HGA ST Basic

PEM Hydrogen generator with ZeroAir integrated

The HydroGen series HGA ST BASIC is able to generate up to 600 cc/min of Hydrogen with purity better than 99.9999% and pressure up to 10 bar (145 psi). An AirGen output can deliver hydrocarbon free pure Air with a flow up to 2000 cc/min. The HGA ST BASIC includes a new long life multilayer electrolytic cell with polymeric membrane (PEM) using distilled water. No acid or alkaline solutions are used.

The innovative drying system ensures the maximum grade of hydrogen purity, protects the GC thanks to its innovative humidity safe guard, HGA ST BASIC is completely maintenance-free and allows continuous operation, 24 hours a day. The on-board CPU automatically checks for internal leaks and constantly controls the operating parameters to guarantee full safety. Up to 20 units can be connected in parallel mode using an external control box. The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.
