- Optimized for Medium-Scale Projects: Designed to maximize flow and performance in electrolyser projects within the 5 to 20 MW range.
- Reduced Maintenance and Energy Costs: Engineered to minimize upkeep and operating expenses, contributing to lower total cost of ownership.
- Flexible Compression Stages: Offer up to five stages of compression to meet the demands of high-pressure hydrogen applications.
- Compact Design: A two-cylinder layout provides a small footprint, ideal for space-constrained installations.
- Compliant with Industry Standards: Built to API standards, meeting ATEX requirements, and available with CE marking where necessary.
- Adaptable to Renewable Power: Tailored to work seamlessly with installations using renewable energy sources.

The PHE7 and PHE9 hydrogen compressors deliver optimal flow and flexible performance, specifically addressing the needs of medium-scale electrolyser projects ranging from 5 to 20 MW. Distinguished by strokes of 7” and 9” respectively, these compressors are perfect for setups with renewable energy sources or those with variable flow demands. The two-cylinder line design minimizes the footprint and allows for up to five stages of compression, making the series ideally suited for high-pressure ratio applications, such as hydrogen storage and grid injection.
