R-507 (Genetron® AZ-50, SUVA® 507) is an azeotropic HFC blend of R-125 / R-143a (50 / 50 wt %) engineered for medium- and low-temperature commercial refrigeration, replacing R-502 and R-22 in new equipment and many existing R-502 systems.

Key properties
• Zero ODP, GWP 3 985 (IPCC AR5)
• Boiling point –46.7 °C; critical temperature 71 °C
• 5 %–8 % higher capacity than R-502 at same conditions
• Non-toxic, non-flammable (ASHRAE A1/A1)
• Net 25 lb cylinder typical (cylinder + packaging ≈ 32 lb)

Applications
• Supermarket display cases, walk-in/freezer cold rooms, transport refrigeration, ice machines, low-temp process chillers

Regulatory
• SNAP-approved for new and retrofit use; no new HCFC equipment allowed since 2010
• EU F-Gas quota system already restricts virgin R-507; U.S. AIM Act phase-down starts 2025

Environmental outlook
• High-GWP HFC; long-term migration to ultra-low-GWP refrigerants (R-448A, R-449A, CO₂, R-455A) is accelerating

Retrofit notes
• Compatible with POE oil; mineral oil must be flushed
• Requires liquid charging to maintain blend composition; TXV superheat readjustment recommended

The cylinder(s) may come in grey or other colors.
