How Mexel Works
• Mexel’s treatment method is different
– Protects the internal surfaces with a molecular coating that
prevents the problems and maintains efficient heat transfer
– Solves multiple problems with minimum impact on the
environment – Goal = prevent, not kill in fresh and salt water

Important Extra Benefits
•
Environment
–
–
–
•
Materials compatibility
–
–
•
Readily biodegradable - replaces multiple toxic chemicals
Extensive independent laboratory research has documented superior
performance and safety in normal operating conditions
Numerous NPDES permits already in place.
Tests on all types of materials show no evidence of chemical impact
at recommended treatment levels
Includes metals, alloys, elastomers, plastics and aggregates
Simplified operations
–
–
–
Single emulsion replaces multiple chemicals – biocides + corrosion
inhibitors + anti-scaling agents
Concentrated product and simple injection require small “footprint”
and provides fully automated operations
Safer for workers to handle
