It is believed that anaerobic bacteria in the coolant liquid are inactivated by oxygen nanobubbles.
In workplaces that use coolant, the occurrence of factory-specific odors has become an increasing problem. Especially in recent times, as concerns about factory tours and evaluations from nearby residents grow, and as there is a greater demand for improving the work environment for employees, the generation of odors has become one of the environmental factors that cannot be ignored. In particular, during the hot summer months, the occurrence of odors becomes more intense, necessitating countermeasures. However, increasing the frequency of coolant replacement or installing air conditioning are also financially challenging measures. The cause of odor generation in coolant is the proliferation of anaerobic bacteria in the coolant, and as it changes from oil-based to water-soluble, it inevitably becomes more prone to decay. *For more detailed information, please refer to the PDF document.

Company information
Our company has developed various devices that utilize microbubbles and nanobubbles (also known as fine bubbles and ultrafine bubbles), including showerheads and micro/nanobubble generators for washing machines that help reduce odors in clothing and remove dirt from behind the drum. Through a joint project involving four organizations, including the Tama Branch of the Tokyo Metropolitan Small and Medium Enterprise Support Center, Professor Ninomiya of the Nippon Institute of Technology, and our company, it has been confirmed that these bubbles are effective in reducing odors in grinding fluids, maintaining emulsion stability, improving workpiece precision, and extending tool life. Additionally, our micro/nanobubble generator adopts a cavitation method that generates bubbles using the air already contained in tap water. This helps prevent rust in the equipment, making it ideal for use with grinding and cutting fluids. Furthermore, the system can be adapted for use as an inline static mixer by incorporating gases such as nitrogen or carbon dioxide.
