Benefits
Complete Purification System in One Unit
The integrated system includes a pre-filter, a De-Oxo catalytic unit and a desiccant dryer, which efficiently removes solid particles, liquids, oxygen and moisture.
No Hydrogen Losses During Regeneration
Regeneration uses a partial hydrogen flow that is returned to the main flow after treatment, which means 100 % gas utilisation without losses.
Compact and Modular Design
Short process cycles allow a compact design on a steel skid, which simplifies integration into existing systems and saves space.
Highly Efficient UltraPleat™ Filtration
Pre-filters and after-filters with advanced filtration technology efficiently remove oil and water aerosols as well as solid particles.
Reliable Industrial Design
Construction from high-quality stainless or carbon steel and regeneration under pressure reduce mechanical loads and increase service life.
ATEX Compliance
The system is suitable for use in potentially explosive atmospheres (ATEX zone 2) and meets the requirements for safe operation.
