For what its worth, R13 was (and may still be ) used in vapor traps for
vacume systems typicaly found in laboratories (freeze dryers, etc). The idea
being to remove moisture before it gets to the vacume pump-- some cascade
systems got to around -120 C as I recall (I serviced these units about 20
years ago and as I am an old fart, my memory is not too good anymore---I
believe the refrigerant I used was actualy called R13B1)
