HG PRO M (LN)

PEM Hydrogen generator

Intro Features and applications Technical specifications

The HydroGen series HG PRO M can generate up to 20 L/min of Hydrogen with purity better than 99.99999% and pressure up to 16 bar (232 psi). The HG PRO M includes a new long life multilayer electrolytic cell with polymeric membrane (PEM) using ultra pure water. No acid or alkaline solutions are used.
The two-column PSA drying system with automatic regeneration ensures the maximum grade of hydrogen purity. It is completely maintenance-free. The HG PRO M series provides the ideal Hydrogen for many applications, such as CVD, Central Laboratory Supply and other applications in need for reliable supply of UHP. The on-board CPU constantly controls the operating parameters to guarantee full safety. The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.
