H2ZA 65 RC
LEMAN Instruments designed the H2ZA 65 RC product line of High Purity Hydrogen & Zero Air Generator with compressor to supply independently all gases necessary to FID detector, close to the consumer in an elegant casing with full color display and touchpad.
The H2ZA 65 RC comprises a Hydrogen generator, an ultra-zero air generator, and an air compressor.
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. It is available 24/7 with a constant purity >99.99995%. Output pressure is regulated electronically and could be set from 0.5 to 5 bar. This process can be started on demand and does not require any caustic solution.
Based on the Pressure Swing Adsorption (PSA) technology, compressed air is dried and filtered from pollutant gases and then passes through a hot catalytic chamber to remove HC, CO, and CH4. Output pressure is regulated from 0.5 to 5 bar.
Each instrument has high-performance communication interfaces USB, RS485, Ethernet, and WLAN (opt) to create a flexible gas network with local or central control.
The software’s focus on safety, automatic regulation, and reliable communications makes the H2ZA 65 RC easy to install, reliable, safe, and pleasant to operate.
