KALTON REFRIGERANT GAS R-404a

Description

• Type: Near-azeotropic HFC blend (must always be charged in liquid form to maintain composition balance).

• Boiling Point: ~ –46.2 °C at 1 atm.

• Critical Temperature: ~ 72 °C.

• Critical Pressure: ~ 37.3 bar.

• Glide: Very small (~0.5 K), so it behaves almost like an azeotrope.

• Ozone Depletion Potential (ODP): Zero (does not harm the ozone layer).

• Global Warming Potential (GWP): ~ 3,922 (very high).

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

Applications

• Widely used in commercial refrigeration systems such as supermarkets, cold storage warehouses, ice machines, and refrigerated transport.

• Standard choice for low and medium temperature equipment, including display cabinets, freezers, and food processing refrigeration.

• Compatible with many refrigeration oils, but systems typically require polyol ester (POE) lubricants instead of older mineral oils.
