FluoroFusion Introduces R-4106A (410 Sexy)

R-4106A is FluoroFusion's patented A2L refrigerant blend, engineered as a direct alternative to R-454B and sold under the Arctic Eagle® brand. It is EPA SNAP approved for new equipment. Retrofit approval is pending.

 

Performance vs. R-454B

Thermodynamic cycle analysis, NIST REFPROP v10, nine operating conditions (evaporator −25 °F to 130 °F):

• Cooling capacity: +6.6% average (range +5.0% to +8.5%), modeled

• Efficiency (COP): +2.7% average (range +1.4% to +3.9%), modeled

• TFA formation: roughly a 90% reduction versus R-454B

 

The Compliance & Safety Advantage

R-4106A has a blend GWP of 681 (40 CFR 84.64), below the 700 GWP limit for new residential and light commercial A/C and heat pump systems. For equipment application it carries the same ASHRAE A2L classification as R-454B. For transport and storage it is classified non-flammable under DOT, OSHA, NFPA and NEC, so it isn't subject to flammable-goods limits on truck stock or in-facility storage.

 

Why Choose R-4106A?

• Carry more, store more: DOT non-flammable for transport and storage

• GWP is one number. R-4106A is designed around what a refrigerant turns into, with roughly 90% less TFA formation than R-454B

• Made in NC USA with global components: manufactured in Clayton, North Carolina, for supply security

• Circular economy: net GWP below 10 on a production/allocation consumption basis when formulated from reclaimed components

• POE lubricant. Zeotropic blend: charge in the liquid phase

• Covered by U.S. Patent 12,540,265 B2; presented at the 21st International Refrigeration and Air Conditioning Conference at Purdue, July 2026
