Dear K. Dick and K. Manee

Hope you are doing well.

I cannot thank you enough for providing us with your EST system and that we are among the first users of the new technology – electrocoagulation in our cooling tower. More important is your full support and guidance with high degree of precision and thoroughness to keep the system running in top condition. We sincerely hope other CT owners would be fortunate to have your system as integral part of their chiller-ct water treatment system which will make their system more complete. With your constant hard work, the long term goal of making the greener and cleaner world will be more of a reality.

With best regards

Rangsit Udomphol, Managing Director
