Hydrozone
Hydrozone Co., Ltd: Thai water treatment specialist and complementary collaboration partner of Synergy Services for industrial plants.

Hydrozone Co., Ltd is a Thai water treatment specialist founded in 1999, certified to ISO 9001:2015 and with more than 60 projects delivered. It is a complementary collaboration partner of Synergy Services: we keep industrial cooling towers running while Hydrozone designs, builds and commissions the water treatment systems that feed them — two specialists working the same plants from different sides.
