Reinject medium pressure to maximize savings
The high pressure compressed air used in the blow moulding machines was traditionally blown off to the atmosphere. Nowadays, many blow moulding machines are equipped with air recovery systems. The recovered air is re-used both for pre-blow and reinjection.
But how much energy can you save?
