Top 10 Companies in the R-513A (GWP 631) HFO/HFC Blend for R-134a Marine Refrigeration Retrofit Market (2026): Market Leaders Powering Global Marine Refrigeration

MARKET INSIGHTS

Global R-513A (GWP 631) HFO/HFC Blend for R-134a Marine Refrigeration Retrofit Market size was valued at USD 187.4 million in 2025. The market is projected to grow from USD 198.6 million in 2026 to USD 374.2 million by 2034, exhibiting a CAGR of 8.2% during the forecast period.

R-513A is a non‑flammable, azeotropic‑like blend composed of R‑1234yf (HFO) and R‑134a (HFC), formulated specifically as a lower global warming potential alternative to pure R‑134a in refrigeration and air conditioning systems. With a GWP of 631 – significantly reduced compared to R‑134a’s GWP of 1,430 – R‑513A offers a thermodynamically compatible retrofit solution requiring minimal system modification, making it particularly well‑suited for marine refrigeration applications aboard commercial vessels, cruise ships, and naval platforms.

The market is gaining strong momentum driven by tightening international maritime environmental regulations, most notably the IMO’s greenhouse gas reduction strategy and the accelerating phase‑down of high‑GWP refrigerants under the Kigali Amendment to the Montreal Protocol. Furthermore, the European F‑Gas Regulation and similar regional mandates are compelling fleet operators to transition away from R‑134a, positioning R‑513A as a pragmatic, cost‑effective retrofit option. Honeywell and Chemours are among the prominent manufacturers actively supplying R‑513A under trade names Solstice® N13 and Opteon™ XP10, respectively, supporting the marine sector’s compliance‑driven refrigerant transition.
