Product details
R-507 is the azeotrope that sits alongside R-404A in commercial refrigeration, and it is a common charge in low-temperature freezer work. Being an azeotropic blend, it behaves close to a single compound in service: effectively no temperature glide, which makes superheat and subcooling readings straightforward.
This is a 25 lb cylinder for service and replacement work on equipment already running R-507. It is not a drop-in for other gases — match it to what the data plate or the last service sticker says is in the system.
Highlights
- 25 lb cylinder
- Azeotropic blend — effectively no temperature glide
