AOP technology that improves the "thermal conductivity reduction" and "cleaning costs" of heat exchangers.

Kitz held the "1st Kitz Water Sprinkling Event" on August 7, 2026, at the Chino Factory in Chino City, Nagano Prefecture, in conjunction with Water Day (August 1) and Water Week (August 1-7). The Kitz Group has supported the water infrastructure of society, including water supply and sewage systems, with its core valve business. This event, held in line with Water Day and Water Week, was designed as an opportunity for each employee to learn the importance of water, raise awareness about the effective use of water resources and environmental conservation, and reaffirm the value and role that Kitz provides to society. Before the water sprinkling, the surface temperature had risen to about 52°C, but it was confirmed to have decreased by about 15°C after the event, allowing participating employees to once again experience the cooling effect of water and the importance of effective water resource utilization. ■ Water purified with Pure Cleanser was used For this water sprinkling, reclaimed water purified from groundwater within the factory using our water treatment device "Pure Cleanser" was utilized. By employing advanced oxidation processes (AOP) using ozone, ultraviolet light, and photocatalysts to remove color and odor, we are achieving both effective use of water resources and reduction of environmental impact.

Recently, our company was featured in the news media "Pioneers of the Era / Locality!" The article highlights Kitz's journey, the strengths of our business, our corporate philosophy, and our efforts in fluid control technology that supports social infrastructure. It introduces the history of how Kitz has grown while supporting social infrastructure and industrial foundations, as well as our challenges toward a sustainable future.
