We have updated information about our new business ventures and initiatives.

Our company has developed a system that enables simple and highly accurate measurement of the calorific value of biogas, and we are conducting demonstration experiments for it.

By focusing on the methane gas contained in biogas and measuring its concentration, we can indirectly determine the calorific value. For measuring methane gas concentration, we use an infrared gas sensor that utilizes the infrared absorption wavelength of gas molecules. This allows for rapid and highly accurate measurement of gas concentration even in high concentration areas. It is equipped with a compact and inexpensive pressure reduction and flow rate stabilization system, enabling the extraction of process gas and real-time data acquisition. An example of methane concentration measurement data can be downloaded from the catalog. *For more details, please feel free to contact us. *Please note that we cannot reply to g-mail addresses on our company system.

Are you having trouble with "promoting carbon neutrality," "responding to the revised Energy Conservation Act," or "ESG management" for designated energy management factories?

Are you having trouble with "promoting carbon neutrality," "responding to energy conservation law amendments," or "ESG management"? In response to energy challenges in factories, such as reducing electricity consumption, decreasing fossil fuel use, and expanding the introduction of renewable energy, our company provides support from energy measurement to solutions based on our track record of 82 energy diagnostics (*). Since we can offer a one-stop solution from proposal to construction, we can promote carbon neutrality while keeping costs down. 【CO2 Reduction Benefits When Implemented (Partial)】 <Hotels> ■ CO2 Reduction Amount: 99t/year ■ Area of cedar forest that absorbs CO2 in one year: 11.6ha ■ Amount of wood pellets used: 162t/year (*) Energy diagnostic achievements…CO2 reduction potential diagnostic project (Ministry of the Environment) *For more details, please refer to the PDF document or feel free to contact us.

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.
