GGE developed a parallel solution for the 0°C chambers that represent
around 50% of the plant’s total cooling space.
An air-to-water liquid outdoor chiller using propylene-glycol at -6/0°C as
the cooling substance was installed.
With a cooling capacity of 760 kW, the energy efficiency ratio is twice as
high as for the existing technology used at the Zalog plant. Under
Eurovent conditions, this impressive chiller weighing 8 tons could have a
capacity as strong as 1300 kW.
