Such reduction increases the risk of interruption if a compressor goes offline, so maintain the reliability of the new configuration. Once you have the most workable solution to meet the desired priorities at the lowest operating cost, develop a detailed implementation plan that includes capital and installation costs, engineering, project management, contingency, shipping and taxes Develop the chronological order to minimize disruption to production and to accomplish as much as possible during normal working hours. Tell the audit teams that the deliverables you expect might not be identical to the things they sell. Particularly with compressed air, you must apply, rather than buy, a solution. If done correctly, the effort is demanding and difficult. Finally, determine the operating financials and return on investment. This might require considering capital depreciation or taxes on the reduction in operating cost. In a lean economy, you can’t overlook compressed air opportunity expense as a viable area to evaluate. Be mindful of how critical it is to make the ROI on an approved project. As important as compressed air is to most plants, it doesn’t mean that it should be maintained at any cost.
