Replacement of "kegs on legs", "Sputniks" or stainless steel totes by bag-in-box systems happens very often. Using our steam sterrilizable aseptic valves this is an relative simple change, as existing equipment can be used. Generally speaking there are three main advantages for choosing a liner system. Cost advantage (container purchase, cleaning, lost equipment), logistic optimization(storage and return transport) and investing capacity. Stainless steel containers will cost about 1500-2500 euro/container, which is considerably high cost in both purchasing and depreciation. Furthermore they are not foldable or disposable, making return logistics a cost-intensive practise.
