Compressors for hydrogen applications
The PPI line of diaphragm compressors (photo) is specifically designed to address the challenges associated with compressing H2 from low pressure levels (such as electrolyzer outlet pressure) up to levels that are required by today’s vehicles that run on H2. PPI compressors feature triple diaphragm sets, which ensure that the process gas is isolated from the hydraulic oil to ensure absolute process purity. Every process-contacting part in a PPI compressor is made from corrosion-resistant alloys, making them ideal for H2 processing, as well as other applications involving hazardous gases. The static seals in PPI compressors ensure zero leakage of process gas to the atmosphere, and PPI’s leak detection system immediately detects diaphragm or seal failure. All PPI compressors meet API 618 standards. — Sundyne, Arvada, Colo.
