We offer customized protection devices for cooling and heating systems. Our devices use ultrasonic technology to prevent algae and bacterial growth on the heat exchanging components, extending the lifetime of your system. 

Perpetual issues, we’ve got the solution

For over a decade, we have conducted extensive research to understand the impacts and behaviors of liquids, with a focus on the root cause of many of our problems: biofilm. By delving into the mysteries of this microorganism, we have been able to craft a product that addresses some of the most pressing issues caused by biofilm.

Some of the most concerning problems that we have addressed include:

Algae growth on grids

High temperatures, light and air exposure, and the presence of biofilm can lead to the proliferation of algae on grids. This not only decreases the lifespan of these water systems, but also increases energy consumption and maintenance requirements.

Legionella development

Open cooling towers and other systems with water at temperatures between 20°C and 50°C are particularly prone to the development of legionella, especially when the water is stagnant or has long residence times. The presence of biofilm only exacerbates this problem, which can lead to serious illness for personnel and the need to report the issue to authorities.

The presence of scale

Scale in heat exchangers can significantly decrease process efficiency, leading to clogged filters and pumps, disrupted machinery, and a reduction in system function. This translates to lost time and money, as well as decreased returns.


At Ultrasonic Group, we understand that every customer has unique needs. That’s why we offer a range of products that have been specifically designed to combat biofilm in cooling towers, heat exchangers, and other water supply systems.

We’re dedicated to providing the best possible experience for our customers. That’s why we offer personalized recommendations for the optimal arrangement and composition of our ultrasonic devices to ensure the best possible results. Our solution is a reliable way to protect all water-related systems.
