What is different from buying direct
Every item on this page can be bought from the manufacturer directly. Buy direct and these three are yours to handle.
You get the whole set
Buying an electrolyser does not mean hydrogen comes out of it. A stack on its own does nothing. It needs a unit that cleans the feed water, a pump that circulates the electrolyte, an instrument that checks the gas coming out, and a dryer that takes the moisture off. Quotations from different suppliers cover different parts of that, so they are hard to compare.
Tell us what you are running and we will put together the configuration you need. If your lab already has the instruments, we leave those out and fill in the rest.
You buy only what you need
It is easy to pick a power supply sized for a whole stack when you are running a single cell, because in a catalogue the larger one looks like the safer choice. Water is the same. If the site uses a few litres a day, a unit that treats hundreds of litres an hour costs several times more and only adds things to maintain.
We check the products you have chosen against the conditions we run. We will review quotations you have received elsewhere as well. If a specification is more than you need, we say so first.
You know what has been verified
Catalogue performance is measured under conditions the manufacturer sets. A small difference in temperature or electrolyte and the same figure does not come back. What those conditions were, and whether anything else was tried, is often not written down.
For conditions we have run ourselves, we answer with measured data. For conditions we have not run, we say plainly that they are unverified, offer the item as a candidate only, and confirm it together with you.
Warranty and lead time differ by item. Both are on the part pages.
