Description

Honeywell R-404A is a widely used HFC refrigerant gas commonly used in refrigeration systems. It is
particularly popular in commercial and industrial refrigeration, especially for systems requiring low- and
medium-temperature cooling, such as supermarkets, food storage, and transportation. Below is a comprehensive
description of Honeywell R-404A refrigerant gas, specifically focusing on its best attributes and characteristics.
Ozone Depletion Potential (ODP): 0 (Non-ozone-depleting, making it an environmentally safer choice compared to
older refrigerants like R-12 and R-22) Global Warming Potential (GWP): 3,943 (R-404A has a relatively high GWP, which
is a concern for its long-term environmental impact, leading to the introduction of lower-GWP alternatives like R-448A and R-449A)
