What is Hydromx®?

Hydromx®, is a revolutionary heat transfer fluid that utilizes Nano-Thermo™ technology. Hydromx® uses nano-particles that are suspended in a stable state to increase the speed of heat transfer, by heating up (or removing heat from) the fluid and transferring energy in a shorter amount of time, thereby requiring significantly less energy.

Hydromx® is most suitable for closed-loop heating and cooling systems where efficiency is achieved by diminishing run-times of associated equipment. Hence, the life of the equipment is extended together with lower maintenance costs.  

The NanoThermo™ technology of Hydromx® increases the heat transfer rate. No matter what the energy source, or how efficient the boiler or chiller is, Hydromx® improves the efficiency of the whole system by transferring energy more effectively.

Furthermore, Hydromx® is specifically formulated to prevent corrosion, calcification and algae in the systems. It is certified under the BuildCert Chemical Inhibitor Approval Scheme to inhibit corrosion of metallic and plastic parts, and prevent scaling up of the system, particularly the boiler.



Hydromx® uses leading-edge Nano-Thermo™ Technology and a protected formulation to improve heat transfer. It rearranges the molecular structure of the fluid improving the heat transfer rate and works in concert with the room/radiator thermostats and the boilers controls to reduce energy consumption.

Hydromx® with its Nano-Thermo™ Technology fills the void between the molecules of the base fluid at nano scale. Thus enhances the heat transfer capability of the fluid.

The NanoThermo™ technology of Hydromx® creates a faster and more homogenous temperature distribution compared to water alone.

Hydromx® in Cooling Systems

In cooling systems, when compared with water, Hydromx® makes heat transfer 35% faster. Which means that transferring the same amount of heat in much shorter time. In cooling systems, efficiency of Hydromx® generates mutual gains in more than one part of the system especially in compressor directly.

Energy efficiency of Hydromx® based on reducing the run time of the compressor. Furthermore, approved records show that Hydromx® increases the required ambient temperature limits for Free Cooling up to 5-6ºC. Consequently, it is possible to achieve up to 35% saving in cooling with Hydromx®. In high controlled environments such as data center application, it was recorded as high as 37% saving.

Hydromx® in Heating Systems

Hydromx® reduces the total runtime of your system by transferring the energy much faster and more efficiently.

In addition to this, the heat lost on flue gas temperature (3°C) is also decreased by Hydromx® usage. Thus, the same amount of energy is transferred much faster, creating efficiency and savings on your energy bill. All of these gains have been proven and reported by Enertek which is a leading boiler R&D company. To this day, systems with Hydromx® have shown a productivity increase of 29% on average.


Corrosion Protection

Corrosion is one of the most common problems that hydronic heating and cooling systems encounter. This specific problem may cause your system to destroy zone valves, tanks, ball & check valves etc.

In order to prevent this issue, corrosion prevention agents are added into the mixture, which in turn decrease the thermal conductivity of the water-based solution. With Hydromx® in addition to the savings you get, your system will be protected against corrosion. Hydromx® efficiency in the field of Corrosion protection is verified by BuildCert certification (DWTAS Industry Standard for the Performance of chemical inhibitors for use in Domestic Hot Water Central Heating Systems and BuildCert regulations) and ASTM-D 1384 standard

Scaling Protection

Domestic water that is high in mineral content (or “hard water”) may cause the buildup or scaling of mineral (calcium) deposits in hydronic heating/cooling systems. Scale buildup reduces system performance in a number of ways. If your system uses water as the heat transfer fluid, scaling can occur in the collector, distribution piping, and heat exchanger. In systems that use other types of heat- transfer fluids (such as glycol, an anti-freeze), scaling can occur on the surface of the heat exchanger that transfers heat to the domestic water. Scaling may also cause valve and pump failures on the potable water loop.

Freezing & Burst Protection

The most common anti-freezing agent that is widely used throughout the industry is glycol. While this agent protects the system against most freezing temperatures, it also seriously damages the thermal conductivity of the fluid within the system. Hydromx® achieves very safe freezing temperatures (-61°C) that protect the system against freezing while providing energy savings. We protect your system against freezing while making your system energy efficient and saving you money.

Bacteria Protection

Another problem which Hydromx® protects your system against is the occurrence of pseudomonas and legionella bacteria. Thanks to its formula, Hydromx® also protects your system against this problem. Our bacterial protection is verified by medical reports.


In order to protect the sustainability of the life on Earth, it is imperative that we decrease the amount of CO2 emissions that is released into the atmosphere. Nowadays, the CO2 emissions which are the single biggest cause of global warming, have become a big threat with the global increase in energy demand.

Hydromx® is one of the greenest projects of the world. The LCA and EPD (S-EP-00633) certifications which are prepared by independent testing and approval organizations show clearly that Hydromx® decreases the CO2 emissions by 25% compared to water. This decrease in emissions thanks to Hydromx® use spikes up to 37% when compared to a water-glycol solution.

It has been verified by the LCA and EPD reports that Hydromx® contributes to the new LEED v.4 standard in three different topics as a green and sustainable solution. These are;


 Hydromx® contributes approximately 10 points for LEED qualification when it is used within new constructions.

According to the 2011 data of the UN regarding the environment, the yearly CO2 emissions worldwide have reached 28.8 Trillion tons. The IEA (International Energy Agency) data suggests that if only 5% of the world used Hydromx® today, the value of the yearly energy savings would exceed 50 Billion USD. This way, 86.5 tons of CO2 would be presented from being released into the atmosphere. These figures equate roughly to 231 million trees.



Nano-Thermo Technology™ of the Hydromx® offers enhanced heat transfer at both the boiler heat exchanger and radiator. The presence of nano particles attribute better interaction within the heat transfer regions and microconvection mechanism due to Brownian motion of nanoparticles in the liquid.

Comparison tests of the heat transfer through Hydromx® with water shows that both fluids subjected to the same heat source, the temperature reached by Hydromx®/Water mixture was approximately 10°C higher than that of the 100 % Water. The difference in total energy transferred to the heat sinks up to and including the steady state period (i.e. after 3870 second from the start of experiment) was calculated to be 37% higher. The quicker response of the Hydromx®/Water mixture gives it an advantageous position in terms of heat transfer when compared to Water alone in both heating and cooling application.*

Recent advances in nanotechnology have led to the combination of stable fluids with nanotechnology and thus the emergence of new generation heat transfer fluids called nanofluids. Nanofluids are nanotechnology-based heat transfer fluids that can flow smoothly in the system, and provide enhanced thermal and physical properties that make them attractive in many applications such as pharmaceutical processes, transportation industry, thermal management of electronics, fuel cells, boiler flue gas temperature reduction, heat exchangers.

When a frost inhibitor (such as glycol) is added to water, the heat transfer efficiency of the system will be worse. In addition, pumping penalties are incurred because of the higher viscosity of glycol. Although widely used as a heat transfer medium, water is not perfect. The high efficiency is due to the special properties of the nanofluid component in Hydromx® makes water perform better. Heat that is produced by the boiler (by burning oil or gas) heats the exchanger first and then the water inside. During this process not all of the heat produced is transferred to the water. Some of this heat is lost up the chimney. So the faster we can heat the water or fluid, the less heat is lost up the chimney. Hydromx®, therefore, provides more efficiency with less energy and decreases the combustion cycles of the boiler which lowers fuel consumption.
