Condenser for HFC or HC refrigerants

Hello guys,
I've just purchased this condenser for my project, intending to use it for R290 which is a class A3 HC refrigerant. Maybe I've ordered wrong, but the supplier provided me with a condenser for HFC as it's written on its label.
I reckon that condensers for flamable and explosive gasses should have a sealed motor fan to reduce chances of injuries, and this one has not, but other than that, what are the differences among a HFC and HC condenser? The pressure for R290 should even be lower, so I don't think I should be worried about that. Any other things to be wary about? Thanks!
