Power and feedwater
200–240 V AC single phase · Type II feedwater
Who it is for
A complete 2 kW system that produces hydrogen on site
HXB-V1 is the 2 kW electrolyzer as a complete system; if you only need the 2 kW stack for your own BoP, that is the HXS-2. Installation feasibility depends on power, water, ventilation, outlet piping and the boundary to purification, drying, compression and storage.
Choose this product when
- Sites using modest volumes of hydrogen continuously where delivery logistics are a burden
- Demonstration or research projects that use remote access to the computer running the desktop app for off-site monitoring and control
- Configurations that connect downstream to drying, storage and compression
SITE CONNECTION
What HXB-V1 covers and what the site provides
HXB-V1 integrates the core functions needed to produce hydrogen. Storage, compression and end-use equipment are configured separately for the site.
HXB-V1
Integrated stack, power, circulation, controls and safety
Hydrogen drying
Not standard · modular product in development
Storage, compression and use
Downstream equipment for the site application
Included supply scope
- Integrated 2 kW stack, power supply, electrolyte circulation, temperature control, automatic water refill and safety logic
- Desktop control app and an MQTT over Ethernet (JSON) interface
- Dryer not included as standard · modular dryer in development · partner product can be recommended when needed immediately
- Dimensional data and an exterior/enclosure-only STEP model available for installation planning
Customer preparation
- 200–240 V AC single phase 50/60 Hz (total consumption approx. 2.4 kW)

Support, lead time and commercial terms3 items
Support & warranty
One-year warranty under standard operating conditions. Routine checks cover feedwater, leaks and operating data; KOH is replaced by condition rather than on a fixed interval. A returned stack can be refurbished by replacing only the MEA and reusing the hardware.
Lead time & status
Available · 8 weeks from PO acceptance
Commercial terms & origin
EXW basis; DAP and other terms by agreement. Country of origin is the Republic of Korea, with certificate of origin provided.
Pricing depends on quantity and Incoterms, so it is issued as a quotation. Before asking for one, compare five years of buying cylinders against making the same hydrogen on site.
