PEM Hydrogen generator with ZeroAir integrated


The HydroGen series HGA ST PRO is able to generate up to 600 cc/min of Hydrogen with purity better than 99.99999% and pressure up to 16 bar (232 psi). An AirGen output can deliver hydrocarbon free pure Air with a flow up to 2000 cc/min. The HGA ST PRO includes an electrolytic cell with polymeric membrane (PEM) using distilled water. The two-column PSA drying system with automatic regeneration ensures the maximum grade of hydrogen purity, and is completely maintenance-free. The HGA ST PRO is the ideal Hydrogen and Air Generator for all GC-FID etectors. The on-board CPU constantly controls the operating parameters to guarantee full safety. The touchscreen LCD interface provides simple and userfriendly management of all functions on the unit.
