Market Insight: In Nigeria, R-407C is the “go-to” for maintaining large chillers in hotels and corporate towers. This is the “Engineer’s Choice” for professional retrofits. Genuine Chemours product is essential for high-end facility managers who need to avoid the risk of “fake gas” damaging multi-million Naira chiller systems.
Tech Note: When selling this for a retrofit, technician should perform a thorough system flush and replaces the filter drier. Also, remind them that R-407C has a “temperature glide”—this information is vital for setting superheat and subcooling correctly during installation.
