Hydrogen regulator for the Protium-1000

Development programme — configuration quotations open · qualification units planned 2027 Q2

The Spectronik Protium-1000 (1 kW) specifies a hydrogen inlet of 0.7 bar (10 psig) in its manufacturer datasheet. There is no universal fuel-cell regulator — outlet pressure and flow must be fitted to the stack. This is the MEYER configuration fitted for it:

HDRX-R350-2S-SS-O0.7-F16-FC:P1000
Fitted outlet setpoint0.7 barg — inside the Protium-1000 window, held to ±0.1 bar as standard
Fitted flow16 SLPM (datasheet)
Supply classes350 / 400 / 450 / 500 bar
ConstructionTwo-stage · 316 stainless steel (no hydrogen embrittlement) · Ø 65 mm · ~245 g target · M18×1.5 cylinder connection

Frequently asked questions

What regulator does the Protium-1000 need?
The Protium-1000 specifies a hydrogen inlet of 0.7 bar (10 psig) per its manufacturer datasheet. The fitted MEYER configuration is HDRX-R350-2S-SS-O0.7-F16-FC:P1000: outlet set inside that window and held to ±0.1 bar as standard, flow sized at 16 SLPM (datasheet).
Can I use it with cylinder pressures above 350 bar?
Yes — the same fitted outlet and flow are available in 400, 450 and 500 bar supply classes (HDRX-R400/R450/R500); select the supply class in the configurator.
Is the regulator available now?
The HDRX-R is in its development programme: configuration quotations are open now, and qualification units are planned for 2027 Q2. Your quotation carries your exact configuration.
