Honeywell announced that its ultra low-global-warming-potential (GWP) refrigerant technology is supporting a new cooling system at the Eiffel Tower. The installation, which uses Honeywell’s Solstice® ze (R-1234ze) refrigerant, provides the tower’s west pillar with an energy-efficient and cost-effective solution that reduces greenhouse gas emissions.The Société d’Exploitation de la Tour Eiffel (SETE) replaced its aging system run with higher-GWP refrigerant R-407C with a contemporary system incorporating Honeywell’s solution and equipment provided by component manufacturer AF Energy and French refrigeration specialist ALM Froid. The solution met SETE’s strict criteria to transition to a high-performing, sustainable system with increased reliability, energy efficiency and improved safety to meet EU regulations and reduce its carbon footprint.
In comparison to R-407C, which has a high GWP of 1774, Solstice ze has an ultra-low GWP of 1, which is 99.9 percent lower than the legacy refrigerant.
Honeywell’s breakthrough Solstice® hydrofluoroolefin (HFO) technology, which helps customers meet environmental, social and governance (ESG) goals, improves energy efficiency without sacrificing end-product performance. It is used in various applications, including refrigerants for supermarkets, air conditioning for cars and trucks, blowing agents for insulation, propellants for personal and household care and solvents for cleaning solutions.
