Thanks to the absorption unit, Alpro is saving EUR 49,000 per year in operating costs. A mechanical compressor – electrically powered – is usually required to produce cold. This consumes about 80% of the total energy required by the cooling system. A water-ammoniac absorption unit can lower these costs, as residual heat is used to power the mechanical compressor. This reduces the maintenance costs compared with conventional heat pumps/cooling for cold production.
