- Operation: 24/7 continuous supply; intelligent control with auto self-check & live status.
- Protections: Over-pressure sensing & alarm; anti-overflow electrolyzer; anti-carryover/anti-return moisture design.
- Gas Cleanup: High-purity purifier module; easy media replacement.
- Water System: Built-in smart refill pump + large reservoir (longer refill cycle).
- Serviceability: Maintenance-free drying; modular power electronics for quick swap.
- Scalability: Remote link for multi-unit parallel operation to increase capacity.
Need a Safer Hydrogen Source for Your Lab?
HG 2000 generates hydrogen by splitting pure water via PEM (proton exchange membrane) electrolysis. Hydrogen forms at the cathode and oxygen at the anode, with a membrane separating gases for safe collection. The result is ≥99.999% high-purity H₂, delivered continuously and without chemical reagents. Our intelligent control system handles auto self-check, live status, our hydrogen generator can remotely operate multiple units in parallel, and maintenance-free drying, giving labs a stable, clean alternative to high-pressure cylinders.

What Is Hydrogen Generator
A factory-integrated, lab-level hydrogen generator can replace bottled hydrogen. It delivers constant, high-purity gas for GC detectors and research workflows. The system combines a robust PEM electrolyser, high-purity purifier, and smart protections (overpressure alarm, anti-backflow / anti carryover) in a compact unit. It also builds in a smart refill pump and a large water reservoir, which can keep your analyses running with fewer interruptions.

Where You Can Use Our Hydrogen Generator
The hydrogen generator is designed for a wide range of laboratory and research applications. It supplies hydrogen to GC-FID and GC-TCD detectors for both routine and high-sensitivity methods, and also supports hydrogenation reactions in R&D and pilot labs. In addition, it provides a clean hydrogen source for material pyrolysis, thermal studies, fuel cell research, and related experiments. These advantages make the HG-2000 an ideal solution for analytical labs seeking a safer, greener, cylinder-free alternative.

By PEM water electrolysis: water splits into hydrogen (cathode) and oxygen (anode); the membrane keeps gases separated for safe collection.
≥99.999% H₂ for analytical applications.
HG-2000 avoids high-pressure cylinder handling and adds over–pressure alarms, anti–backflow/anti–carryover, and an anti–overflow electrolyzer design.
Yes. It’s built for continuous operation. A maintenance–free dryer, smart refill pump, and large reservoir reduce downtime.
Yes. Units can be linked in parallel remotely to match higher demand.
Routine checks are minimal. Media in the purifier is easy to replace; the dryer is maintenance–free.
Typical uses include GC–FID/GC–TCD carrier/fuel gas, hydrogenation, pyrolysis, and fuel–cell R&D.
