Mexel is a completely different way of looking at the treatment of systems that utilize water for heating and cooling applications. Unlike traditional water treatment programs that treat the water itself, Mexel is a surface treatment that protects the system from the water. By forming a protective barrier, utilizing Mexel’s film forming amine technology, we are able to prevent scale and corrosion all with one product.
Mexel Surface Treatment Programs address the following:
- Corrosion
- Scale
- Fouling
- Environmental Concerns
- Chemical usage reduction
- Operator Handling
- Operator Management Time
- System Cleaning
- A Green Chemistry Program
