Air Wizard for reducing compressedair consumption

By retrofitting an Air Wizard system in Contiform S stretch blow-moulders, substantial savings can be achieved.
Referenced to a Contiform S16 with 25,600 containers an hour and 6,000 working hours a year, this produces the following compressed- air savings: the reduction in the dead space involves downsizing the volume at the valve block and the blow nozzles, which for 0.5-l bottles reduces the consumption of compressed air from its previous 1,360 m³/h to a mere 1,017 m³/h.
Reducing the final blow-moulding pressure results in compressed-air consumption for a 2.0-l bottle of a mere 1,812 m³/h instead of the previous 2,455 m³/h.
Lastly, recycling the final-blow-moulding air means that part of it can be used during the pressure- relief phase for pre-blowing and stretching.
For a 2.5-l bottle this cuts the blow-mouldingair consumption from its previous 2,455 m³/h to a mere 2,198 m³/h. The previous consumption of stretching air, amounting to 174 m³/h, can be reduced to zero.
