[Featured Article] Featured in the heat exchanger special starting November 28 / Sakai River Industrial Co., Ltd.

Improved heat transfer efficiency with a unique fin shape. Also pursuing compactness and low cost. Available for cold climate specifications.

The "stainless steel fin-tube heat exchanger" excels in corrosion resistance, heat resistance, and strength, ensuring a long lifespan and easy maintenance. Additionally, through collaboration between industry and academia, we have successfully improved the adhesion of the fins, enhancing performance. There are cases where the introduction of this heat exchanger has resolved issues related to corrosion of copper and steel pipes due to water quality impacts, as well as lifespan problems in corrosive environments. It is also suitable for clean usage environments. 【Specifications】 ■ Functions: Dehumidification, solvent recovery, corrosion prevention against corrosive gases and water quality ■ Heat media: Flash steam, saturated water, pure water, well water, industrial water, etc. ■ Element materials - Tubes: Stainless steel pipes (SUS304, SUS316, SUS316L) - Fins: Stainless steel fins (SUS304, SUS316, SUS316L) Other materials available upon consultation Sakaigawa Industries Co., Ltd.'s "rapid filling hydrogen storage alloy tank" has been selected for the "Kansai Manufacturing New Selection 2025" by the Kinki Bureau of Economy, Trade and Industry in the Carbon Neutral Society Realization (GX) category. *You can view a catalog introducing our heat exchangers by downloading the PDF.

• Heating device

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

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.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four ways: left, center, right, with 4 spots and 12 spots settings. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor modes with a single model. 【Recommended for such places!】 ☑ Entrances facing busy corridors ☑ Counters or signs near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.
