About R-404 Refrigeration Gas

R-404A is a near-azeotropic HFC blend (52% R-143a, 44% R-125, 4% R-134a) used in low/medium temp commercial refrigeration, known for its -46.5C boiling point and high Global Warming Potential (GWP), making it a replacement for older refrigerants like R-502, but it's being phased down due to environmental impact. Key specs include a molecular weight of 97.6 g/mol, 1000 ppm exposure limit, and suitability for supermarket cases and freezers, with cylinders typically orange.

Key Specifications

Composition: 52% R-143a, 44% R-125, 4% R-134a (HFCs).
Appearance: Colorless, faint ethereal odor.
Boiling Point: -46.5C (-51.6F) at 1 atm.
Molecular Weight: 97.6 g/mol.
GWP: High (around 3922, though not in snippets, it's a key factor in its phase-down).
ODP: Zero (Non-ozone depleting).
Safety: ASHRAE A1 (Low toxicity, non-flammable) but vapors heavier than air.
Applications: Supermarket freezers, reach-in coolers, display cases, transport refrigeration.

Important Considerations

Phase-Down: As a high-GWP refrigerant, R-404A is subject to regulations (like F-Gas in EU, AIM Act in US) and is being phased out for lower-GWP alternatives (HFOs/blends).
Retrofitting: Often used as a retrofit for R-502 and R-22 systems in medium/low temp refrigeration
