HYDRO70 LS
LEMAN Instruments designed the HYDRO70LS product line of High-Purity Hydrogen Generators to aliment GCs, for research on fuel cells, and to fit almost any type of application that needs H2 production on demand close to the consumer in an elegant casing with a full-color display and touch screen.
Based on the field-proven Solid Polymer Electrolyte (PEM) cell technology, pure Hydrogen is produced at low pressure from electricity and high-quality distilled water. After production, H2 is dried by a passive dryer and then purified and dried by passing through a No Maintenance Smart Pulse PSA module. H2 is available 24/7 with constant purity >99.99999%. Output pressure is regulated electronically and could be set from 0.5 to 7 bar. This process can be started on demand without a caustic solution. The device is composed of several independent modules connected in parallel. In case of failure, each module could be switched off and removed from the device without interrupting the production of other modules.
Models with outflows of 1 and 2 L/min H2 are available.
Each instrument has high-performance communication interfaces (Ethernet) to create a flexible gas network with local or central control.
A cogeneration network can be installed as an option.
Due to the software being focused on safety, automatic regulation, and intuitive and reliable communications, the HYDRO70LS High Flow, Ultra High Purity Hydrogen Generators are easy to install, reliable, and pleasant to operate.
