Nitrogen engine.

Also to inflate pneumatic tyres.

It must be very, very expensive. A doctor at a medical centre wanted to charge me $90 for a 2 or 3 second burst of it to freeze a little something off the back of my hand.

I had to laugh, and then told him what it costs per litre. then went elsewhere and they did it for free.

You don't have to heat it to turn it into a gas. Nitrogen is used to remove condensation Aircraft magnetos in the Tropics. Nev

I think the idea is you want it to be quite high pressure, and lots of it, so heat is in the mix there. Possibly running through a 'radiator', which in this case is absorbing heat from the air.

No IT has to be dry and get rid of condensed moisture inside the Magneto by Absorbtion and evaporation. Nev

What is this a reply to?

I previously spent a lot of time rebuilding and tuning Motorcycle and mountain bike suspension, I used bottled Nitrogen to recharge units that used the gas instead of a coil spring.

Mainly used as its inert so wont encourage internal corrosion

Air is about 3/4 Nitrogen anyway, but its the oxygen that causes strife.

I've always thought that Oxygen is some sort of dark joke from the big guy, we need it to stay alive but its slowly killing us🤪

When I first posted this thread, I never imagined that it would stir the thought pot so much, but the response has been really interesting from all.
