The "harsh" realities of pressure on Regs

[Rick Murchison]

Sorry for being ill-informed - but what does this mean in English?

A regulator is like a 200MPH rated tire. Whether you drive it at 55MPH or 80MPH it'll still hold up just fine, thank you. It may wear a little more at 80, but either way it'll far exceed its design service life.
IOW, while there may theoretically be more wear & tear on the consumables inside a reg when using it with high pressure, it isn't enough to make any practical difference in the real world. Regular service intervals apply.

If I understand you correctly, you are implying that the argument for "special" regulator brands/models for 300 bar utilization is not a very valid argument (since the wear and tear isn't enough to make any practical difference in the real world).

Atomic Walrus & DA Aquamaster,

Talk about "adiabatic cooling load" - phase change of breathing mix supply from liquid state to gaseous state is something I hadn't really thought about someone attempting before. Latent heat vs. sensible heat ya know . . . I suppose the great "diaphragm vs. piston" discussion over first stage freeze-up would have a new venue though.
