Are you troubled by the recurrence of algae, slime, and scale in cooling towers, the increase in annual cleaning and chemical costs, and measures against Legionella? Seven Corporation's multifunctional aqueous solution "SEA’S 7" is a preventive maintenance solution that transforms cooling water into a "dirt-resistant environment" simply by being added to the cooling water. SEA’S 7 is made from 100% natural ingredients, destroys slime (biofilm), and suppresses the regrowth of algae and bacteria. It has also been tested to inactivate 99.997% of Legionella bacteria in just 180 seconds. In fact, at S Factory, foam disappeared within two days of implementation, and during the inspection one year later, it was evaluated as "no algae or sludge adhesion," leading to the conclusion that annual cleaning was unnecessary the following year. SEA’S 7, which simultaneously achieves reductions in cleaning costs, electricity, and chemical expenses while ensuring safety and environmental compliance, is also ideal for equipment improvements at the end of the fiscal year.
