We’ve collaborated with many industrial facilities around Ohio to help them with their blow molding machinery. Through an energy analysis, we have the opportunity to identify weaknesses in your systems and suggest ways to enhance system efficiency and lower utility costs.
In the case of one of our partners, we were able to implement an air recovery system that saves from 10% to 40% on energy costs, with typical savings being around 25%. The purpose of the air recovery system is to convert the exhausted compressed air into pre-blow air. Each bottle in the air recovery system is filled with a volume of compressed air. After the bottle is molded into the proper shape, the compressed air is released, and the bottle moves down the production line. However, rather than releasing the air, it’s captured into a bladder and redistributed into the beginning of the process for the next plastic molding.
After implementing the air recovery system, we helped our partner reduce the compressed air high pressure system by 259 scfm. In addition, this translates into an 87.8 kW impact, or 746,245 kWh/year.
