西日本高速道路エンジニアリング関西 List of Products and Services

At West Japan Expressway Engineering Kansai Co., Ltd., we have developed a system called "System" to maximize the extraordinary active energy "Vitalization" possessed by tiny bubbles "Bubble." The ultra-fine bubble generation device "BUVITAS" is a device that efficiently and stably generates ultra-fine bubbles in large quantities at low cost, which can be utilized in various fields. There are several generation methods for ultra-fine bubbles, such as "high-speed swirling liquid flow type" and "pressurized dissolution type," but our company uses the "gas-liquid mixing shear method," which can stably generate high concentrations of ultra-fine bubbles. 【Features】 ■ Can be generated with various gases and liquids Gases: Oxygen, carbon dioxide, nitrogen, ozone, etc. Liquids: Water, ultra-pure water ■ Simple and clear operability BUVITAS can be easily installed and operated like a pot ■ Installation lineup tailored to applications Industrial and research BUVITAS with a wide range of applications BUVITT for small-scale cleaning installations Customizable according to conditions *For more details, please download the PDF or contact us.

The NEW lock nut is a high-performance nut that combines four effects: "bite," "wedge," "anti-loosening," and "amplification," along with the excellent workability of a single nut type. Its powerful anti-loosening effect and high work efficiency have been proven in environments requiring high safety, such as highway bridges and tunnels. 【Examples of Achievements】 - Noise barrier installation work - Tunnel lighting equipment installation work - Backside sound-absorbing panel installation work - Tunnel interior panel work - Sign installation work - Mechanical parking lot equipment - Mega solar facility construction - Inspection paths for bridge inspections *For details, please download the catalog and contact us.

【Product Overview】A single-type locking nut used on screws in areas subject to vibration, providing anti-loosening and anti-falling effects. The combination of a recessed nut and an eccentric washer exhibits a powerful anti-loosening effect due to the wedging action, even in vibration environments where double nuts would loosen. Temporary tightening can be done by hand. Torque management is required only once.
