Focus Industry PLASTICS BLOW-MOLDING | 04/08 | How are blow-molders reducing their carbon footprint? Blow-molders are reducing their carbon footprint by using lighter plastics and by consuming less energy. Lighter PET plastics are being used for water bottles, for example. We just attended a conference where they showed positive test results on half-liter water bottles, using less than 9 grams of PET plastic material. This amounts to over one third less material. Less plastic used means a reduced carbon footprint. The lighter-weight bottles are also allowing for 28–30 bar (400–429 psig) air pressure. This can save considerable energy versus using 40 bar air (575 psig) in the blowmolding machine. The blow-molding machine manufacturers are designing machines that use less air at lower pressures and the blowmolders themselves are trying to optimize their compressed air systems. our 777 scfm compressor turns at 500 rpm. Other reciprocating compressor designs will turn at 735 rpm. This means less wear on connecting rods, main shaft bearings, connecting rod bearings and other components. This also means the air compressor is generating less heat — which the factory’s HVAC system must compensate for. AF compressor designs also feature the fewest valves in industry. To use the example of the 777 cfm unit, our design has only 12 valves. Other reciprocating compressors can have 24 valves. We accomplish this in our over-all design including having a dual-acting first-stage compression chamber which compresses air on both the up and down strokes. Fewer valves equates to greater reliability. Blow-Molding Machine Manufacturers Sidel Krones SIPA Nissei SIG MAG SIAPI In 1973, We Introduced Energy Conservation Through Ultrasound 35 Years Later, Our Clients Have Saved Millions and Helped Improve The Environment Why has the three-stage, oil-free reciprocating compressor been the workhorse for PET applications? It starts with reliability and ends with efficiency. Blow-molders have high-volume, round-theclock operations, which can tolerate zero downtime. The three-stage design (in an L or W configuration) is an incredibly robust design for an air compressor. The true engineering behind AF designs lies in delivering high volumes of air while running the compressor at slow speeds. This delivers compressed air energy to the process while reducing wear on critical components and reducing downtime. To give you an example, Put a Compressed Air & Steam Trap Leak Control Program In The Palm of Your Hand! UE Systems has been providing practical, real-world solutions to detect and prevent energy waste in plants before the idea of conservation became trendy. We have provided thousands of clients with the ultrasonic equipment they need to increase productivity while ﬁnding millions of dollars in energy savings. Poorly maintained systems cost you and the environment. With $3.2 billion dollars of compressed air energy waste last year, it’s time to think green and big savings with UE Systems.
