R452A is a zeotropic refrigerant blend consisting of R-1234yf (HFO), R-125, and R-134a (HFCs), developed as a lower-GWP alternative to R404A and R507. It closely matches the thermodynamic performance of R404A, making it a suitable option for both new equipment and retrofits in low- and medium-temperature commercial and transport refrigeration systems. R452A delivers similar discharge temperatures and capacities while significantly reducing environmental impact, with a Global Warming Potential (GWP) approximately 45% lower than R404A.
This refrigerant is non-ozone-depleting and compatible with existing system components, requiring only minor adjustments when retrofitting from R404A. R452A operates with POE (Polyolester) lubricants and may require oil change or compatibility checks during conversion. It is particularly well-suited for refrigerated transport applications where maintaining system reliability and cooling efficiency under varying conditions is critical.
Applications:
✅Transport Refrigeration: Ideal for refrigerated trucks, trailers, and containers requiring reliable, low-temperature performance.
✅Commercial Refrigeration: Suitable for supermarkets, cold rooms, and food retail systems transitioning from R404A or R507.
✅Industrial Freezers: Used in industrial low- and medium-temperature refrigeration systems requiring reduced environmental impact without redesign.
