HG ST PRO

PEM Hydrogen generator

Intro Features and applications Technical specifications

The HydroGen series HG ST PRO is able to generate up to 600 cc/min Hydrogen with purity better than 99.99999% and pressure up to 16 bar (232 PSI).
The HG 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 HG ST PRO is the ideal Hydrogen for all GC-FID detectors. The on-board CPU constantly control 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
