i use this film, it is the same thing as kodak " SO-132 " single step duplicating film .

it is simple to use, with a 300W flood light ... it's for contact printing
( the same speed as a silver chloride emulsion ( like azo ) )

durst makes ( or used to make ) an enlarger lamp / enlarger that can do this
( the one that can be used to enlarge negatives on pt/pd + azo )

but i don't imagine it would be cost effective just to enlarge a few negatives ...

good luck !
