Zanotti Confirms new low GWP refrigerant for Monoblock Cooling Systems

Zanotti is a leading manufacturer of refrigeration systems for commercial, industrial and transport applications. It works with CO2, propane and ammonia, but is aware that these are not suitable for every application. When Honeywell’s Solstice® L40X (R-455A) came to its attention, Zanotti embarked on a test programme to assess the refrigerant as a potential replacement for R-404A in its range of monoblock cooling systems. Mindful of the necessity to further develop their systems for use with refrigerants showing lowest-possible global warming potential (GWP), Zanotti found in R-455A an optimal solution for such applications.

  • Solstice L40X (R-455A) is a zeotropic blend refrigerant which is designed for low-, medium- and high-temperature applications in new systems.
  • Low GWP of only 146, compliant with the F-Gas Regulation
  • Close capacity match to R-404A and, compared to a propane (R-290) refrigerant, extended capacity by 20%, with improved energy efficiency and a similar COP
  • Lower flammability risk than R-290.
  • Suitable for plug-in type cabinets, condensing units, waterloop systems and monoblocks for cold rooms and freezer rooms, heat pumps, and chillers.
