Parker Balston H2PD-300-220 Hydrogen Generator Unit

Module Feature

H2PD-300-220 is Parker Balston H2PD series ultra-high purity hydrogen generator, specially designed for laboratory gas chromatography analysis. It adopts proton exchange membrane electrolysis and palladium alloy membrane purification technology, which can remove oxygen and impurity efficiently.

It outputs stable 300ml/min hydrogen with purity up to 99.99999%. The 220V version is equipped with IEC power connector. It has automatic water replenishment, pressure control and leakage safety interlock functions. It replaces high-pressure hydrogen cylinder, improving operation safety. Widely matched with GC FID flame ionization detector, trace hydrocarbon analyzer and other analytical equipment.

Working principle

Deionized water enters electrolytic cell and is decomposed into hydrogen and oxygen under electric field.

Crude hydrogen flows through palladium purification membrane, only hydrogen molecules can penetrate the membrane to realize deep purification. The built-in pressure sensor stabilizes outlet pressure. Once leakage or overpressure is detected, the system stops hydrogen production and triggers alarm.

Onboard components

PEM electrolytic cell, palladium purification module, pressure regulating valve, liquid level sensor, water storage tank, safety solenoid valve, control mainboard, status display panel.

LED indicators

Front panel LEDs indicate power on, hydrogen generating, pressure normal, low water level and system fault status.

Hardware self‑diagnosis

Self-check covers water shortage, overpressure, internal leakage, electrolyzer abnormality and membrane module failure. Fault alarm and shutdown protection will be activated automatically.

Programming software

Not applicable. Local panel for pressure setting and status viewing.
