R-404A 24 Lbs Refrigerant Virgin New Factory Sealed Gas

This 24 lb. cylinder contains factory-sealed, 100% virgin R-404A refrigerant, a zeotropic HFC blend of 44% R-125, 52% R-143a, and 4% R-134a widely used in commercial and industrial refrigeration. Unlike near-azeotropic blends, R-404A gas exhibits a measurable temperature glide, so it must always be charged into a system as a liquid to preserve the correct component ratio and prevent fractionation. Originally developed as a drop-in replacement for R-502 and low-temperature R-22 systems, this non-ozone depleting refrigerant requires POE (Polyolester) lubricant for proper oil return in compressors. Marketed under names such as Genetron 404A, Suva HP62, and Forane 404A, it carries an ASHRAE A1 safety classification, confirming low toxicity and no flame propagation. When performing a refrigerant recharge on supermarket display cases, walk-in freezers, or transport refrigeration units, utilizing virgin R-404A ensures the absence of contaminants or moisture that compromise suction pressure and superheat readings. Ensure all recovery and manifold equipment is rated for the 3.73 MPa critical pressure of this medium- and low-temperature refrigerant.

Key Benefits for Technicians:

• Reliable Low-Temperature Capacity: Formulated for stable performance across medium- and low-temperature commercial refrigeration ranges, including freezers and cold storage.
• System Longevity: Using virgin R-404A 24 lbs cylinders prevents the introduction of moisture or mixed gases often found in low-quality reclaimed batches.
• Non-Ozone Depleting: Contains no chlorine, making it a compliant HFC alternative to legacy R-502 and R-22 refrigeration systems.
• Liquid-Phase Charging Accuracy: Zeotropic composition requires liquid charging, allowing technicians to maintain the precise 44/52/4 blend ratio for consistent capacity.

Common Contractor Questions:

Can R-404A be used to retrofit an existing R-502 or low-temp R-22 system?
Yes, with modifications. R-404A refrigerant was designed as a common retrofit for R-502 and low-temperature R-22 refrigeration equipment, but the compressor oil must be changed to POE oil, and expansion devices may need adjustment for the different pressure and glide characteristics.

Is an EPA certification required for purchase?
Yes. To purchase wholesale R-404A refrigerant, you must provide a valid EPA refrigerant handling certification or a Resale Statement in accordance with federal law. This product is restricted to the Lower 48 states.

Why must R-404A always be removed from the cylinder as a liquid?
Because R-404A is a zeotropic blend with a notable temperature glide, removing it as vapor would cause fractionation, altering the 44% R-125 / 52% R-143a / 4% R-134a ratio and reducing system performance. Liquid-phase transfer keeps the blend intact.
