I have just seen an add for a new R407F which is supposed to be equiv to r22 but slightly better at low temps. I haven't seen anything in writing...has anyone?

Have read in one of the trade mags that its been tried in a few supermarket systems and worked well.
Thinking about giving it a try in some milk cooling systems as a few have low and high temp evaps on same units, so would need a low temp drop in to run the icebank and then a high temp one to run the tank, this sounds like it will cover both.

Hi friends ,
Can R407F can be used in systems which were earlier designed for R22(which are presently in operation with R22) ?
Thanks for your cooperation.
