• Operating conditions such as high heat, low pH, and high-velocity flow, which accelerate fouling.
• Contaminants and microorganisms like airborne pollutants and bacteria, which form films on surfaces.

These issues can cause reduced heat transfer, local hot spots, and even equipment breakdowns. Frequent repairs and higher maintenance costs often follow.

Strategies to Minimize Fouling

To minimize fouling, I recommend understanding its mechanisms—mechanical, chemical, or biological. Regular cleaning and inspections are essential. Optimizing operating conditions, such as controlling fluid velocity and temperature, also helps. Using inhibitors or biocides prevents chemical reactions and biological growth. Advanced coatings and corrosion-resistant materials further reduce fouling risks. Installing filters or separators to remove contaminants is another effective strategy.

Corrosion Prevention

Protective Coatings and Materials

Corrosion can severely damage heat exchangers. I’ve found that using protective coatings and materials is one of the best ways to prevent it. For example:

Material/Coating	Description
Corrosion-resistant alloy	Isolates the substrate from the environment to prevent corrosion.
IGS HVTS® coating	Upgrades internal metal alloy without creating heat-affected zones.

These coatings act as barriers, shielding the base material from chemicals, high temperatures, and abrasion.

Optimizing Operating Conditions

Maintaining optimal operating conditions is another way to reduce corrosion. I always monitor flow rates to ensure effective heat transfer. Avoiding extreme temperatures or pressures also helps. Control systems can stabilize conditions, preventing unnecessary wear and tear.
