids when in turbulence.

Also, some nanofluids (including Hydromx) are non-Newtonian which means their characteristics change under stress. Hydromx is a sheer-thinning nanofluid where its fluid pressure drop improves as it is placed under stress.

Yes, Hydromx is a perfect solution for these outdated systems. Draining and filling water loops is labor-intensive, increases corrosion potential, and dumps toxic inhibitors down the drain into water treatment plants.

The LCA and EPD have verified that Hydromx contributes to the new LEED v.4 standards in three categories: Optimizing Energy Performance, Building Lifecycle Impact Reduction, and Building Product Disclosure and Optimization.

Hydromx is a glycol based efficient heat transfer fluid and thus offers complete system protection from corrosion, scaling, calcification, algae, freezing and bursting.

Hydromx is certified nontoxic by FDA regulations. Both Hydromx’s ethylene and propylene versions carry the highest available safety rating from NSF for toxicity. Hydromx-EG (ethylene) carries an NSF HT-2 rating. Hydromx-PG (propylene) has an NSF HT-1 rating. Documentation of these ratings can be found at nsf.com (search for “Hydromx.”)

Hydromx is available in two glycol formulations: ethylene (Hydromx “Red”) and propylene (Hydromx “Blue.”). Hydromx also includes the energy-saving, non-abrasive, non-toxic, nanomaterial along with corrosion and biological inhibitors

The existing heat transfer fluid in a closed-loop system is drained and replaced with Hydromx. One pipefitter can complete installation in usually one to two days.

Hydromx will arrive on-site in concentrate to be mixed with tap water per Hydromx’s installation instructions.  Hydromx challenges the industry to identify another energy-saving product that is as fast and easy to install with similar energy-saving benefits.

Reports from Argonne National Labs in 1997 describe early nanofluid research as a perceived increase in the surface area of the heat transfer fluid. Hydromx operates in a similar fashion as its Nano-Thermo® technology delivers a perceived increase of the surface area of a fluid beyond the surface area of the fluid in contact with the heat exchanger.

Hydromx improves the heat transfer of the entire fluid to the heat exchanger wall. The fluid in the center of the pipe improves its thermal conduction to the heat exchanger wall.

As a result, HVAC systems that operate with Hydromx require less energy consumption to achieve the same performance when compared to the same system running on water or a water/glycol blend. By improving the system efficiency, Hydromx reduces power consumption, saves money, and reduces carbon emissions into the atmosphere.

All HVAC systems consist of multiple heat exchangers. It has been academically proven that, during heat transfer, nanofluids increase the “active surface area” of the heat transfer fluid. As a result, the efficiency of the overall system improves as if the heat exchangers have become theoretically larger.

Nanofluids increase the active surface area of the medium by evenly suspending nanoparticles. See this white paper for a more detailed discussion of the science of nanofluids.

A nanofluid is a fluid containing stably suspended nanoparticles with dimensions smaller than 100 nanometers (one billionth of a meter). The term “nanofluid” was first used by Choi (1995) to describe this new class of nanotechnology-based heat transfer fluids with enhanced thermal properties. In the past 10 years, the US Government has co-authored patents on two different nanofluids.

Hydromx is an energy-saving nanofluid. Hydromx uses Nano-Thermo® technology to evenly suspend nanoparticulate in a glycol-based solution. As a result, Hydromx significantly improves the heat transfer of closed-loop hydronic heating and cooling equipment. Hydromx has been verified by utilities and third parties to reduce power consumption by 20-35%.
