Gas pump for green hydrogen electrolysis process

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)

Contec Co., Ltd. has started selling the "SH-9210TSN," an industrial managed switching hub that has obtained CC-Link IE TSN recommended network wiring component certification Class B. It features dual power supply redundancy, a DC power input, eight gigabit ports, and two SFP slots. The SH-9210TSN complies with IEEE 802.3ab (1000BASE-T), IEEE 802.3u (100BASE-TX), and IEEE 802.3 (10BASE-T) standards, and is designed for use in environments where quiet operation and long lifespan are required due to its fanless design. Additionally, it achieves an operating temperature range of -10 to 65°C thanks to its excellent heat dissipation metal casing. It can be installed on a 35mm DIN rail or mounted on walls using various mounting brackets. In addition to a wide-range DC power input (12-48VDC), it supports input from two power supply lines and includes various managed functions for network management, control, and reliability enhancement.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
