Customer Testimonials

  • 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.

  • 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.
