A low-GWP cooling system for the Eiffel Tower

The ageing R407C cooling system in the tower’s west pillar has been replaced with an energy efficient system using low GWP R1234ze(E).
 
The Société d’Exploitation de la Tour Eiffel (SETE), has replaced the ageing R407C cooling system on the tower’s west pillar with an energy efficient system incorporating Honeywell’s R1234ze( E) low GWP refrigerant and equipment provided by component manufacturer AF Energy and French refrigeration specialist ALM Froid. In comparison to HFC R407C, which has a high GWP of 1700, R1234ze( E) is an HFO with a low GWP <1.
