HG Pro

PEM Hydrogen Generator

The HydroGen series HG PRO is able to generate up to 1500 cc/min of Hydrogen with purity better than 99.99999% and pressure up to 16 bar (232 psi). The HG PRO includes a new long life multilayer electrolytic cell with polymeric membrane (PEM) using distilled water. No acid or alkaline solutions are used. The innovative gas drying system (two-column drying PSA system with automatic regeneration) ensures the maximum grade of hydrogen purity, it is completely maintenance-free and allows continuous operation, 24 hours a day. The on-board CPU automatically check for internal leaks and constantly control the operating parameters to guarantee full safety. Up to 20 units can be connected in parallel using an external control box. The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit. Stackable with various other models: AG-OFCAS35; NG-EOLO; AG-ZA-Fid
