HTF Compact most efficient nanofluid, all hydronic systems contain a fluid as a medium to transfer heat. That fluid in most cases is water. In some cases, where freeze protection is needed, it is a water and glycol mixture. In the past, water has been the most efficient heat transfer fluid. With advances in nanotechnology, that has changed. By successfully adding nanoparticles into a transport fluid we now have a heat transfer fluid more efficient than water, and far more efficient than any glycol/water mixture.

Although water is thought to be an effective heat transfer fluid, it can cause multiple setbacks to systems such as corrosion, freezing, calcification and bacteria generation.  HTF Compact helps solving these issues and it has been installed already in relevant applications. Usually, any system using glycol for freeze protection requires the oversizing of equipment by up to 20% to compensate for the decrease in heat transfer associated with glycols. HTF Compact greatly improves the heat transfer of these systems and removes the energy penalty that is correlated with any water/glycol mixture. The percentage of glycol will vary, depending on the climate zone.






HTF Compact can be added to existing system coolants or base fluids without having to drain the entire system. HTF Compact is added to water, ethylene glycol or propylene glycol in heating, cooling and thermal solar applications among others. HTF Compact can operate at temperatures between -40° C (-40° F) and 106° C (225° F) at atmospheric pressure. HTF Compact is manufactured with corrosion inhibitors and will last as long as the base fluid. The particle size in HTF Compact is 6,000 times smaller than trace minerals found in regular tap water. Therefore, the particles will not get caught in the smallest of hydronic system strainers/filters.

It is easily installable and durable. It is only required to replace 5% (v/v) of the circulating fluid in your hydronic system with our HTF Compact.


The stability of the nanofluid is fundamental for the performance of the product: well separated nanoparticles have a higher surface exposed and therefore a higher heat transfer efficiency. The use of tap water can pose a great obstacle to stability. The presence of calcium and magnesium salts, accountable for the hardness of the water, leads to aggregation and eventually precipitation of the nanoparticles. Ca2+ and Mg2+ ions interact with the surfactant (present in the nanofluid) and compensate part of the surface negative charge characteristic of the nanoparticles that consequently repel themselves with lower force, allowing occasional collision and aggregation. The hardness of the water can vary greatly between even very geographically closed places and can range from 0°f (very soft water) to over 40°f (very hard water). Our WES solves the problem in a way that is tailored for the water used by the specific client. Following the shipment from the client of a sample of the water used in his system, TCT Nanotech will analyze its quality and will tune the amount of WES to pour into the system for a proper functioning of HTF Compact. Thanks to the TCT Nanotech R&D team, our product is the only one on the market to have found a solution for this problem and to guarantee the proper functioning of the nanofluid even in systems in which the base fluid is made, totally or partially, by tap water. WES is a water-based solution, perfectly safe for the system, the operator and the environment, it’s easy to install in the system and does not require any modification. An easy solution to a difficult problem.


  • HTF Compact enhances heat transfer resulting in higher and faster heat loads being transferred between fluids.
  • Energy savings of 30% (kWh consumed at a defined installation).
  • HTF Compact operation results in an increase in chiller compressor direct efficiency.
  • HTF Compact decreases the run time of compressors and hence, creates savings on lower maintenance requirements Greenfield projects can benefit from streamlined equipment sizing and therefore, lower investment costs.


  • HTF Compact reduces the total runtime of your system by transferring the produced energy created much faster and more efficiently.
  • Due to better heat transfer capabilities, heat losses are decreased (lower temperature at flue gases)
  • When introducing HTF Compact, savings are created on lower maintenance requirements. Circulating flows are lower resulting in reduced maintenance frequencies.
  • Greenfield projects can benefit from streamlined boiler equipment sizing, smaller piping systems and therefore, optimized lay outs and lower investment costs.


Introducing HTF Compact to an existing system is straight forward. HTF Compact can be applied to systems in service (without taking them out of operation). It is pumped into the system by means of a manual/electrical dosing pump. It is only required that a connection point/nozzle with a manual valve is available.


HTF Compact does not alter the normal operation philosophy/procedures at a site. Actually, the operators will notice that the system can either process higher heat loads or equipment will run smoother. TCT Nanotech provides guidelines on what process variables to monitor in order to assure the product is properly monitored by simple means of water chemistry control.


HTF Compact in solution with water and glycol can be disposed as regular coolant. No impact nor special consideration adding cost to disposal of the base coolant is foreseen.
