FAQ
Is R404A compatible with my system?
Use R404A only in equipment designed or formally approved for R404A. Do not mix it with R407A, R448A, R449A, or another refrigerant. Before purchasing, check the equipment nameplate and manufacturer documentation. If you are unsure, send us a clear photo of the nameplate and consult a qualified technician.
What is R404A commonly used for?
R404A refrigerant blend is intended for compatible commercial refrigeration, cold-storage, and food-processing equipment. The listed applications are general guidance only; the equipment nameplate and manufacturer specification determine the correct refrigerant.
How much refrigerant is included in the R404A cylinder?
The cylinder contains 24 lb (10.9 kg) net weight of R404A refrigerant. Net contents do not include the cylinder tare weight or outer packaging. Verify the product label, seal, and cylinder condition when the shipment arrives.
Can I mix R404A with another refrigerant or use it as a drop-in replacement?
No. Refrigerants are not interchangeable and should not be mixed. Use only the refrigerant approved for the equipment. Any conversion or retrofit must follow the equipment or retrofit manufacturer's written requirements and be completed by a qualified professional.
Do I need a certified technician to handle R404A?
Recovery, charging, leak testing, and system repair should be performed by a qualified refrigeration professional using equipment approved for R404A. Purchasing, handling, recovery, transport, and installation requirements may vary by product, application, and location. Confirm the rules that apply to you before ordering or using the product.
