The ESH5 and ESH7 hydrogen compressors are engineered for research and development environments where reliability and intermittent operation are key. These single-cylinder, horizontal, oil-free reciprocating compressors are designed with a small footprint, making them perfect for R&D test facilities or pilot installations. They can be configured with up to two stages of compression and are well-suited for a range of flow rates, making them as reliable and efficient as larger compressors while being compact and easier to integrate into various settings.
