Nel Hydrogen S-Series Hydrogen Generator

Nel Hydrogen offers the S Series hydrogen generation systems that are capable of producing up to 1.05Nm3/hr (40scf/hr) of ultra-high purity hydrogen gas for a wide range of applications. The compact units are helping numerous industries to avoid costs related to delivery and use of hydrogen.

The S Series hydrogen generators are available in three models: S20 and S40. With a production rate of 20 or 40scf/hr, the systems can generate the equivalent of four cylinders of better-than-UHP grade hydrogen on a daily basis. Nel Hydrogen  also offers the S Series units in high pressure version.
