R452B Solstice L41y

  • Solstice L41y (R452B) is a non-ozone depleting, zeotropic blend designed to serve as a low GWP alternative to R410A in positive displacement comfort air conditioning and reversible heating applications.
  • A key feature of Solstice L41y is its 67% lower GWP with similar efficiency and matching capacity to R410A, helping to further minimise the re-design costs and capital expenditures.
  • The design compatibility of Solstice L41y enables OEMs to transition their R410A equipment to a lower GWP alternative faster.
  • Solstice L41y discharge temperature is much lower than R32 and very close to R410A indicating that discharge temperature mitigation may not be required.
  • Solstice L41y has lower mass flow rate than R410A which leads to a lower pressure drop and eliminates potential design cost increase in the heat exchanger.
