We do not understand that medical gas gains any therapeutic value by being drier than necessary. "Necessary" is a dryness low enough to preclude the formation of liquid water under any circumstance likely to occur in the piping. Below that level it wastes money and energy to over-dry the air, and has the therapeutic disadvantage of requiring rehydration before it can be breathed without patient risk. Some standards have set a dew point level which is based on the dew point achieved by a standard off-the-shelf desiccant dryer (-40°), not on a therapeutic benefit to patients. NFPA has taken a more enlightened approach and has simply required "a dew point below frost point" (i.e. <0°C) which seems more clinically appropriate and economically advantageous for most facilities.
In an industry that touches all of our lives, we know our customers expect the highest quality medical gases and equipment, and the most comprehensive service — and that's what we deliver.
