HeatX increases heat exchanger performance while inhibiting corrosion & biofouling

Biofouling Shield

Prevents tube blockages and combats the accumulation of unwanted bio-growth. Fouling increases downtime, reduces efficiency, and pollutes the environment.

Corrosion Resistance

Prevents corrosion which weakens and cracks tubes resulting in leaks. Delays rust buildup which disrupts flow and decreases performance.

Erosion Protection

Prevents the pitting and wearing of tubes through metal loss. Remain competitive and reduce energy costs by anticipating erosion before it happens.

Significant Cost Savings

Increases heat exchanger performance while extending system lifetime and time between maintenance and cleaning cycles.

HeatX is currently in use at Hawaiian Electric's Kahe Power Plant, protecting two seawater-fed heat exchangers

HeatX is easy to apply with minimal surface preparation

HeatX is water-based and contains no biocidal compounds. The omniphobic (water & oil repellant) nanocomposite properties create an extremely slick surface that releases bio films & growth.

In addition to being non-toxic and non-VOC-containing, HeatX is non-insular and can function under extreme pressures and temperatures up to 400 degrees Fahrenheit.

Fouling impacts performance

Fouling can reduce heat transfer efficiency of stream power plants and oil & gas refineries significantly. In seawater-fed exchanger trials with Hawaiian Electric, a HeatX-coated chiller was capable of handling 2x heat load when compared to an uncoated, fouled chiller. Downtime for maintenance was reduced from 20 days/year to just two days/year for the 12 months after HeatX was applied.

Performance issues

Plant maintenance costs attributable to heat exchangers & boilers


Reduced heat transfer efficiency from fouling


Reduced annual maintenance down-time with HeatX


HeatX Characteristics

HeatX is an advanced low-surface energy, polymeric coating designed to impart chemical resistance and water & oil repellency to a wide variety of metals and coated surfaces.

Hawaiian Electric Company and Oceanit

Oceanit conducted a case study of HeatX in collaboration with Hawaiian Electric Company (HECO) a major utility company in the state of Hawaii. HECO mainly utilizes shell and tube heat exchangers in their power plants. Learn how HeatX significantly reduced biofouling and corrosion issues for HECO heat exchangers.
