| PLASTICS BLOW-MOLDING GUARANTEEING AUDIT ROI FOR BLOW-MOLDERS Step 1 involves accurately identifying measuring savings and quantifying the costs required to generate the ROI. The key is to focus on the costs involved with implementing and verifying the project. It is important to partner with the company and identify what resources the company will make available to implement the project. The Analysis and Quantification Step must detail the costs involved with ensuring ROI and detail the verification dates and process. Normally, the goal is to be successful in one facility of the corporation and then to roll out the model to the rest of the factories in the organization. By having a detailed Analysis and Quantification Step 1,which includes all the costs involved to prove that ROI has been attained, the buy-in and support of senior management will be greater. 04/08 | Measuring Savings Most facilities do not design their compressed air systems based upon an understanding of the ranges of demand and the rates (or speed) of change in demand. Almost all facilities design their compressed air systems around maximum air-flow demands and maximum air pressure requirements. This is where the big opportunity exists for improvement. What and how you measure becomes the key factor when measuring savings. 1. Measuring Power: We do measurements to know a compressors’ true kW power consumption loaded and unloaded. We do not use product name-plate data. This is important. We are measuring amps to determine power factors and motor efficiencies Measuring Pressure: We measure pressure and the rate of change of pressure. Know the storage values in the system and its’ rate of change. This gives us a handle on the production side and the demands being placed upon the air compressor system 2.
