Yamaha Fine Technologies Offers Industry-first System to Safely Generate Blended Hydrogen/Nitrogen Gas
HAMAMATSU, Japan, Feb. 21, 2020 /Kyodo JBN-AsiaNet/ --

- Ready to Take Orders for YMHN-50 Hydrogen Trace Gas Generator -

On March 2 (Monday), Yamaha Fine Technologies Co., Ltd., a subsidiary of Yamaha 
Corporation, will start taking orders for the YMHN-50, a system for automatic 
generation of the non-flammable hydrogen-nitrogen gas blend that is used as 
trace gas for leak testing of airtight products.


The YMHN-50 can generate a hydrogen-nitrogen gas blend (below, "hydrogen trace 
gas") from just an injection of purified water, and is also capable of 
generating hydrogen trace gas easily and economically.
*Trace gas: Very small quantities of a gas that, in product airtightness 
investigations and testing, is mainly used to detect leakages in test subjects.

- Generates hydrogen from purified water and extracts nitrogen from air, then 
  blends them precisely to produce hydrogen trace gas.
- Highly reliable safety system emits no flammable hydrogen gas.
- Under Japanese law, no legal applications need to be submitted for 
  installation and the system can be installed smoothly into a production line.
