H2 Generator Desk
ND series

Categories: ,

The ND series generators use an electrolytic cell with polymeric membrane (PEM) to produce pure hydrogen.

The exclusive, electronically-controlled gas/liquid separator, automatic checking for internal leaks whenever starting the unit, and constant control of operating parameters, guarantee maximum safety.

Up to 20 units can be connected in parallel. The touch-screen LCD interface provides simple and user-friendly management of all functions on the unit.

Hydrogen is produced from distilled water using a polymeric membrane (PEM). No acid or alkaline solutions are used.

The ND series features a desiccant cartridge that needs to be replaced or refilled when saturated.
