An equipment, with a plate heat exchanger, for testing seawater side fouling was operated for an extended period using seawater as the cooling heat source. The effectiveness of the electromagnetic processing equipment for marine biofouling was examined. The following results were obtained: 1) The overall heat transfer coefficient decreased by 25.7% without electromagnetic processing equipment and 21.7% with electromagnetic processing equipment compared to that at the start of the experiment. 2) The fouling factor 30 days after the start of the experiment was 7.08×10-5 m2 ·K/W without electromagnetic processing equipment and 6.34× 10-5 m2 ·K/W with electromagnetic processing equipment.
