Our History

History

Cool Water Technologies is part of the Rosenwach family of companies. Founded in 1866, Rosenwach has over 150 years of experience providing innovative and cost-effective products and services. The core company, Rosenwach Tank, manufactures, installs, and maintains water tanks. In the 1960s, cooling towers used wooden wet decks made from redwood. Since Rosenwach had one of the largest sources of redwood east of the Mississippi, the company made the natural transition to renovating cooling towers to meet the growing demand for air conditioning.
