There are so many types of Corrosion….

• General or Uniform Corrosion
• Crevice Corrosion
• Stress-Corrosion Cracking
• Galvanic Corrosion
• Pitting Corrosion
• Intergranular Corrosion
• Microbiologically-Influenced Corrosion (MIC)

And the factors and mechanisms differ.

Heat exchangers are susceptible to erosion damage and galvanic corrosion due to contact between the dissimilar metals.  When we leave this damage untreated, the operational efficiency of the system will be seriously undermined with the potential for complete deterioration of components.  If the galvanic corrosion proceeds too long before it is addressed you can get a leak all the way through the tubesheet and the fluid on one side will mingle with the fluid on the other.  This may not be a huge deal if both are water but usually one is refrigerant which might not be very good for the atmosphere or it could be a harmful chemical that should never be leaked.  So, best case scenario is a huge loss of efficiency and capacity in the heat exchanger.  Worst case scenarios include the release of radioactive steam and or catastrophic EPA fines.

Belzona® has the right solution to protect these units.  Our products are electrical insulators and provide outstanding barrier properties so all those types of corrosion I’ve listed above are no longer an issue. Your component equipment is protected for the long term and by that we mean 20, even 30 years and sometimes longer.  

For 2015 we have two automotive manufacturers and four universities specifying Belzona® on their tube sheets and water boxes.  One of the universities is coating seven of their units at the point of manufacture.  Trane now offers Belzona® coatings factory installed.  Coating your component equipment saves on lifecycle maintenance costs.  Belzona® reduces those dramatically.  

Give us a call when you open up your chillers and let us give you a viable, cost effective option to replacement to address the corrosion in your system.

As always, thank you for your continued support and please feel free to call us anytime.
