UFB DUAL® 50A Main Unit

Transforming Water Throughout the Entire Facility into Cleaning Water Using Japan’s Most Cutting-Edge Technology

UFB DUAL® is an innovative ultra-fine bubble generator nozzle that utilizes Japan’s advanced patented technology and is installed directly on the main water valve.
Unlike conventional localized equipment, it transforms all water throughout the building into water with high cleaning and antifouling effects. Targeting hotels, factories, and large condominiums overseas, it solves serious infrastructure issues such as biofilm (slime) buildup within water supply and drainage pipes and aging pipes.
Its unique structure limits reductions in water pressure and flow rate to 5% or less, providing the world with overwhelming business value through maintenance-free operation, extended equipment lifespan, reduced detergent use (contributing to the SDGs), and cost reduction.

Water Pipes with Scale and Grime Buildup

The Worsening Problem of Aging Pipes and the Significant Cost Burden of Cleaning and Maintenance

In large facilities such as hotels, factories, and condominiums overseas, the buildup of biofilm (slime) and scale inside water supply and drainage pipes due to water quality has become an extremely serious issue. If left unaddressed, this leads to not only reduced water flow and foul odors but also malfunctions in expensive equipment and unexpected downtime. To prevent these issues, facilities perform regular high-pressure washing and pipe cleaning using large quantities of chemicals. However, the enormous maintenance costs put pressure on facility operating profits. Additionally, the heavy use of potent chemicals places a significant burden on the environment from an SDGs perspective, making a sustainable solution an urgent priority.

UFB DUAL® Structure

Physically Removes Grime Using the Electrical Properties and Penetrating Power of Foam While Maintaining Water Pressure

UFB DUAL® utilizes a unique, patented structure (cavitation method) to convert air dissolved in water into ultra-fine bubbles—more than 50 million per cubic centimeter—while limiting reductions in water pressure and flow rate to 5% or less of their original levels. These bubbles carry a negative charge, which electrically attracts positively charged grime such as biofilms and urine scale inside the pipes, physically adsorbing and stripping them away. Furthermore, by reducing the surface tension of water, it instantly penetrates even the smallest gaps. Since the bubbles remain suspended in the liquid for several months to a year, they prevent grime from reattaching to previously cleaned areas 24 hours a day, keeping the inside of the pipes clean without need for chemicals.

The Moment Grime Is Removed from Massive Water Distribution Pipes

Removes 35 Years’ Worth of Grime from Massive Water Distribution Pipes Using Only Water

The effectiveness of this issue-solving mechanism has been proven in demanding sites. In an experiment conducted by a Japanese railway company (JR East), urine scale that had been firmly built up in station restroom pipes for 35 years and could not even be cut with a saw was completely removed after approximately 100 hours using only water, without any chemicals. Additionally, it contributes to cleaning RO membranes and extending the service life of unit tubes in Japanese dialysis hospitals and dental clinics, where advanced hygiene management is required. It has been installed in over 10,000 residential homes, commercial facilities, and factories, helping to reduce the use of chemicals and detergents while reducing costs.
