R407A Refrigerant — Lower-GWP R404A Replacement for Commercial Refrigeration

R-407A is an HFC blend refrigerant used primarily as a lower-GWP alternative to R404A and R507 in medium and low-temperature commercial refrigeration systems. It is a zeotropic blend of R32, R125, and R134a, engineered to deliver comparable performance to R404A at a significantly reduced global warming potential. Refrigerant Inc stocks genuine, virgin R407A in 25 lb cylinders with free shipping to all 48 continental states.

What Systems Use R407A?

R407A is used in medium and low-temperature commercial refrigeration applications, including:

• Supermarket refrigeration — Medium and low-temperature display cases and rack systems
• Walk-in coolers and freezers — Commercial food service and food distribution facilities
• Cold storage — Refrigerated warehousing operating at low and medium temperatures
• Transport refrigeration — Some reefer trailer and refrigerated transport applications
• Industrial refrigeration — Process cooling and industrial cold storage systems

R407A is not used in residential or light commercial air conditioning — it is specifically a commercial refrigeration refrigerant. Always verify the equipment nameplate before purchasing.

R407A vs. R404A — Key Differences

• GWP: R407A has a GWP of approximately 2,107 — roughly half of R404A's 3,922, making it a meaningful step down in environmental impact
• Temperature glide: R407A is a zeotropic blend with temperature glide, unlike R404A which has minimal glide. This means R407A must be charged as liquid and may require TXV evaluation during retrofit
• Performance: R407A delivers comparable cooling capacity to R404A in medium and low-temperature applications, with similar operating pressures
• Oil: R407A requires POE lubricant — the same as R404A in most modern commercial refrigeration systems

R407A as an R404A Retrofit

R407A is used as a retrofit refrigerant in existing R404A commercial refrigeration systems. Key considerations:

• POE oil required — Most R404A systems already use POE lubricant, which is compatible with R407A. Verify before retrofitting.
• Recover R404A first — Fully recover all existing R404A before introducing R407A. Do not mix refrigerants.
• Charge as liquid — R407A has temperature glide and must be charged in liquid phase to maintain proper blend composition.
• TXV evaluation — The expansion valve may need adjustment or replacement depending on system design. Consult manufacturer retrofit documentation.
• Charge weight — Charge weight for R407A may differ slightly from the original R404A specification. Refer to refrigerant manufacturer guidelines for your application.
• Label the system — After retrofitting, update the equipment label with new refrigerant type, charge weight, and conversion date.

R407A vs. R448A and R449A

R407A, R448A, and R449A are all lower-GWP alternatives to R404A. Here's how they compare:

• R407A — GWP ~2,107; well-established in commercial refrigeration; good balance of performance and GWP reduction
• R448A (Solstice N40) — GWP ~1,387; lower GWP than R407A; particularly strong in low-temperature applications
• R449A (XP40) — GWP ~1,397; similar to R448A; strong in medium-temperature applications

R448A and R449A offer lower GWP than R407A. However, R407A is an established, widely stocked option that many contractors and equipment manufacturers have approved retrofit procedures for. If your equipment manufacturer specifies R407A, it's the right choice for your application.

Frequently Asked Questions

What is R407A used for?
R407A is used in medium and low-temperature commercial refrigeration — supermarket cases, walk-in coolers and freezers, cold storage, and transport refrigeration. It is a lower-GWP alternative to R404A and R507 in these applications.

Is R407A the same as R407C?
No. R407A and R407C are different refrigerant blends with different compositions and applications. R407A (a blend of R32, R125, and R134a) is designed for commercial refrigeration. R407C (also R32, R125, and R134a but in different proportions) is used in HVAC air conditioning and chiller applications. They are not interchangeable.

Can R407A be used in an R404A system without modification?
R407A is close to a drop-in for many R404A systems but POE oil is required, charge as liquid is essential due to temperature glide, and TXV adjustment may be needed. Follow the refrigerant manufacturer's retrofit guidelines for your specific equipment.

Does R407A require special service equipment?
No. R407A is A1 classified — non-flammable and low toxicity. Standard commercial refrigeration service equipment rated for HFC refrigerants is compatible. No A2L tools required.

Why does R407A need to be charged as liquid?
R407A is a zeotropic blend with temperature glide, meaning its component refrigerants have slightly different boiling points. Charging as vapor causes the blend to fractionate — the components enter the system in an off-ratio mixture, resulting in incorrect operating pressures and reduced performance. Always charge R407A from the liquid port or invert the cylinder.

Is R407A being phased out?
R407A has a GWP of approximately 2,107 and is subject to EPA AIM Act HFC phasedown regulations. While it represents a meaningful GWP reduction from R404A, it remains a regulated HFC. It can continue to be purchased and used for servicing existing equipment. For lower-GWP options, see R448A and R449A.
