A-Gas R448A Solstice® N40 HFO Refrigerant
R448A, also known as Solstice® N40, is a lower-GWP HFO refrigerant blend used as a replacement for R404A and R22 in low and medium temperature refrigeration applications.
Designed for commercial refrigeration and transport refrigeration systems, R448A offers a lower global warming potential than R404A while closely matching the performance and properties of R404A and R22. A-Gas notes that R448A provides a combination of low GWP and high energy efficiency, with lower compressor discharge temperatures at both medium and low temperature conditions.

Safety & Documentation
R448A must be handled by appropriately licensed refrigeration and air-conditioning technicians. As a zeotropic refrigerant blend, it must be charged from the liquid phase to maintain accurate composition during installation and service.
Store cylinders in a cool, dry and well-ventilated area, away from direct sunlight. A-Gas notes that compressors must be charged with polyolester oils, and technicians should contact the compressor manufacturer for further system-specific oil compatibility guidance.
A-Gas R448A Solstice® N40 is a practical lower-GWP refrigerant option for suitable commercial and transport refrigeration systems where a non-flammable A1 replacement for R404A or R22 is required.
