Oceanit’s HeatX and HeatX+ treatments are advanced nanocomposite surface treatments for heat exchanger and condenser performance efficiency. HeatX treatment reduces maintenance needs, downtime-costs, and improves efficiency by mitigating bio-fouling and corrosion.
The HeatX family of omniphobic (oil & water repellent) coatings was a co-development project with partners from the U.S. Dept of Energy, national labs, academia, and more. HeatX repels bio-fouling (both micro and macro-organism) growth on the tubular and metallic surfaces of all varieties of heat exchangers which are vulnerable to corrosion, pitting, and fouling.
Due to the extremely slick, low surface energy of the HeatX surface treatment, tubular surfaces are endowed with extremely low-friction properties that minimize organisms’ ability to bind on the surface. HeatX does not contain any harmful biocidal compounds that are commonly found in other anti-fouling coatings/epoxies, so the resulting surface is inert to both water and oil-based substances. Rather, the slick surface ,combined with flow through the tubular, repels organisms from adhering to the tubular surface.
HeatX is functional at less than 2mil DFT and is non-insular, meaning it does not affect the overall heat transfer function of the heat exchanger unit. In addition to releasing fouling from surfaces, HeatX also prevents corrosion of heat exchanger surfaces and prevent erosion pitting and other material losses from surface substrates. By preventing the build-up of insulating corrosion or bio-fouling, HeatX preserves the efficiency of the heat exchanger, saving a large amount of maintenance downtime and costs for the operator.
HeatX coating is a water-based formulation, non-VOC and non-toxic after curing. It can even be applied to unprepared, corroded surfaces and still achieve the full benefits.
