Our core technology, nanoFLUX is a highly-porous coating that enhances evaporative heat transfer by significantly increasing the density of nucleation sites on a surface. Unlike mechanical and sintered enhancements, nanoFLUX can be applied to internal surfaces and intricate micro-scale structures. By improving two-phase heat transfer from surfaces, nanoFLUX enables heat exchangers to be made that are smaller, lighter and more efficient – and at lower cost.
Applied by a chemical deposition technique, our nanoFLUX metallic-alloy coating results in a micro-porous dendritic surface structure that is typically 5-30 microns in thickness.
nanoFLUX is compatible with a wide range of substrates, including:
The nanoFLUX process is low energy, does not involve high temperatures and is based on environmentally-friendly and low-cost materials. nanoFLUX can be optimised for different refrigerants, operating environments and heat fluxes. This versatile process allows nanoFLUX coatings to be added to heat transfer surfaces of any geometry. Applications include:
nanoFLUX® creates a dendritic structure which forms a web of microcavities on the surface of a substrate. These pores significantly increase the sites for bubble nucleation. This reduces the temperature required to make the refrigerant boil, and allows smaller bubbles to be generated and released from the coated surface. These effects combine to significantly enhance nucleate boiling, dramatically increasing the rate of heat transfer

nanoPROTECT is a protective coating technology that increases the corrosion resistance, durability and high temperature resistance of our nanoFLUX® technology. Fully compatible with nanoFLUX, nanoPROTECT is used in applications in which the surface might be affected by oxidation, acidic conditions or very high temperatures.
nanoPROTECT is also being tested as a potential two phase enhancement for ammonia based industrial refrigeration systems.
