R-404A Refrigerant 24 lb Jug — Cold Storage, Display Case & Ice Machine Refrigerant
This 24 lb jug of R-404A is the bulk supply for commercial refrigeration contractors. It's used in cold storage cells, supermarket display cases, and ice machines, and as a replacement for R-502 in transport refrigeration. Existing R-502 installations can also be retrofitted with R-404A. It's a blend of pentafluoroethane, 1,1,1-trifluoroethane, and 1,1,1,2-tetrafluoroethane and uses polyol ester (POE) lubricant. For a single small top-off, the R-404A 27.8 oz can with gauge and hose is easier to carry. Purchase requires EPA Section 608 certification.
Is the 24 lb R-404A Jug the Right Size?
The 24 lb jug suits refrigeration contractors charging a condensing unit after a compressor or coil replacement, servicing supermarket display cases, or keeping several ice machines and cold rooms running. It holds enough for full charges at a lower cost per pound than small cans.
Planning a conversion off R-404A? Lower-GWP replacements such as Opteon XP40 (R-449A) and R-448A are also available in 25 lb jugs.
Ideal for: Cold storage, supermarket display cases, ice machines, transport refrigeration, and R-502 retrofits.
Only need a top-off? The R-404A 27.8 oz can handles small charge adjustments.
Refrigerant purchases require the Refrigerant Agreement and proof of EPA Section 608 certification. Charging amounts depend on system design and operating conditions. For use by qualified HVAC/R technicians. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
Can R-404A replace R-502?
Yes. R-404A is a replacement for R-502 in transport refrigeration, and retrofitting existing R-502 installations with R-404A is possible. Follow the equipment manufacturer's retrofit guidance.
What oil does R-404A use?
R-404A uses polyol ester (POE) lubricant.
Why do bubble and dew points differ for R-404A?
R-404A is a blend, so its boiling point at 1.013 bar ranges from -46.5 °C (bubble) to -45.8 °C (dew), a small glide of about 0.7 °C.
Is there a lower-GWP option for R-404A equipment?
Yes. Opteon XP40 (R-449A) replaces R-404A in new equipment and retrofits and is rated 8–12% more energy efficient than R-404A.
Do you carry compressors for R-404A systems?
Yes. Budget Heating carries Copeland hermetic compressors rated for R-404A and other refrigeration compressors and supplies.
