  • As peak cooling demand approaches with rising summer temperatures, maintaining optimal heat transfer efficiency in your cooling towers becomes mission-critical. Even microscopically thin biofilm formations (as little as 1 micron) can dramatically impair thermal performance - reducing heat transfer by up to 29.5% of copper tubes and 2.8% of carbon steel surfaces. G-C's integrated approach combines advanced oxidizing biocides with our Formula 9020 organic dispersant technology to penetrate and disrupt biofilm matrices, enabling superior microbial control while preventing the need for aggressive shock treatments that risk system damage.
