R449A (XP40) Refrigerant — Low-GWP R404A Replacement, Free Nationwide Shipping

R-449A, sold under the brand name XP40 by Chemours (the same company behind Freon), is a leading low-GWP refrigerant blend designed to replace R404A and R507 in medium and low temperature commercial refrigeration systems. With a GWP of approximately 1,397 — less than 36% of R404A's 3,922 — XP40 is widely used by supermarkets, cold storage operators, and food service businesses transitioning away from high-GWP refrigerants. Refrigerant Inc stocks genuine, virgin R449A/XP40 with free shipping to all 48 continental states.

What Systems Use R449A (XP40)?

R449A is designed for medium and low temperature commercial refrigeration, including:

• Supermarket refrigeration systems — Medium-temp display cases, reach-in coolers, and multi-deck cases
• Walk-in coolers and freezers — Food service and food distribution facilities
• Cold storage — Commercial and industrial refrigerated warehousing
• Transport refrigeration — Reefer trailers and refrigerated vans retrofitted from R404A or R507
• Vending and beverage equipment — Large commercial coolers and vending machines

R449A (XP40) as an R404A Retrofit

XP40 is one of the most specified R404A replacements by equipment manufacturers and refrigeration contractors. Key retrofit considerations:

• POE oil required: R449A requires POE lubricant. Most R404A and R507 systems already use POE — verify before converting. If mineral oil is present, a full oil change is required.
• TXV evaluation: Expansion valve adjustment or replacement may be needed depending on the system. Consult Chemours' XP40 retrofit documentation for your specific equipment.
• Fully recover existing refrigerant first: Remove all R404A or R507 before introducing R449A. Do not mix refrigerants.
• Charge weight: R449A charge weight is typically similar to or slightly lower than the R404A charge — refer to Chemours' retrofit guidelines for exact weight recommendations by system type.
• Label the system: After retrofitting, update the equipment label with the new refrigerant, charge weight, and conversion date.

R449A vs. R448A — Choosing the Right R404A Replacement

Both R449A (XP40) and R448A (Solstice N40) are top-tier R404A replacements. The difference is subtle:

• R449A (XP40) — Tends to perform slightly better in medium-temperature applications; widely specified by Chemours and used in supermarket medium-temp cases and AC applications
• R448A (Solstice N40) — Tends to perform slightly better in low-temperature applications; often preferred for frozen food cases and low-temp storage

In practice, both work well across the full range of commercial refrigeration temperatures. Check whether the equipment manufacturer has a specific recommendation, or call us at 888-593-7366 for guidance.

Frequently Asked Questions

What is XP40 refrigerant?
XP40 is the brand name Chemours uses for R449A. They are the same refrigerant — XP40 is simply the trademarked product name. You may see it referenced as R449A, XP40, or R449A/XP40 in service literature and equipment documentation.

Is R449A a drop-in for R404A?
R449A is close to a drop-in for many R404A systems but POE oil is required, and TXV adjustment may be necessary. Follow Chemours' XP40 retrofit guidelines for your equipment type. Charge weight may also differ slightly from the original R404A specification.

Can R449A replace R507 as well as R404A?
Yes. R449A is approved as a replacement for both R404A and R507 in medium and low temperature commercial refrigeration applications. The retrofit procedure is essentially the same.

Why is transitioning away from R404A important?
R404A has a GWP of 3,922 — one of the highest of any commonly used refrigerant. EPA AIM Act HFC phasedown regulations are progressively restricting high-GWP refrigerants. Transitioning to R449A now reduces regulatory risk and positions your customers' equipment for long-term compliance.

Does R449A require new service equipment?
No special equipment is required beyond what you already use for R404A service — standard recovery machines, manifold gauges, and vacuum pumps rated for HFC refrigerants will work fine. R449A is A1 classified (non-flammable, low toxicity).
