What is THERMOPHASE?


THERMOPHASE is a nano-coating applied to heat-transfer surfaces.

It changes the interaction between the equipment surface and the fluid flowing across it–creating a surface that resists fouling and improves heat transfer.



Development of THERMOPHASE


Developed in partnership with the U.S. Navy, THERMOPHASE successfully reduced biological fouling. Early testing also revealed an unexpected benefit: improved heat transfer in heat exchangers—even those free from fouling. This discovery led to further development of THERMOPHASE in collaboration with the U.S. Navy. Enhanced heat transfer became a defining advantage, extending THERMOPHASE’s value beyond fouling control to improved heat exchanger performance.




How THERMOPHASE Improves Heat Transfer


THERMOPHASE changes the interaction between the heat-transfer surface and the fluid flowing across it. This reduces boundary layer resistance—the thin layer of fluid next to the surface that can act as a barrier to heat transfer.

By modifying the surface, THERMOPHASE increases the contact angle of the fluid and changes how the liquid behaves at the wall. This helps disrupt smooth, laminar flow near the surface and promotes greater fluid mixing.

The result is:

  • A thinner thermal boundary layer — heat can move through the fluid more easily.

  • Greater turbulence and mixing — hotter and cooler fluid are exchanged more rapidly near the surface.

  • A higher heat-transfer coefficient — allowing heat to move between the surface and fluid more efficiently.

  • Improved performance even on clean equipment — the benefit is not dependent solely on reducing fouling.

  • Simply put: THERMOPHASE changes the surface so fluid moves and mixes more effectively at the interface. This reduces resistance to heat transfer and allows the equipment to exchange heat more efficiently.




Nano-Coating vs. Conventional Coating


Understanding the THERMOPHASE Difference

When people hear “coating,” they often picture paint, epoxy, or a lining that builds up inside a tube. THERMOPHASE is a true nano-coating that works at the molecular level.


THERMOPHASE forms a self-assembled monolayer—a single layer of molecules that chemically bonds to the heat transfer surface. It modifies the surface where water meets the metal, without creating the thick film associated with conventional tube linings..


Conventional film-forming coatings cover a surface with a separate layer of material. Their thickness and thermal properties influence how heat passes through that layer.

THERMOPHASE works through molecular surface modification. Its bonded nano-coating interferes with the attachment of biological and inorganic fouling and is designed to reduce resistance to heat transfer at the water–surface interface.

THERMOPHASE forms a molecular monolayer, rather than a bulk lining. Describing it as a nano-coating means there is a surface layer—but that layer is molecular in scale. It should not be confused with a thick deposit or an accumulation of coating material inside the tube.
Heat exchanger performance depends on how efficiently heat moves across the tube surface. Fouling and resistance at the water–surface interface can hinder that process. THERMOPHASE addresses these conditions through a molecularly thin surface treatment designed to reduce fouling and improve heat transfer.
