Key Properties of R-407A
Low Boiling Point
Boils at about -49.9°F (1 atm), making it practical for both medium and low-temperature refrigeration systems.
High Pressure Operation
Operates at higher pressures than R-22, so systems need compatible components to handle the load.
Improved Energy Efficiency
Provides stronger energy performance compared with older refrigerants like R-22.
Zero Ozone Depletion
ODP is 0, meaning it does not damage the ozone layer and is safer for the environment.
Global Warming Potential
Has a GWP of around 2110 — lower than R-404A, though still higher than next-generation blends.
Non-Flammable
Rated A1 by ASHRAE: non-flammable and low toxicity for safe handling.
