Hanon Systems Pivots to PFAS-Free Refrigerants for Automotive Thermal Systems
As the automotive industry faces mounting pressure to curb environmental contaminants, Hanon Systems has released a technical roadmap detailing its shift toward natural refrigerants. The white paper outlines a transition away from traditional fluorinated options, like R1234yf, which risk creating long-term environmental hazards through trifluoroacetic acid degradation.
The Seoul-based thermal management firm is betting on carbon dioxide (R744) and propane (R290) as the primary pillars for its next generation of cooling technology. Hanon Systems has already secured a foothold with its R744-based hardware—including electric compressors and gas coolers—which currently operate in more than one million vehicles globally.
Beyond current deployments, the company is intensifying research into R290-based systems to provide a PFAS-free alternative for future vehicle platforms. Vice Chairman and CEO Soo Il Lee noted that the publication serves both as a demonstration of the company’s engineering capacity and a proactive response to tightening global environmental regulations. The full documentation is now available through the company’s official portal for automotive manufacturers and industry stakeholders.
