  • The BCP™ 5000 Series Chemistry Removes and Controls Sulfur Deposit in Geothermal Cooling Towers

    In a system with elemental sulfur deposits, DTEA II™ attacks the deposits, causing disaggregation and release of the deposits from system surfaces. Routine dosing of BCP™ 5000 products results in an effective sulfur control program.

AMSA, Inc. is a specialty chemical manufacturer producing products for industrial cooling water treatment programs.

AMSA chemistry is a leading biodispersant used in biofilm control programs. Liquid products are used in slug (clean-up), semi-continuous (maintenance), or continuous modes (maintenance) in both small and large sized water cooling/process water systems. AMSA also specializes in solid slow release tablets which last about one month in small cooling tower applications. AMSA chemistry can be used in traditional scale & corrosion all-one-drum formulas.

How our Products work

Do your water treatment programs contain a biodisperant to maximize bioilm control?

  • Are the surfaces in your cooling water systems free of organic deposits?
  • Do your water treatment programs deliver maximum cooling efficiency?
  • Do your cooling tower chemical programs protect your metal surfaces from microbial influenced corrosion (MIC)?
  • Do you have good microbial control in your cooling water systems?

If you answered "yes" to any of these questions, you may consider using AMSA BCP™ chemistry.

Customer Testimonials

  • DTEA II™ has become a cornerstone of cooling tower biofouling control.

    As a biodispersant, DTEA II™ has helped us to maintain excellent control of algae, fungus, and bacteria, especially when paired with a microbiocide.

    The DTEA II™ SR Plus SC tablets have been an excellent solution for control of organic and corrosion issues in small to medium towers. The ability to add a single tablet to a small basin once a month has meant a reduction in maintenance concerns and time spent treating small and medium towers.

    -Jerry L. Meyer Jr. CWT

  • The DTEA II™  solid slow release tablets are an ideal ‘do it yourself’ water treatment program for keeping small cooling towers clean.  The tablets are especially convenient for comfort cooling towers located on a rooftop.
