I bought the 3 foot high cylinder and 22mm bag when I saw it on Tommorrows world the black and white TV Program.

Any CO2cylinder will do, you just need to get the cylinder company to make it pick up from the bottom of the cylinder.

Tim,

You need the correct cylinder with the " syphon tube" going to base of cylinder . this allows the liquid CO2 to discharge first which reaches atmoslphere and the change to a gas that gives you a temperature of minus 3thousand odd degrees or similar!!.

I remember getting a fire extinguisher company to put in a tube to a pick up from the top cylinder.

Just a couple of points;

why do you need a cylinder?

is it because yours has failled its periodic pressure test?

are you wanting a second cylinder as a reserve?

You will probably be able to get a lacal fire exstinguisher company (one with its own CO2 refil facility) to put a syphon in for you.

At a pinch you could turn a ordinary CO2 cylinder upside down, but the valve handle gets very cold.

If you didnt live so far from Preston you could borrow mine ;)

Tim

PS have you used one of these freezers before.
