Measuring Energy Savings at VeralliaCompressed Air Best Practices® interviewed Gregory Rhames, Asset Reliability Manager/Energy Manager at Verallia. As background, Verallia is the packaging division of Saint-Gobain. Verallia employs 15,500 people globally and makes about 25 billion glass bottles and jars each year. We employ 350 people at Madera where we produce about 1 million wine, champagne and sake bottles per day. Our company is dedicated to energy efficiency and maintaining a sustainable global habitat. |
Bottler Best Practices in CaliforniaBottling companies and breweries, in California, are benefiting from a three-step system assessment process aimed at reducing the electrical consumption of their compressed air systems. The three-step process reduces compressed air demand in bottling lines by focusing on open blowing and idle equipment, and then improves the speci c power (reducing the energy consumption) of the air compressors. |
PET Bottle Blowing EfficiencyThe average stretch blow molder working with PET has 2,000 to 4,000 horsepower of installed air compressors representing 35-40% of the facilities' total energy bill. Veteran system auditor, Dean Smith from iZ Systems, talks about eliminating pressure drops, of more than 50 psi, inside rotary reheat stretch blow molding machines. |
Festo Optimizes Compressed Air Consumption at VolkswagenMany passenger cars on roads in Germany contain efficiency concepts that make a considerable contribution to lowering emissions. Automotive manufacturers such as VW have gone even further than this, by applying efficiency strategies in their own value added chain. Because the benefits of pneumatics in automotive industry production processes have seen pneumatic actuation win over other drive technologies, efficient use of compressed air plays a key role in increasing energy efficiency. |
Are Compressed Air Leaks Worth Fixing?Why are compressed air leak programs often ignored or even discouraged by management, in addition to some energy recovery minded third parties? This problem can be summed up as “Over Promise” and “Lack of Delivery”. In the 1990’s, the basic compressed air inefficiency energy transfer became a prime target for energy reduction programs promising great results with many low investments. Good payback programs, which they are indeed. |
