The secret behind the DCW solution is hypochlorous acid (HOCl), produced by electrolysis using water, salt and electricity. Hypochlorous acid is the active ingredient in the disinfectant NEUTHOX, which the DCW generators dose into, among other things, the cooling water in an ultra-low and very precise concentration. NEUTHOX effectively destroys bacteria, and at the same time it is safe for humans and the environment.
“We no longer have bacteria and other build-up circulating in the pipes, and this saves us on repairs and maintenance on our cooling towers. It also reduces electricity consumption, as the cooling water pumps can get the water around more easily. All we have to do now is to refill the generators with salt and check them twice a year. Otherwise, they run efficiently and stably. The constant uptime is crucial to us,” says Martin Brander.
Martin Brander also emphasizes that the solution provides a safer working environment: “We no longer have to deal with chemicals in the cooling towers, and at the same time there is no risk of spreading Legionella bacteria in the air, because the cooling water is completely clean. Legionella can otherwise grow in the biofilm in vessels and pipes and atomize itself to the surroundings when the cooling water evaporates,” he says.
