KALTON REFRIGERANT GAS R-507

Description

• Type: HFC azeotropic blend (must be charged in liquid phase).

• Boiling Point (1 atm): ~ –46.7 °C.

• Critical Temperature: ~ 70.9 °C.

• Critical Pressure: ~ 37.1 bar.

• Ozone Depletion Potential (ODP): 0 (no chlorine, safe for ozone).

• Global Warming Potential (GWP): ~ 3,985 (very high).

• ASHRAE Safety Class: A1 (non-flammable, low toxicity).

Applications

• Designed as a replacement for R-502 in low and medium-temperature refrigeration.

• Widely used in supermarkets, cold storage warehouses, food processing plants, ice machines, refrigerated transport, and other commercial refrigeration systems.

• Performs reliably across a wide range of evaporator temperatures.

Advantages

• No ozone depletion (ODP = 0).

• Excellent performance very close to R-502, making it a strong retrofit option.

• Azeotropic blend: no significant glide, so system operation and maintenance are easier compared to zeotropic blends like R-407C.

• Safe to handle under normal conditions (non-flammable, low toxicity).

Limitations

• Very high GWP (~3985) means it has a strong greenhouse impact.

• Under global regulations (EU F-Gas, Kigali Amendment), R-507 is being phased down in favor of low-GWP alternatives like R-448A, R-449A, R-452A, or natural refrigerants (CO₂, hydrocarbons).

• Requires POE lubricants (not compatible with mineral oils).
