GSA Introduces a New Standard for Hydrogen Drying — Palladium-catalyst hydrogen dryer delivers higher purity and efficiency for next-generation hydrogen applications —

Posted on November 5th, 2025 | Filed under Press Releases

GSA has unveiled its proprietary hydrogen dryer, engineered with a palladium catalyst system to deliver ultra-high-purity hydrogen. The new unit combines performance, energy efficiency, and sustainability — setting a new benchmark for hydrogen purification across industrial and clean energy sectors.

SEOUL, South Korea, Nov. 5, 2025 /PRNewswire-PRWeb/ — Global Standard Air / Gas (GSA), a leading provider of compressed air and gas treatment systems, has successfully delivered its hydrogen dryer, designed and manufactured with proprietary technology. The system sets a new benchmark for hydrogen purification, combining performance, safety, and sustainability.

“Our hydrogen dryer embodies GSA’s in-house innovation, delivering higher purity, lower energy use, and greater reliability — a true leap forward in hydrogen technology,” said, Technical Development Manager at GSA.

A Key System for High-Purity Hydrogen

The hydrogen dryer is a device that removes moisture and oxygen from hydrogen gas to achieve ultra-high purity.
Developed with GSA’s own engineering, the unit uses a palladium (Pd) catalyst and adsorbent material to trigger a controlled chemical reaction between hydrogen and oxygen, generating water that is then effectively separated and discharged.
In this process, hydrogen gas is preheated to 110–130 °C and fed into the catalyst tower (T10), where the reaction takes place.
The resulting water is cooled in a water-cooled cooler (GC1)and collected in a separator (SP2)before automatic drainage.
The dried hydrogen then passes through dual adsorption towers (AD1, AD2), where any remaining moisture is fully removed before output.

Continuous Dual-Tower Operation for Maximum Efficiency

GSA’s hydrogen dryer features a dual-tower configuration that allows simultaneous drying and regeneration.
While one adsorption tower (AD1) dries the hydrogen, the other (AD2) undergoes regeneration — consisting of a heating stage to desorb moisture and a cooling stage to stabilize the adsorbent afterward.
A portion of the supply hydrogen is used as a heating medium during regeneration, enhancing energy efficiency.
Once regeneration is complete, the two towers automatically switch roles under PLC-based sequential control, enabling uninterrupted 24-hour operation.
This automation ensures consistent gas quality, lower maintenance requirements, and improved system reliability.

Stability, Efficiency, and Sustainability

The newly developed hydrogen dryer demonstrates exceptional stability under high-pressure and high-temperature environments.
Its integrated level sensors and automatic drainage system maintain precise moisture control without operator intervention.
The regeneration circuit incorporates thermal recovery optimization, reducing energy consumption, while the equipment’s aluminum–stainless hybrid structure provides superior corrosion resistance and extended service life.

Supporting the Growth of the Hydrogen Industry

As the hydrogen economy expands, GSA continues to strengthen its position as a trusted technology partner in gas purification.
The hydrogen dryer will be applied in hydrogen refueling stations, fuel cell power plants, semiconductor manufacturing, and chemical processing facilities—industries that demand ultra-pure hydrogen for optimal performance.

“This hydrogen dryer represents GSA’s proprietary innovation and full in-house engineering capability,” said Technical Development Manager at GSA.
“We will continue advancing technologies that enhance efficiency and safety across the entire hydrogen value chain.”
