R515B Solstice® N15

R-515B (Solstice® N15)

Very low GWP (293) A1 safety class, energy-efficient alternative to traditional refrigerants for air-cooled and water-cooled chillers in a range of applications including supermarkets, commercial buildings and crane cab air conditioning.

Features and Benefits

  • Very Low GWP – Long term sustainable and compliant with F-Gas legislation
  • Azeotropic refrigerant blend – can be used in direct expansion and flooded systems. Negligible temperature glide.
  • Comparable energy efficiency to R-134a – Lower indirect emissions and lower operating costs.
  • Approved by equipment manufacturers –New equipment available.
  • A1 (non-flammable) safety class – Ideal retrofit candidate for R-227ea.

Packaging and Supply

  • Climalife supply R-515B in 12.5kg and 60kg returnable cylinders.
  • Conforms to AHRI 700-2016 specifications.

Why Choose Climalife?

Climalife are a key player in the distribution of refrigerants and other climate control products, with a nationwide distribution network and product knowledge that is second to none.

How does R-515B compare to R-134a?

R-515B has a lower cooling performance compared to R-134a but good energy efficiency making it an ideal very low GWP alternative to R‑134a in new equipment.

Full theoretical performance comparisons at customer specified conditions are available from Climalife on request.
