How to reduce compressed air pressure when blowing PET

 The price of plastic packaging is decreasing due to new technologies. Companies are working hard to develop new containers. However, PET companies also need to be aware of ways to reduce energy costs. For example, in PET blow molding, reducing compressed air pressure can reduce energy costs. High-pressure air recirculation is one of several ways to reduce energy consumption in PET blow molding machines.

Ensure the correct air pressure setting

Industrial blow molding machines require a constant supply of compressed air. However, maintaining a steady supply can be difficult. A PET machine must run fast, blowing out up to 2,400 bottles per hour. This high volume can cause a rapid drop in pressure in the filter and manifold. To compensate, the air compressor often runs at a higher level than necessary. Sometimes, PET blow molding machine manufacturers have to stop production on one machine to ensure adequate pressure in the other machines.

Because of these dynamics, the design of the compressed air system is critical. As a rule, manufacturers create two separate compressed air systems. One for high pressure and one for low pressure. This prevents the PET machine from interfering with the other machines in the plant. It is the ideal system for reducing energy consumption.

Use of pneumatic components

Another way to reduce the air pressure drop is to use local air tanks. In this case, pneumatic elements can help. You should place the tank close to the blow molding machine and use large pipes to meet the need. You can install a small pneumatic component to optimize the airflow. You should consult an expert for this, as measuring and determining the pressure drop can be difficult.

 

Cleaning and filtering compressed air

Sometimes problems with compressed air are caused by cleanliness issues. They range from oil to water vapor or particles. Since this air will come in contact with the beverage container, its quality is very important. You can install two filters at the point where this air enters the PET blowing machine. The filtration of the air ensures maximum purity.
