SUBSTITUTE FOR R410A IN THE NEW EQUIPMENT

R452b is a non-ozone depleting, low global warming potential, HFO-based refrigerant to replace R410a in positive displacement, direct expansion air conditioning, heat pump and chiller applications.

​​R452b is intended for new equipment design only and is the preferred low-GWP replacement for R410a, as it offers the optimal balance of properties with an additional benefit of approximately 5% increase in energy efficiency while being easily convertible from R410a designs.

APPLICATIONS, PERFORMANCE, SAFETY AND ENVIRONMENTAL BENEFITS

R452b refrigerant

R452b helps deliver an optimal balance of performance, safety and design compatibility to replace R410a:

  • Improved performance: up to 5% energy efficiency improvement over R410a
  • Excellent performance in high ambient conditions
  • Mild flammability: ultra-low 2L class flammability properties
  • Equipment adaptability: close match to R410a with minimum changes required
  • Low GWP: 67% reduction in comparison to R410a
  • Very low temperature glide
