Method for recovering noble gases using a diaphragm pump.

Process pumps for research and development related to decarbonization and new energy, for the transfer, recovery, and circulation of CO2, hydrogen, oxygen, helium, and others.

In a decarbonized society and the development of new energy, there are many technical challenges that conventional gas pumps cannot adequately address. We believe that the KNF process pump, with its features listed below, can assist in solving our customers' technical challenges. Main features of the KNF process pump: - Contamination-free - A wide range of gas contact materials - Pressure-specific design with a maximum allowable discharge pressure of 1.2 MPa - Vacuum-specific design - Leak-tight design - Long lifespan design - Explosion-proof specifications (optional IECEx / ATEX) - Heat-resistant specifications with gas temperatures up to 240°C (optional) - Weather-resistant coating (optional)

In civil engineering sites, the use of sheet piling methods is essential for safely utilizing the site, including temporary roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates have been widely used, but due to their weight, they can be cumbersome to transport, install, and remove. Hyper CLT sheet piles are civil engineering materials made from wooden CLT for civil use. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to handle with small machinery, contributing to reduced burdens during installation and improved work efficiency. They can be utilized in a wide range of civil engineering sites for measures against muddy conditions, ground protection, heavy machinery scaffolding, and ensuring pedestrian pathways. As a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism NETIS "TH-250021-A," it is also recommended as a material for innovative ideas, safety measures, and environmental considerations in public works.

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!
