Helium is even more expensive than Nitrogen. How about Argon?

We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

I'd guess any noble gas would be expensive.

Hi, This would be a very exciting idea. Nitrogen is an inert gas, so this is why it's used, however Hydrogen mixed with oxygen in normal air is highly explosive, so it would be one of the worst gasses to use in a reflow oven I would think. Remember

As stated above, Hydrogen is EXPLOSIVE, very bad idea. Management might have meant HELIUM, also inert.

Let's not be hasty about the BTU, the Pyramax consums even more N2 than the Paragon that it replaced by something like another 40%! and the Electrovert aint that much better although it's been a while since I looked at them.

Electrovert has hard data on electrical and N2 consumption for the new OmniEXCEL series ovens to compare with preceeding OmniFlo series. Have a look.

Im not an expert at this, but im going to have to agree with blnorman. I wouldn't use Hydrogen, its very explosive. I would look into a considering a new oven to cut back on cost. Yes you will have to put out the money for a new unit, but if it reduc

Maybe here's an opportunity to get a new oven. Electrovert, BTU and Vitronics offer closed-loop N2 control as an option. This, together with other improvements on oven design can reduce N2 consumption by as much as 40%. Not to mention reductions in e
