HG Basic Hydrogen Gas Generator

The HG Basic hydrogen gas generator is capable of generating up to 700 cc/min of hydrogen with purity better than 99.9999% and pressure up to 10 bar (145 psi).

This innovative and hardy hydrogen gas generator has a new, long-life multilayer electrolytic cell with polymeric membrane (PEM) using distilled water.  No acid or alkaline solutions are used.

Low maintenance?  No, it’s NO maintenance!

The HG Basic hydrogen gas generator is completely maintenance-free, and allows for continuous operation, 24 hours a day.  The central processing unit within the system automatically checks for internal leaks and constantly controls the operating parameters to guarantee full safety.

Connect multiple units for higher volume supply

For users requiring greater supply, up to 20 generator units can be connected in parallel mode using an external control box.  The easy-to-use touch-screen LCD interframe provides simple and user-friendly management of all functions.

This is also stackable with various other models: AG-OFCAS35; NG-EOLO; AG-ZA-Fid.
