HG Mini

PEM Hydrogen Generator

The HG MINI is able to generate up to 300 cc/min of Hydrogen with purity better than 99.999% and pressure up to 12 bar (174 psi). The HG MINI includes a cell with polymeric membrane (PEM) using distilled water. No acid or alkaline solutions are involved.

The innovative static drying system ensures the maximum grade of hydrogen purity, protects the GC thanks to its unique humidity safe guard.

The on-board CPU automatically checks for internal leaks and 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 LED matrix interface provides a simple and immediate display of the status of the unit.
