Any other Quality cylinders worth looking at? Looking for a good guarantee...not too fussed about built in expansion and ideally looking for one that has > 3bar working pressure...OSO used to do 5bar with their series 20 range but not any more...
Why is it so difficult to get proper details about coil input, thermal loss, flow rates at certain pressures etc
