The OWELD company's "Hydrogen Burner Brazing Device" is a hydrogen burner that boasts output comparable to that of a gas burner. By not using combustible gases such as acetylene, it achieves zero CO2 emissions and significantly reduces the running costs (gas fees) that were incurred each time it was used. Additionally, it can be installed in a space-saving manner as it eliminates the need for cumbersome gas cylinder exchanges or the installation of supply piping from outdoor supply tanks. Hydrogen and oxygen are generated on demand, so there is no need to store them in tanks, allowing for safe usage. 【Features】 ■ Contributes to CO2 reduction and carbon neutrality ■ Lower running costs compared to conventional gas burners ■ Higher safety due to not storing gas in tanks ■ Provides a constant and stable flame of hydrogen and oxygen *For more details, please refer to the PDF document or feel free to contact us.

In recent years, improving fuel efficiency and reducing exhaust emissions have become important issues for automobiles in addressing global warming and improving air quality. Additionally, household appliances like gas water heaters are designed to use heat efficiently. In such contexts, stainless steel heat exchangers are utilized. Stainless steel has excellent high-temperature corrosion resistance and is widely used in automotive secondary heat exchangers and exhaust heat recovery units for water heaters. Exhaust gases are at high temperatures, reaching 700 to 800 degrees Celsius during full-load operation in vehicles, and gas water heaters generate strongly acidic drain water due to their structure. ◆◆◆ If you are having trouble with brazing, please consult Shinwa! ◆◆◆ The best option for brazing stainless steel heat exchangers is "nickel brazing," which has excellent high-temperature corrosion resistance. Shinwa manufactures nickel brazing paste and sells powders and foil brazing materials. Since we have a vacuum furnace in-house, we can offer "brazing material proposals" and "prototype processing" tailored to our customers' products.
