QUOTE START:
No they are not designed to "remove snow". They are intended to prevent the liquid which IS used to remove the snow from refreezing.
You can do the process without T1 fluids, just using hot water, if the OAT is high enough that the risk of refreezing is controlled.
The contaminant is removed through the heat and high pressure of the applied fluid, not it's freezing point depressant properties. The HOT in heavy snowfall is virtually nonexistent, because the fluid rapidly dilutes to the point of uselessness. The same would apply if you apply the snow first then the Type I, unless you used huge amounts of the stuff.

Please read my comemnt clearly: What you mean is that the glycol protects the used fluid against refreezing. The main purpose of T1 Fluids is to remove contamination, including snow. as they are not thickened fluids they provide onyl marginal hold-over-time and therefore deicing is main task.
Heat and pressure are the important factors, I am not writing that glycol deices the aircraft.
And by the way: Read the hold-over-time tables. For heavy snowfall no hold-over-time at all and not onyl virtually none.
I suggest to attend the next SAE G12 Meeting in Frisco and make a statement that "T1 fluid are not designed for snow removal". You will have a lot of smiles at least on your side.
