Water electrolysis high-purity hydrogen (oxygen) generation device

We are utilizing hydrogen utilities in various production and research fields.

Our company offers a "water electrolysis high-purity hydrogen (oxygen) generation system" that supplies CO2-free hydrogen using renewable energy sources such as solar and wind power through water electrolysis. Since it directly electrolyzes pure water, the contamination of impurities is extremely low, generating high-purity hydrogen gas (oxygen gas). Because it contains no impurities, it is suitable for use as hydrogen in fuel cells. Please feel free to contact us if you have any inquiries. 【Features】 ■ Produces high-purity hydrogen (oxygen) gas ■ Simple operation ■ High safety ■ Customizable to meet needs ■ Containerized design, requiring minimal space *For more details, please download the PDF or feel free to contact us.

PEM hydrogen generation device "HG PRO"

Compact and lovely design. Can be stacked as well.

The "HG PRO" is a PEM hydrogen generation device that can produce ultra-high purity hydrogen with a purity of 99.99999% or higher, at a maximum flow rate of 1500 mL/min and a maximum pressure of 9 bar (130 psi). Using a long-life multi-layer electrolytic cell with a polymer electrolyte membrane (PEM), the hydrogen generated from ion-exchange water through electrolysis is processed through an electronically controlled high-pressure gas-liquid separator (GLS) (patented) and a two-column PSA drying system with automatic regeneration function, resulting in ultra-high purity hydrogen of 99.99999% or higher. 【Features】 ■ Equipped with electronically controlled high-pressure GLS (patented) ■ Standard software for automatic water replenishment to the internal tank ■ Maintenance-free two-column PSA drying system ■ Maintenance requires only the replacement of the deionization filter ■ 2-year warranty (extension of warranty period and maintenance contracts available) *For more details, please download the PDF or feel free to contact us.

PEM hydrogen generation device "HG KUBE V2"

We introduce low-cost products with high purity hydrogen of 99.9996% or higher!

The "HG KUBE V2" is a PEM (Polymer Electrolyte Membrane) hydrogen generation device that produces hydrogen by electrolyzing ion-exchanged water in an electrolysis cell. The generated hydrogen has water vapor removed by a static dryer and a drying agent column before being supplied to the application. If zero air is also required, the integrated hydrogen/zero air "FID Station KUBE/KZA V2" is recommended. 【Features】 ■ High purity hydrogen of 99.9996% or higher at a low price ■ Equipped with electronically controlled high-pressure GLS ■ High-performance humidity prevention guard included ■ Relief valve included ■ Maintenance involves only the replacement of the drying agent and deionization filter ■ System management via LCD touch screen *For more details, please download the PDF or feel free to contact us.

Highest level of hydrogen concentration! Hydrogen generator "aqpia"

Why is it that we continue to be chosen by "people who seek authenticity"?

**Three Reasons to Choose Us** 1. The Only One in Japan! Everything from Development to Manufacturing is Made in Japan Our product is developed, designed, and supported by researchers who have been conducting hydrogen research in university laboratories for many years. Manufacturing takes place in a factory located in Kawasaki City, Kanagawa Prefecture, making it the only "purely made in Japan" product that completes all processes domestically. You can use it with peace of mind for a long time. 2. The First in Japan! Maintenance-Free Typical hydrogen generators require regular replacement of filters and electrode components (electrode rods). However, our product requires no such maintenance at all. You can use it for a long time without worrying about replacement timing or running costs. 3. Highest Level of Hydrogen Purity Recognized by Public Institutions Our product is a hydrogen generator developed and designed by researchers who have been conducting hydrogen research in university laboratories for many years. It generates hydrogen with a purity level of 99.89% through a safe and highly efficient water electrolysis method (PEM type / some parts are patent pending) using proprietary technology. This purity has been officially verified and certified by the Kanagawa Prefectural Institute of Industrial Technology, a public research institution.
