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 Cooling

MARKET INSIGHTS

The Global R-513A (GWP 631) HFO/HFC Blend for R-134a Marine Refrigeration Retrofit Market size was valued at USD 68.4 million in 2025. The market is projected to grow from USD 74.2 million in 2026 to USD 142.7 million by 2034, exhibiting a CAGR of 8.5% during the forecast period.

R-513A is a zeotropic HFO/HFC blend refrigerant designed as a lower GWP retrofit solution for R-134a systems. With a GWP of 631, it offers approximately a 56% reduction compared to R-134a while maintaining similar thermodynamic performance, making it suitable for drop‑in or minimal modification retrofits in marine refrigeration applications. This blend is non‑flammable (A1 safety classification) and is increasingly utilized in shipboard cooling systems, including cargo refrigeration, provision stores, and air conditioning on commercial vessels, fishing fleets, and specialized marine transport.

The market is experiencing steady growth driven by stringent international maritime environmental regulations, including IMO initiatives targeting greenhouse gas reductions from shipping operations. Vessel operators are retrofitting existing R-134a systems to comply with evolving low‑GWP requirements and to extend equipment life without full system replacements. Furthermore, the expansion of global maritime trade and the need for reliable, energy‑efficient refrigeration on board vessels contribute to demand. Key industry players are supporting adoption through dedicated retrofit guidelines and supply chain enhancements for marine‑grade R-513A formulations. While retrofits present technical considerations such as capacity matching and lubricant compatibility, the blend’s favorable properties enable smoother transitions in many medium and high‑temperature marine applications.
