Double-acting Reciprocating Air Compressors for P.E.T. Bottle Blowing

By Donald J. Oitker

Most P.E.T. bottle-blowing machines require anywhere from 550 psig (38 barg) to 580 psig (40 barg) and an air flow of 247 cfm FAD (420 m3/hr) to 3700 cfm FAD (6290 m3/hr). The air compressor technology used most prevalently for this application is the double-acting, oil-free, water-cooled, reciprocating air compressor. With the higher pressures and air flows that are required, the P.E.T. bottle blowing market is a strong niche market for the double-acting oil-free reciprocating (piston) compressors.

Energy Management at Visteon

Compressed Air Best Practices® Magazine interviewed Jennifer Meier, Global Energy & Engineering Manager, at Visteon Corporation.

There are three main segments in Visteon's climate group are climate systems, powertrain cooling and engine induction. Climate systems include refrigeration compressors, fluid transport, heat exchangers, battery cooling modules, climate controls, auto defog/demist systems, and multi-zone HVAC systems. Powertrain cooling systems include heat exchangers (radiators, condensers, charge-air, exhaust-gas), airflow management, and diesel and hybrid thermal management. Engine induction includes air induction systems and intake manifolds.

Sanity Check: Will the Standby Air Compressors Start-Up During Cold Weather?

By Gary Wamsley, PE, CEM

Several days prior to our visit, during a cold winter evening, the lead air compressor in one mechanical room tripped off (apparently due to a fouled intake filter and low air flow through the machine). A crucial situation then developed: The "stand-by" unit did not start. Maintenance folks had to be called in to get a compressor running. That delay caused low plant air pressure, production curtailment and some defective product. They had yet to determine the conditions that caused the "no-start".
